What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even if only one copy is present, while recessive alleles require two copies to express their trait.

Front

What is the principle of segregation in genetics?

Back

The principle of segregation states that during the formation of gametes, the two alleles for a trait separate from each other.
