What is Non-Mendelian Genetics?

Back

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

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 alleles?

Back

Alleles are different forms of a gene that can exist at a specific locus on a chromosome.

Front

What is the phenotype ratio of offspring from a cross between RR and WW in incomplete dominance?

Back

The expected phenotype ratio is 0:1:1, meaning all offspring will show the intermediate phenotype.

What is the expected phenotype of a cross between a black chicken (BB) and a white chicken (WW) under codominance?

Back

The expected phenotype is speckled black and white.

Front

What percentage of offspring will have pink flowers when a red flowered plant (RR) is crossed with a white flowered plant (WW) under incomplete dominance?

Back

100% of the offspring will have pink (RW) flowers.

Front

What color are the flowers of a snapdragon with genotype RW?

Back

The flowers will be pink.

Front

What is a hybrid?

Back

A hybrid is the offspring resulting from the crossbreeding of two different species or varieties.

Front

What is a trait?

Back

A trait is a specific characteristic of an organism, which can be influenced by genetics.
