Non - Mendelian Genetics

In Genetics, different characteristics may be controlled by one gene with two alleles and may have a codominant or incompletely dominant relationship. What do you call these phenomenon?

• Mendelian Inheritance

• Incomplete Inheritance

• Codominant Inheritance

• Non - Mendelian Inheritance

A completely dominant allele does not occur when the phenotype of a heterozygote offspring is somewhere in between the phenotypes of both homozygous parents. What type of dominance is this?

• Incomplete Dominance

• Codominance

• Complete Dominance

• Failed Dominance

What occurs when both alleles are expressed equally in the phenotype of the heterozygote?

• Complete Dominance

• Codominance

• Incomplete Dominance

• Failed Dominance

The reddish-brown and white coat color in the example above has codominant alleles for reddish-brown coat color and white coat color in cows. Basing on the Genotypic Punnett Square, predict the color of coat of the cow in the blank space.

• Reddish - Brown

• White

• Brown

• Red
