A recessive trait.
It is not dominant.
Both alleles are the same.
It can be dominant or recessive.
The alleles are different.
The prefix of this word means "different"
How many alleles are there for blood type and what are they?

The prefix of this word means "many"
A chart used to follow a genetic trait from generation to generation.
A brand of dog food
