What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the genetic makeup of offspring from two parents based on their alleles.

What does 'homozygous dominant' mean?

Back

Homozygous dominant refers to having two identical dominant alleles for a trait, represented as 'AA'.

Front

What does 'homozygous recessive' mean?

Back

Homozygous recessive refers to having two identical recessive alleles for a trait, represented as 'aa'.

Front

What does 'heterozygous' mean?

Back

Heterozygous refers to having one dominant and one recessive allele for a trait, represented as 'Aa'.

What is the probability of offspring being homozygous if both parents are heterozygous?

Back

The probability is 50%.

If a Punnett Square shows 4 squares, what does that represent?

Back

It represents the possible combinations of alleles from the parents.
