Introduction Our phenotype is determined by the genotype, which is the genetic makeup of a particular organism. The phenotype is visible amongst the physical appearance of the organism. However, the genotype of the organism is not the only factor that affects the organism’s phenotype because there is a distinction between simple traits and complex traits. While simple traits represent that genes directly affect the phenotype, complex traits include the influence of various environmental factors that affect the genotype, which is revealed in the organism’s phenotype. Some of these environmental factors include the access to diet, nutrition, hormone therapy, various diseases, exposure to light, physical activities, geographical location, climate, and lifestyle.
In this project, we investigated how several environmental factors and genotype affect our phenotype. In the lab, we examined and surveyed several students to determine whether or not several variables such as parent height have an effect on student height. In addition, we examined whether the environment the students are exposed to such as geographical location and latitude affects our body proportions and whether our grip strength is affected by the length of our upper body.

The Height of the students will be correlated with their parent’s height because of the

The students’ height was measured in centimeters by using a measuring tape. The heights of the parents were also recorded in centimeters. The seated height of the students was recorded in centimeters by using a measuring tape whilst the subject sat on a chair. The students’ forearm length was also measured up to the students’ wrists by using a measuring tape and recorded in centimeters. In addition, the latitude of the subjects was recorded in degrees. Lastly, the grip strength of the students was recorded in kilograms by using a handgrip
The Week 4 assignments are addressed on how to use the observational tools in order to evaluate the development and create the activities that promote young children 's development. For example, assignment 4.3 Running Record is one of useful observational tools that educators can use. It requires sensitive observation and writing skills in order to collect detailed information. By using the running record, educator can use the data to evaluate the development of the child and create helpful activities that will help the development of the child.
In other scenarios like hypertension or high cholesterol, certain genetic variations may interact with environmental stimuli to cause disease”
One of the longest and oldest debate in science and psychology is the debate of nature versus nurture. Simply, it is trying to answer the question of where one gets their traits. Some think that it is mostly from their DNA, having predisposed traits. This is the ‘nature side of the argument’. Although others, on the nurture side, believe our traits are based on our experiences, our childhood, and external forces.
The dataset used in the analysis is the grades.dat; it was used to analyze the performance of the students in the GPA and the final. The dataset includes information collected from the survey of 105 students and includes variables such as performance and demographic variables. The variable GPA measures the performance
Dr. Rettew connects to class discussions and readings on shared and unshared environmental influences, evocative gene environment correlation, temperament, and the goodness-of-fit. Twins that with unshared environmental influences, such as different placentas, could adapt different temperaments (Berk, 2009). Also, twins that have been adopted into separate families could have different personality traits because they lived in completely different environments their whole life, even if they shared environmental influences of the same placenta (Berk, 2009). With an evocative gene environment correlation, a child’s genotype could draw in a certain type of environment, such as babies who appear more attractive will receive more attention (Berk, 2009). The type of attention a child gets could affect its temperament.
The environment in which a population lives in selects which traits are desirable or not and that reflects on the members reproduction fitness. For example, an elephant may be born with a longer neck. This allows the elephant to reach higher branches and to consume more food, thus the long necked elephants will reproduce more than the short necked elephants. Eventually the elephants with long necks will out number thepreviously dominant short necked elephants (Stanford,Allen, and Anton 18).
Environmental factors and the affects it has on brain growth and development What affects a child’s brain growth and development? This is a question that teachers, doctors, and parents often ask themselves. The answer is there are many things that affect a child’s brain growth and development. In fact, everything that a child experiences can play an important role. The factor that I want to focus on is the environment.
Human development happens continuously throughout ones lifespan as we develop and change. Genes exemplify biological factors in human development. Some biological factors are visible, for example skin tone and hair color. Some biological factors are unobserved, for instance genetic abnormalities and risks for diseases. From a biopsychosocial perspective what one becomes is the product of genes, or biological forces.
The environment where a child is been raised plays a huge role on its psychological development. There are a lot of environmental influences that might affect their overall development and behavior. These influences might come from a prenatal environment, physical environment, social environment, cultural environment, learning environment, economic environment, emotional environment and family environment. All these environments are important for the success and for the happiness throughout their lifecourse. According to the World Health Organization, the first 8 years of life will affect a child’s health, education and economic participation for the rest of its life.
Nature can loosely be defined as genetic inheritance and genetic makeup which a person inherits from their parents at the time of conception and carries throughout life. What makes nurture important is that it can change the genetic makeup and genetic inheritance that people inherited from their parents. In a recent study in the University of Manchester, Reinmar Hager and Jason Wolf at the Faculty of life Sciences together with their collaborator James Cheverud at St Louis have shown how maternal environment can affect how genes are expressed, influencing the body weight and growth of young mice, even if they are not related to their mother. They have thus revealed that environment may affect how genes are expressed. Focusing on genomic imprinting, the researchers had shown that the environment has had a strong effect on how imprinting influences body weight and growth in mice (Hawoth).
After comparing shared and non-shared environment, it was also seen in both studies that a non-shared environment has higher variance compared to a shared environment variance. In addition to having a similar conclusion, there was a trend within the numbers caused by the mean age of the samples. Samples from the Bergeman et al. study had an average age of 59 years while the samples from the Jang et al. study had an average of 31 years. This concludes that age can also be a factor that would influence the environment and the genetic influence (Table 3)
Phenotype variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive. When reproductive isolation occurs new species will form. Charles Darwin has been quoted as saying, “Variation is a feature of natural populations and every population
Q.1: What micro environmental factors have affected Target’s performance over the past few years? Over the past few years, following are the factors that have affected Target’s performance: 1. Competitors: Walmart’s strategy of providing products at a very low price, affected the consumers in the economic crisis of 2008. This led to Target’s decline in market share as Wal-Mart had a huge micro environment affect as a competitor.
Nature and Nurture Influences on Child Development Karla White ECE 205: Introduction to Child Development Instructor: Alesia Lane October 2, 2017 Nature and Nurture Influences on Child Development Describe the relationship between nature versus nurture. The nature vs. nature debate is the scientific, cultural, and philosophical debate about whether human culture, behavior, and personality are caused primarily by nature or nurture. Nature is often defined in this debate as genetic or hormone-based behaviors. Our genes determine the different traits that we have, such as eye color, hair, ear size, height and other traits.
skin colour is a polygenic trait which is controlled by at least 3 genes as discussed in Cambell Biology. However polygenic traits are often influence by environmental factors. i.e. in warmer, sunnier climates skin colour tends to be darker due to the suns uv rays. The more genes that contribute to a trait the greater the variation. Height is a polygenic trait in humans which accounts for the huge variation among the human population.
