male genotype TtAa

female genotype TtAa

what would punnet square look like?

male genotype TtAa

female genotype TTAa

what would their punnet square look like?

disregard first part

Answer 1

Second part :-

Male parent = TtAa.
Gametes from male parent = 4 type gametes (TA, Ta, tA and ta).

Female parent = TTAa.
Gametes from female parent = 2 type gametes (TA and Ta).

Now put male gametes to top of square and female gametes to side of square.

Genotype ratio =
TTAA: TTAa: TtAA: TTaa: TtAa: Ttaa
1:2:1:1:2:1.

For first part =
Gamete types from both male and female parent = TA, Ta, tA and ta.
