Genetics Review

Front

What is a homozygous dominant genotype?

Back

A genotype consisting of two identical dominant alleles, such as RR.

Front

What is a homozygous recessive genotype?

Back

A genotype consisting of two identical recessive alleles, such as rr.

Front

What does a Punnett square predict?

Back

It predicts the possible results of a genetic cross.

Front

What is incomplete dominance?

Back

A genetic situation where the heterozygous genotype results in a phenotype that is a blend of the two homozygous phenotypes.

Front

What is co-dominance?

Back

A genetic situation where both alleles in a heterozygous genotype are fully expressed, resulting in a phenotype that shows both traits.

Front

Who is known as the 'Father of Genetics'?

Back

Gregor Mendel.

Front

What is 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, determined by its genotype.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their traits even in the presence of a recessive allele, while recessive alleles only express their traits when paired with another recessive allele.

Front

What is a heterozygous genotype?

Back

A genotype consisting of two different alleles, such as Rr.
