What is Nonmendelian Genetics?

Back

Nonmendelian Genetics refers to patterns of inheritance that do not follow Mendel's laws of inheritance, including incomplete dominance, codominance, multiple alleles, and polygenic inheritance.

Front

What is Incomplete Dominance?

Back

Incomplete Dominance is a type of inheritance where the phenotype of heterozygotes is intermediate between the phenotypes of the two homozygotes.

Front

What is Codominance?

Back

Codominance is 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 are Multiple Alleles?

Back

Multiple Alleles refer to the presence of more than two alleles for a genetic trait within a population.

Front

What is Polygenic Inheritance?

Back

Polygenic Inheritance is a type of inheritance where multiple genes influence a single trait, resulting in a continuous range of phenotypes.

Front

Define Homozygous.

Back

Homozygous refers to having two identical alleles for a particular gene (e.g., AA or aa).

Front

Define Heterozygous.

Back

Heterozygous refers to having two different alleles for a particular gene (e.g., Aa).

Front

What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the genotypes of a particular cross or breeding experiment.

Front

What is the genotype of a parent that can produce both dominant and recessive alleles?

Back

The genotype is heterozygous (e.g., Bb).

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.
