AJH Non-Mendelian Genetics Test 24-25

Front

What are the possible phenotypes of children from a parent with genotype I^A I^B and a parent with genotype I^B i?

Back

Group A, Group B, Group AB only.

Front

What is a gene that is controlled by more than two alleles called?

Back

MULTIPLE ALLELES.

Front

What type of inheritance pattern results when a tall plant (TT) is crossed with a short plant (SS) resulting in a medium plant (TS)?

Back

Incomplete Dominance.

Front

If a color-blind woman and a color-blind man have a son, what is the probability that the son is color-blind?

Back

100%.

Front

What is the genotype for Roan color in cattle, where red coats are represented as RR and white coats as WW?

Back

RW.

Front

Define Non-Mendelian Genetics.

Back

Genetics that do not follow Mendel's laws of inheritance, including patterns like incomplete dominance, codominance, and multiple alleles.

Front

What is Codominance?

Back

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 is Incomplete Dominance?

Back

A genetic situation where one allele does not completely dominate another, resulting in a phenotype that is a blend of both alleles.

Front

What is the significance of X-linked traits?

Back

X-linked traits are associated with genes on the X chromosome, often affecting males more severely due to their single X chromosome.

Front

What does it mean for a trait to be recessive?

Back

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