Question

based on the dihybrid cross, which of the following is true?
a all offspring are dominant, wrinkled and green
b all offspring are recessive, wrinkled and green
c all offspring are a combination of dominant and recessive, green and yellow peas
d all offspring are dominant, round and yellow
(d) dihybrid cross step 2.
when the yellow round corn from generation 1 reproduce, there is significant diversity in the characteristics of the offspring.

Explanation:

The problem is about a dihybrid cross (genetics in biology). The Punnett square shows all offspring have genotype RrYy. For pea traits, R (round) and Y (yellow) are dominant, r (wrinkled) and y (green) are recessive. So Rr gives round (dominant), Yy gives yellow (dominant). Thus, all offspring are dominant (round) and yellow. Option D matches.

Answer:

D. All offspring are dominant, round and yellow
