In pea plants, round seeds (r) are dominant to wrinkled seeds (r), and yellow seed color (y) is dominant to green seed color (y) . the gene for seed shape and the gene for seed color follow the law of independent assortment and are not sex-linked. in a cross between two rryy parents, predict the fraction of offspring with round, yellow seeds.

a) 1/2
b) 3/4
c) 9/16
d) 15/16

answer:

b

explanation:

the dominant gene means that if there is one dominant gene in the code, it will dominate the recessive gene. so, therefore, you must get to yy or rr in order for a non-dominant gene to be passed which means rryy=dominant round yellow, rryy= round green, and so on so forth.

hope this : )

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.
