The diagram shown represents a dihybrid cross between two pea plants heterozygous for both seed color and seed shape. what is the phenotypic ratio of the offspring?
A. 1:1:1:2:2:2:2:4
B. 1:3:3:9
C. 1:4
D. 4:12

1:3:3:9

Explanation:

There are 12 yellow seeds, from which 9 are smooth and 3 are rough.

There are 4 green seeds, from which 3 are smooth and only 1 is rough.

Both the appearance and color of the seeds is something you need to look out for when dealing with phenotypes.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
