If Parent 1 Ty crosses with Parent 2 Ty what percentage of offspring will display the recessive trait?

If both Parent 1 Ty and Parent 2 Ty are heterozygous for a trait (Tt), then there is a 25% chance that their offspring will display the recessive trait (tt). If one or both parents are homozygous dominant (TT), the percentage of offspring showing the recessive trait will be 0%. The exact percentage depends on the genotypes of the parents.
