What is Non-Mendelian Inheritance?

Back

Non-Mendelian inheritance refers to patterns of inheritance that do not follow Mendel's laws of segregation and independent assortment. It includes incomplete dominance, codominance, polygenic inheritance, and others.

Front

Define 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 is Codominance?

Back

Codominance is a form of inheritance where both alleles in a heterozygote are fully expressed, resulting in a phenotype that shows both traits.

Front

What is Polygenic Inheritance?

Back

Polygenic inheritance is when multiple genes influence a single trait, leading to a continuous range of phenotypes.

Front

Example of Incomplete Dominance.

Back

A red flower (RR) and a white flower (WW) produce pink flowers (RW).

Front

Example of Codominance.

Back

A black chicken (BB) and a white chicken (WW) produce speckled offspring (BW).

Front

What is Pleiotropy?

Back

Pleiotropy occurs when one gene influences multiple phenotypic traits.

Front

What are Linked Genes?

Back

Linked genes are genes that are located close to each other on the same chromosome and tend to be inherited together.

Front

Define the term 'Allele'.

Back

An allele is a variant form of a gene that can produce different traits.

Front

What is a Genotype?

Back

A genotype is the genetic constitution of an individual, represented by the alleles they possess.
