Non-Mendelian Genetics Flashcardziz Test Review

Front

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, codominance, multiple alleles, and polygenic inheritance.

Front

Define Incomplete Dominance.

Back

Incomplete Dominance is a genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype that is a blend of the two.

Front

What is Codominance?

Back

Codominance 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.

Front

What are Multiple Alleles?

Back

Multiple Alleles refer to the presence of more than two alleles for a genetic trait, allowing for a variety of phenotypes.

Front

Define Polygenic Inheritance.

Back

Polygenic Inheritance is a type of inheritance where multiple genes determine the phenotype of a trait, often resulting in a continuous range of phenotypes.

Front

What is a carrier in genetics?

Back

A carrier is an individual who has one copy of a recessive allele that does not manifest in the phenotype but can be passed to offspring.

Front

What genotype represents a male with hemophilia?

Back

X^hY.

Front

What is the probability of producing a white (WW) cow from a roan (RW) bull and a red (RR) cow?

Back

0%.

Front

What percentage of female offspring will be carriers for a recessive disease if the mother is a carrier and the father is affected?

Back

50%.

Front

What is the phenotype of a roan bull?

Back

The phenotype of a roan bull is a mix of red and white fur, resulting from incomplete dominance between the red (RR) and white (WW) alleles.
