Back

AA

Front

What is the definition of a dominant allele?

Back

An allele that expresses its trait even in the presence of a recessive allele.

Front

What is a recessive allele?

Back

An allele that only expresses its trait when two copies are present.

Front

What is the purpose of a Punnett square?

Back

To predict the genotypes and phenotypes of offspring from a genetic cross.

Front

What does it mean to be homozygous?

Back

Having two identical alleles for a particular gene.

Front

What does it mean to be heterozygous?

Back

Having two different alleles for a particular gene.
