#Unit 8. Inheritance Biology

The interaction of two loci that determine fruit color in summer squash, which is commonly found in one of three colors: yellow, white, or green. When a homozygous plant that produces white squash is crossed with a homozygous plant that produces green squash and the F1 plants are crossed with each other, the following results are obtained:

 12/16 plants with white squash

 3 /16 plants with yellow squash

 1 /16 plants with green squash

 This is the case of___
