Based
on their strength, there are two different types of genes, dominant
and recessive. Dominant genes are the strong genes, the ones that usually
are passed on and run in the family. Recessive genes are the ones that are
usually dropped when challenged by a dominant gene. For example, if you have
one parent with a dominant trait and the other with a recessive, you would
most likely have the dominant trait, but the pattern doesn't work all the
time! That's what's makes genetics so interesting! The red hair gene is the
only gene that can skip a generation. That means if you had a grandparent
with red hair but parents who didn't inherit it, you could still be born
with red hair! The genes of traits that don't appear on you can still be
in you,
but red hair is the only one that can present itself even when it hasn't
been visible for a generation. Here is a list of dominant and recessive
traits:
