Chapter 3, Problem 7PDQ

When working out genetics problems in this and succeeding chapters, alwaysassumethatmembersof the P₁ generation are homozygous, unless the information or data you are given require you to do otherwise.

Mendel crossed peas having round seeds and yellow cotyledons with peas having wrinkled seeds and green cotyledons. All the F₁ plants had round seeds with yellow cotyledons. Diagram this cross through the F₂ generation, using both the Punnett square and forked-line methods.
