Heredity and Punnett Squares

Front

What is a recessive trait in Mendelian genetics?

Back

A trait or characteristic that appears to disappear in the offspring unless both parents contribute it.

Front

How is a recessive trait represented in genetics?

Back

By a lowercase letter (e.g., t).

Front

What allele combination represents homozygous dominant?

Back

AA.

Front

What is a dominant trait in Mendelian genetics?

Back

A trait or characteristic that will appear in the offspring if one or both of the parents contributes it.

Front

What allele combination represents heterozygous dominant?

Back

Aa.

Front

Define allele.

Back

An allele is a variant form of a gene that can produce different traits.

Front

What is the purpose of a Punnett square?

Back

To predict the genetic outcomes of a cross between two organisms.

Front

What does homozygous mean?

Back

Having two identical alleles for a particular gene (e.g., AA or aa).

Front

What does heterozygous mean?

Back

Having two different alleles for a particular gene (e.g., Aa).

Front

What is the genotype?

Back

The genetic makeup of an organism, represented by alleles.
