Monohybrid Cross
A monohybrid cross is when the offspring of homozygous parents that only differ
on a single trait are bred to come up with the second generation. An example of
a monohybrid cross would be crossing two animals whose parents are large and
small. The result would be a ratio of 3:1 with more of the offspring exhibiting
the dominant trait.

Dihybrid Cross
A dihybrid cross is pretty similar to a monohybrid cross except that the parents
of the first generation differ in two traits. An example of a dihybrid cross would
be breeding the offspring of two animals; one of which is large and fat while the
other is small and lean. The resulting ratio would be 9:3:3:1 with 9 exhibiting two
dominant traits, 6 exhibiting one dominant and one recessive trait, and only one
exhibiting both recessive traits.
