Punnett Squares

Front

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 does the term 'phenotype' refer to?

Back

Phenotype refers to the observable physical characteristics or traits of an organism, such as hair color or height.

Front

What is the difference between homozygous and heterozygous?

Back

Homozygous means having two identical alleles for a trait, while heterozygous means having two different alleles for a trait.

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

How can you determine the probability of a trait being passed down?

Back

You can determine the probability of a trait being passed down by using a Punnett Square.

Front

What is the genotype for a homozygous dominant individual?

Back

The genotype for a homozygous dominant individual is represented as 'AA'.

Front

What is the genotype for a homozygous recessive individual?

Back

The genotype for a homozygous recessive individual is represented as 'aa'.

Front

What is the genotype for a heterozygous individual?

Back

The genotype for a heterozygous individual is represented as 'Aa'.

Front

What is the purpose of using a Punnett Square?

Back

The purpose of using a Punnett Square is to visualize and calculate the probability of different genotypes and phenotypes in offspring.
