Question

In Vampires bats, 2 teeth (T) is dominant and 1 tooth (t) is recessive. Draw a Punnett Square showing the cross between a vampire bat that is heterozygous for 2 teeth, with a vampire bat that homozygous for 1 tooth. What is the ratio (or percentages) of the genotype and phenotypes of the possible offspring 100 points yessuh

Answer 1

This cross is called Monohybrid test cross.

Crossing Homozygous Dominant and recessive Parents (TT x tt ) will Produce Heterozygous Dominant (Tt ) F1 progeny which is Hybrid

Now question is asking for to cross this Monohybrid (Tt) with recessive ( tt ) called test cross .

crossing Tt x tt will give results where

P.R = G.R = 1:1
