Question

What is a dominant and recessive alleles?

Answer 1

Answer: A dominant allele is a variation of a gene that produces a dominant phenotype in individuals who have just one copy of the allele, which can come from just one parent, and a recessive allele is when the individual must have two copies, one from each parent to produce a recessive phenotype, also a recessive allele is an allele that is completely masked phenotypically by a dominant allele.

Answer 2

A dominant allele is expressed over a recessive allele, the alleles show what trait you will get. If you have one dominant allele and one recessive allele, you will express that dominant allele, if you have both dominant you will have that dominant trait, if you have both recessive alleles you will express that recessive allele
