Question

Complete the Dihybrid cross Punnett square diagram.

TTGG, TTGg, TtGg, Ttgg, TtGG, TtGg, ttGg, Ttgg
TtGG, Ttgg, ttGG, ttgg, TtGG, Ttgg, TTGG, TTgg
TTgg, TTGG, TtGg, ttgg, TtGg, Ttgg, TtGG, TTGg
None of the above

hint Hint:

Genotype of offspring is obtained by crossing the genes present in the left column with the genes in the upper row of the Punnett square.

The correct answer is: TTGG, TTGg, TtGg, Ttgg, TtGG, TtGg, ttGg, Ttgg

In a Punnett square, the upper row represents the alleles for male gametes.

The left column represents the alleles for female gametes.

In the given Punnett square, the cross between:

TG & TG produces TTGG

TG & Tg produces TTGg

Tg & tG produces TtGg

Tg & Tg produces TTgg

tG & TG produces TtGg

tG & Tg produces TgGg

tg & tG produces ttGg

tg &Tg produces Ttgg

Hence, the correct option is TTGG, TTGg, TtGg, Ttgg, TtGG, TtGg, ttGg, Ttgg.
