1. Compare and contrast mitosis and meiosis.
Mitosis and Meiosis both include splitting DNA between new cells. They both include cell reproduction which contains chromosomes from both parents. In Mitosis the two daughter cells are identical from a single parent cell. Mitosis produces the most cells in the body. In Meiosis the daughter cells are not identical and splits the chromosomes in half which produces gametes. This makes the cells identity unique.

2. What major event occurs during interphase?
DNA replication is the major event that occurs at the completion of the three phases in the interphase.

iii. Daughter Cell from Mitosis:44

iv. Daughter Cell from Meiosis II: 44

10. Research and find a disease that is caused by chromosomal mutations. When does the mutation occur? What chromosomes are affected? What are the consequences?
Down Syndrome Disorder is caused by having three duplicates of the qualities on chromosome 21, as opposed to two. It happens because of a disappointment of the 21st chromosome to isolate amid egg or sperm improvement. Thus, a sperm or egg cell is delivered with an additional duplicate of chromosome 21, influencing this cell to have 24 chromosomes. The results of this transformation are physical development delays, trademark facial highlights and mellow to direct intellectual disability.

11. Diagram what would happen if sexual reproduction took place for four generations using diploid (2n) cells.
For each of the reproductive cycles, the diploids would divide into haploid gametes then two of the gametes would join to make a diploid. Re-occurring in each of the generations when the sexual reproduction is completed keeping the numbers of haploids and diploids the same. Experiment 2: The Importance of Cell Cycle
