Non-mendelian review

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. Examples include incomplete dominance, co-dominance, and multiple alleles.

Front

What is the probability of a child having type O blood if both parents have type AB blood?

Back

0% - Type AB parents can only pass on A or B alleles.

Front

What is co-dominance?

Back

Co-dominance is a form of inheritance where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive. Example: A calico cat with both orange and black fur.

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. Example: Red and white flowers producing pink flowers.

Front

What are the blood type alleles and their dominance relationships?

Back

A and B are co-dominant, while O is recessive.

Front

If a trait shows incomplete dominance, what does this mean?

Back

It means that the phenotype of the heterozygote is a blend of the two parental traits.

Front

What is an example of co-dominance in animals?

Back

The coat color of a calico cat, which displays both orange and black fur.

Front

What is the expected phenotype ratio in a monohybrid cross involving incomplete dominance?

Back

1:2:1 ratio of phenotypes.

Front

How do blood types A, B, AB, and O relate to co-dominance?

Back

Blood types A and B are co-dominant to each other, while type O is recessive.

Front

What is the significance of multiple alleles in inheritance?

Back

Multiple alleles allow for more than two forms of a gene to exist in a population, leading to greater genetic diversity.
