AP Biology Unit 5 Review

Front

What is incomplete dominance?

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype that is a blend of the two traits.

Front

What is complete dominance?

Back

A form of inheritance in which one allele completely masks the effect of another allele for a trait.

Front

What is a dihybrid cross?

Back

A genetic cross that examines the inheritance of two different traits, typically involving two genes.

Front

What is the expected phenotypic ratio of a dihybrid cross?

Back

9:3:3:1.

Front

What is polygenic inheritance?

Back

A type of inheritance where multiple genes influence a single trait, resulting in a range of phenotypes.

Front

What are multiple alleles?

Back

A situation in which a gene has more than two alleles, but an individual can only have two of those alleles.

Front

Who is known as the Father of Genetics?

Back

Gregor Mendel, who conducted foundational experiments with pea plants.

Front

What is epistasis?

Back

A genetic interaction where the expression of one gene is affected by one or more other genes.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits.

Front

What does homozygous mean?

Back

Having two identical alleles for a particular gene.
