What is the definition of homozygous?

Back

An organism is homozygous when it has two identical alleles for a trait.

Front

What is the definition of a dominant allele?

Back

A dominant allele is one that expresses its trait even when paired with a different allele.

Front

What is the definition of a recessive allele?

Back

A recessive allele is one that only expresses its trait when paired with another recessive allele.

Front

What is a Punnett square used for?

Back

A Punnett square is used to predict the genetic outcomes of a cross between two organisms.

Front

What does the term 'genotype' refer to?

Back

Genotype refers to the genetic makeup of an organism.
