Question

The diagram represents a dihybrid cross between two pea plants that are heterozygous for both seed color and seed shape.

What is the phenotypic ratio of the offspring?


- 1:1:1:1:2:2:2:2:4

-1:3:3:9

-1:4

-4:12

Answer 1

Answer:4:12

Step-by-step explanation:

This question already provides you with the punnet square, genotypes resulting from the cross, and phenotypes resulting from the cross. Simply count the number of green phenotypes (the green circles), and compare them to the number of yellow phenotypes (yellow circles), and you get 4 green for every 12 yellow.
