What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles from the parents.

Front

What do the letters in a Punnett Square represent?

Back

The letters represent different alleles of a gene, where uppercase letters indicate dominant alleles and lowercase letters indicate recessive alleles.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the combination of alleles (e.g., AA, Aa, aa).

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What does 'dominant' mean in genetics?

Back

A dominant allele is one that expresses its trait even when only one copy is present in the genotype.

Front

What does 'recessive' mean in genetics?

Back

A recessive allele is one that only expresses its trait when two copies are present in the genotype.

Front

What is the purpose of a Punnett Square?

Back

The purpose of a Punnett Square is to predict the probability of an offspring inheriting particular traits from its parents.
