Adiploid somatic ("body") cell has 2n = 20 chromosomes. at the end of mitosis, each daughter cell would have chromosomes. at the end of meiosis i, each daughter cell would have chromosomes. at the end of meiosis ii, each daughter cell would have chromosomes.
a. 2n = 20, 2n = 20, 1n = 10
b. 2n = 20, 2n = 10, 1n = 10
c. 1n = 10, 1n = 10, 1n = 10
d. 2n = 20, 2n = 20, 1n = 20
e. 2n = 20, 1n = 10, 1n = 10

e. 2n = 20, 1n = 10, 1n = 10

Explanation:

When a cell undergoes mitosis it divides into two daughter cells, each identical to the original. For that reason, a diploid cell with 20 chromosmoes (2n = 20) will produce two identical daughter cells after mitosis.

During meiosis I the homologous chromosomes separate and the daughter cells become haploid (only one set of each chromosome) and with half the original chromosome number (n=10). Each chromosome has 2 chromatids.

During meiosis II the two chromatids of each chromosome separate, but the daughter cells remain haploid and with the same chromosome number.

the genotypes would be 50% bb and 50% bb

the phenotypes would be 50% brown and 50% white. hope this : )
