    Although it only takes a single mutant allele to express the mutant phenotype, mutant homozygotes (if they survive into adulthood) tend to have a more severe or even unique phenotype compared to heterozygotes for the same mutant allele. For example, homozygotes for Brd1 mutation display duplication and thickening of humeral, notopleural, and scutellar bristles compared to both wild-type

  • Genotypes In My Family

    707 Words  | 3 Pages

    Heredity is basically the passing on of genetic traits from parents to offspring. Both phenotypes and genotypes are passed down from one’s parents. A genotype is the genetic code of one’s cells. These genetic codes consist of paired alleles and often fall into three categories: homozygous dominant (BB), Homozygous recessive (bb), and Heterozygous (Bb). Phenotypes are the physical expression of genotypes, for example, whether someone has freckles vs. if someone does not have freckles. Just like all

    recessive alleles. Dominant and recessive alleles are straightforward. Dominant alleles are the stronger genes and expressed in the offspring while recessive alleles are the weaker genes and require all other alleles to be recessive in order to be expressed. On the other hand, when it comes to incomplete dominance and codominance, there is no distinct or simple trait that masks the other. In the case of incomplete dominance, a non-Mendelian principle by Carl Corren, the incompletely dominant alleles from

  • Mendel's Law Of Segregation Analysis

    1642 Words  | 7 Pages

    An explanation of Mendel's law of segregation Gregor Mendel was an Austrian monk in the 19th century. He experimented with pea plants to try figure out how heredity traits are passed on. He crossed several different types of pea plants with distinctive traits. One example is he crossed a true breeding pea plant with green pod color and a true breeding pea plant with yellow pod color. The resulting generation had an offspring, with a one hundred per cent growth, of pea plants with green pod color

  • Comparison: Abe Lincoln And Solar Fire

    714 Words  | 3 Pages

    To replicate the situation where Abe Lincoln and Solar Fire produce an offspring with all the desired traits, however, would involve numerous factors. Firstly, it would rely on the desired alleles of each desired trait being dominant over the non-desired trait. In doing so, incomplete or codominance would have to be factored out. Furthermore, the only way to reliably create the ideal tomato hybrid would have to be if each trait was crossed with the corresponding parent’s trait in a monohybrid cross

    relationship. Describe the eugenic and dysgenic effects of medical genetics. A basic understanding eugenics and dysgenics is that, eugenic leads to genetically healthier population, while dysgenics promotes a population carrying mutant hazardous alleles. As Francis Galton said, Eugenics is the improvement of the population by ‘selection’ of its best specimens for breeding. There are two major difficulties involved in planning a eugenics program: The scientific problem of determining which characteristics

By examining the allelic frequency in coastal and interior populations, some alleles appearing in one population with high frequencies do not exist or have low

  • Nocturnal Worms Case Study

    917 Words  | 4 Pages

    1. There are 2 types of worms: worms that eat at night (nocturnal) and worms that eat during the day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time. Each spring when the worms reproduce, they have about 500 babies but only 100 of these 500 ever become old enough to reproduce. a. What worm has natural selection selected AGAINST? diurnal worms FOR? nocturnal worms b. Darwin 's 5 points: Identify

  • Drosophila Life Cycle

    1426 Words  | 6 Pages

    Drosophila is a genus of small flies, belonging to the family Drosophilidae, whose members are often called “fruit flies”. One species of Drosophila in particular D.melanogaster, has been heavily used in research in genetics and is a common model organism in developmental biology. The entire genus, however, contains about 1,500 species and is very diverse in appearance, behavior, and breeding habitat. Scientists who study Drosophila attribute the species’ diversity to its ability to be competitive

    Noonan Syndrome Having a family member or child with an uncommon condition can be pretty extreme. When it comes to these conditions, they are usually some sort of mutation or run in the family 's genetics. Noonan Syndrome is a rare condition that affects an individual 's physical appearance, mental state, and genetic makeup, but varies in each affected person. In 1963, Noonan Syndrome was first described by a heart-specialist, Jacqueline Noonan. Of course, the condition will most likely involve
