Non-Mendelian Genetics

What is Non-Mendelian Genetics?

Back

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

Front

What is incomplete dominance?

Back

Incomplete dominance is a type of inheritance where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes, resulting in a mixture of traits.

Front

What is co-dominance?

Back

Co-dominance 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 are the male sex chromosomes?

Back

The male sex chromosomes are XY.

Front

What are the possible phenotypes of a child from parents with genotypes I^AI^B and I^Bi?

Back

The possible phenotypes are Group A, Group B, and Group AB.

Front

What is a pedigree chart?

Back

A pedigree chart is a diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism and its ancestors.

Front

What does it mean if a trait is recessive?

Back

A recessive trait is one that is expressed in the phenotype only when two copies of the recessive allele are present.

Front

How many alleles are involved in codominant and incompletely dominant traits?

Back

Two alleles are involved in codominant and incompletely dominant traits.

Front

What is the genotype of a father with a recessive trait for blue eyes?

Back

The genotype of the father is Aa.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable characteristics or traits of that organism.
