Front

When one allele is not dominant over the other, resulting in both traits expressed in a heterozygous individual, what is this called?

Back

Codominance

Front

What is a segment of DNA that codes for a particular protein, leading to a particular trait?

Back

Gene

Front

What is the definition of an allele?

Back

An allele is a variant form of a gene that can produce different traits.

Front

What is the principle of segregation in genetics?

Back

The principle of segregation states that during the formation of gametes, the two alleles for a trait separate from each other.

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.

Front

What is incomplete dominance?

Back

Incomplete dominance is when the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.

Front

What is polygenic inheritance?

Back

Polygenic inheritance is when multiple genes influence a single trait, resulting in a range of phenotypes.
