Front

What is a Punnett Square?

Back

A diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles.

Front

Define genotype.

Back

The genetic constitution of an individual, represented by the alleles inherited from parents.

Front

Define phenotype.

Back

The observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What is incomplete dominance?

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype.

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed, resulting in a phenotype that shows both traits.
