Nonmendelian Genetics

Front

What is a dominant allele represented by?

Back

A capital letter.

Front

What does it mean to be homozygous for a trait?

Back

Having two of the SAME alleles for a trait (e.g., HH or hh).

Front

In snapdragons, which genotype leads to a blended phenotype?

Back

Heterozygous.

Front

What term describes when two or more genes control one single trait?

Back

Polygenetic Traits.

Front

What inheritance pattern is represented by multiple alleles?

Back

Multiple Alleles.

Front

What is the definition of incomplete dominance?

Back

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

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

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 is a polygenic trait?

Back

A trait that is controlled by two or more genes.

Front

What is the significance of multiple alleles in genetics?

Back

It allows for more than two allele options for a single gene, leading to greater genetic diversity.
