Front

What is a recessive allele?

Back

A recessive allele is an allele that only expresses its trait when two copies are present (homozygous).

Front

What is the law of segregation?

Back

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

Front

What is the law of independent assortment?

Back

The law of independent assortment states that alleles for different traits are distributed to gametes independently of one another.
