In garden peas, yellow seeds (Y)(Y) are dominant to green seeds (y)(y), and inflated pods (I)(I) are dominant to constricted pods (i)(i). Suppose you have crossed YYIIYYII parents with yyiiyyii parents.What are the gametes and f1 offspring? And what is a diagram of the punnet squares.

What is the cross between the progeny of F1 and the homozygous reccessive parent called? How is it usefull?

In fruit flies, chromosomal crossing over does not occur in meiosis in males, whereas crossing over does occur in meiosis in females. In fruit flies that are heterozygous at many genes (i.e. many maternal and paternal versions of the genes differ), at what stage would cells no longer be heterozygous for any gene during the process of meiosis? a)After the second meiotic division in males, and after the first meiotic division in females. b)After the second meiotic division in both males and females. c)After the first meiotic division in both males and females. d)After the first meiotic division in males, and after the second meiotic division in females.
