Nonmendelian Genetics

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 traits.

What are dominant alleles represented by?

Back

Dominant alleles are represented by a capital letter.

Front

What is a homozygous dominant genotype?

Back

A homozygous dominant genotype consists of two identical dominant alleles, represented as 'AA'.

Front

What is the genotype of offspring from two O blood type parents?

Back

The genotype of the offspring will be 100% OO.

Front

What is the result of crossing two pink (RW) flowers?

Back

The offspring will have 50% pink (RW), 25% white (WW), and 25% red (RR).

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 is incomplete dominance?

Back

Incomplete dominance is a form of inheritance where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.

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 a phenotype?

Back

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

Front

What is a genotype?

Back

A genotype is the genetic constitution of an individual, specifically the alleles present at a given locus.
