What is a Monohybrid Cross?

Back

A genetic cross between two organisms that examines the inheritance of a single trait.

Front

What does the Law of Independent Assortment state?

Back

Genes for different traits assort independently during the formation of gametes.

Front

What is the Law of Segregation?

Back

The Mendelian law stating that organisms inherit two copies of each gene and donate one copy to each of their offspring.

Front

Explain the Law of Segregation in terms of gametes.

Back

Organisms inherit 2 copies of each gene, 1 from each parent, and only pass on 1 copy of each gene in their gametes.

Front

What is Codominance?

Back

A genetic scenario where two dominant alleles are expressed equally or fully in the phenotype.

Front

Define Allele.

Back

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

Front

What is a Dihybrid Cross?

Back

A genetic cross that examines the inheritance of two different traits.

Front

What is the difference between Dominant and Recessive alleles?

Back

Dominant alleles express their trait even when only one copy is present, while recessive alleles require two copies to express their trait.

Front

What is Polygenic Inheritance?

Back

A type of inheritance where multiple genes influence a single trait.

Front

What is Incomplete Dominance?

Back

A genetic situation where neither allele is completely dominant, resulting in a blend of traits.
