What do the letters on the top and side of a Punnett square represent?

Back

The possible alleles given by the parents following meiosis.

Front

What is a phenotype?

Front

What is the definition of homozygous dominant?

Back

An organism with two identical dominant alleles (e.g., AA).

Front

What is the definition of heterozygous?

Back

An organism with two different alleles for a trait (e.g., Aa).

Front

What does a Punnett square illustrate?

Back

The possible genetic combinations of offspring from two parents.

Front

What is the definition of genotype?

Back

The genetic makeup of an organism, represented by alleles.

Front

What is the difference between dominant and recessive alleles?

Back

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