Front

What is the definition of a genotype?

Back

The genetic makeup of an organism, represented by alleles.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism.

Front

What does it mean to be heterozygous?

Back

Having two different alleles for a specific gene.

Front

What is the purpose of a Punnett square?

Back

To predict the probability of offspring genotypes and phenotypes from a genetic cross.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even in the presence of a different allele, while recessive alleles only express their trait when two copies are present.
