Non-Mendelian Genetics Practice

What is Non-Mendelian Genetics?

Back

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

Front

What is Incomplete Dominance?

Back

Incomplete Dominance is a type of inheritance where the phenotype of a heterozygote 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

What is Epistasis?

Back

Epistasis is a genetic interaction where one gene masks or suppresses the expression of another gene.

Front

What is a Sex-Linked Trait?

Back

A Sex-Linked Trait is a trait associated with a gene that is carried only by the male or female parent, often located on the X or Y chromosome.

What is the probability of producing a white (WW) cow from a roan (RW) bull and a red (RR) cow?

Back

0%.

What is the probability that sons of a colorblind woman and a man with normal vision will be colorblind?

Back

100%.

Front

What inheritance pattern is represented by a trait that shows both parental phenotypes equally in the offspring?

Back

Codominance.
