In pea plants, the gene for the color of the seed has two alleles. In the following Punnett square shown
below, the dominant allele (Y) represents yellow and the recessive allele (y) represents green.
Female Plant Parent One
Phenotype = Yelow
Genotype = Yy
Male Plant Parent Two
Phenotype = Yellow
Genotype = YY
Based on the Punnett square, what percentage of offspring would be expected to have green seeds?

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
