A. the alleles segregate during meiosis. Mendel first proposed that alleles segregate from one another during the formation of gametes. B. each allele contains two mutations. This choice is not relevant to the problem, because the relationship between the mutation and phenotype is not given. C. the alleles are identical.

WebMeiosis I reduces the number of chromosome sets from two to one. The genetic information is also mixed during this division to create unique recombinant chromosomes. Meiosis II, in which the second round of meiotic division takes place in a way that is similar to mitosis, includes prophase II, prometaphase II, and so on.

Meiosis involves two successive stages or phases of cell division, meiosis I and meiosis II. Each stage includes a period of nuclear division or karyokinesis and a cytoplasmic division or cytokinesis.
