Assume one chromosome has A-B, and other homologous chromosome has a-b and no crossing over orccurs. (choose one answer only) 1. Ab 2. AB 3. AB,Ab,aB,ab 4. Ab,aB 5. ab 6. AB,ab 7. aBConsider a Cell that has two types of chromosomes, Chromosome 1 with gene E, and Chromosome 2 with gene D. Show the chromosomes as they would appear at metaphase of meiosis 1 and then again during metaphase of meiosis 2. label each chromosome do not need to show crossing over, or the results of crossing over.

Identify two ways that meiosis contributes to genetic recombination. Why is it necessary to reduce the number of chromosomes in gametes, but not in other cell?Which of the following terms describes the process of homologous chromosomes failing to separate correctly during meiosis?A. Chromatid adhesion syndromeB. NondisjunctionC. AmetaphasiaD. Anti-anaphaseRepresent the segregation of chromosomes during Meiosis 1 and Meiosis 2 a.) normal segregation in male b.) abnormal segregation in female Make use of circles as representing cells undergoing the above processes. Inside the circles are the chromosome number of the male or the female. Answer must be a number not a drawing.
