Quiz about Non - Mendelian Genetics

Question 1

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?

Accepted Answer

Non - Mendelian Inheritance

Answer

Mendelian Inheritance

Answer

Incomplete Inheritance

Answer

Codominant Inheritance

Question 2

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?

Accepted Answer

Incomplete Dominance

Answer

Codominance

Answer

Complete Dominance

Answer

Failed Dominance

Question 3

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

Accepted Answer

Answer

Complete Dominance

Answer

Incomplete Dominance

Answer

Failed Dominance
