Question

What are dominant and recessive allels

Answer 1

They are what gives a person his/her features
Dominant allels are going to be there for sure.
Recessive allels aren't going to be there for sure, but can come out and show.

Answer 2

Dominant alleles are the genes the person or thing will more likely have
Recessive is the genes that are less likely to be passed on but still very much possible. I hope this helps you out :)
