A dihybrid cross is created from plants that are heterozygous for both round seeds and yellow seed color. What is the ratio of offspring that have round seeds and yellow seed color? 1:16
3:16
9:16
16:16

The ratio of offspring that have round seeds and yellow seed color in a dihybrid cross is 9 out of 16.

WHAT IS A DIHYBRID CROSS:

• A dihybrid cross is a cross between two individuals that are are heterozygous for two genes.

• In this question, a gene involving seed color and seed shape is used. The allele for round shape (R) and yellow seeds (Y) are dominant over wrinkled (r) and green seeds (y).

A cross between two dihybrid i.e. RrYyx RrYy will result in the following offsprings:

R_Y_-9

R_yy - 3 rrY_ - 3

rryy - 1

Therefore, the ratio of offspring that have round seeds and yellow seed color in a

dihybrid cross is 9 out of 16.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
