Non-Mendelian Inheritance

These flashcards cover key concepts related to non-Mendelian inheritance as discussed in the lecture.

Non-Mendelian inheritance

Phenotype expression that is not solely the result of dominant and recessive alleles.

Continuous variation

Traits that can show a range of small differences due to the influence of multiple genes.

Polygenic inheritance

Inheritance pattern where multiple genes influence a single trait.

Pleiotropic inheritance

Inheritance where one gene causes multiple variations of phenotype.

Incomplete dominance

Inheritance pattern where heterozygous individuals exhibit a phenotype that is a blend of both alleles.

Codominance

Inheritance pattern where both alleles are fully expressed in the phenotype of heterozygotes.

Epistasis

Genetic interaction where the phenotype of one gene is dependent on one or more modifier genes.

X-linked traits

Traits determined by genes located on the X chromosome, often exhibiting different patterns in males and females.

Linkage

The tendency of genes located close together on a chromosome to segregate together during meiosis.

Heat-sensitive alleles

Alleles that express different phenotypes in response to temperature changes.
