What is the difference between mono-hybrid and di-hybrid?

In: Genetics, Hybrid Cars [Edit categories]

Answer:

A mono-hybrid cross occurs when each parent has a different allele for the same trait, as in tall (T) and short (t) for height. This results in the 1:2:1 or 1TT:2Tt:1tt genotypic segregation ratio in the F2 if the offspring is allowed to self. A di-hybrid results when each parent differs from the other for alleles of two traits. If a di-hybrid F1 is allowed to self, the normal genotypic ratio in the F2 population will be 9:3:3:1, or 9AABB:3A_bb:3aaB_:1aabb.
