What do we call a trait that is apparent only when two recessive alleles for the same characteristic are inherited?

Front

What is a recessive allele?

Back

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

What is the purpose of a Punnett square?

Back

A Punnett square is used to predict the genotypes and phenotypes of offspring from a genetic cross.
