Mendelian & Non-Mendelian Genetics

Front

What is the probability of a blue-eyed child from two brown-eyed parents (Bb)?

Back

25%.

Front

What type of inheritance is represented when both alleles contribute to the phenotype equally?

Back

Codominance.

Front

What are the genotypes for red, white, and speckled carnations exhibiting codominance?

Back

Red = RR, white = WW, speckled = RW.

Front

What is the term for the physical expression of a gene?

Back

Phenotype.

Front

What do you call a genotype where only recessive alleles are present from both parents?

Back

Homozygous Recessive.

Front

What is the term for the genetic makeup of an organism?

Back

Genotype.

Front

In Mendelian genetics, what is the expected phenotypic ratio of a monohybrid cross?

Back

3:1.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles mask the effect of recessive alleles in heterozygous conditions.

Front

What is incomplete dominance?

Back

A form of inheritance where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.

Front

What is polygenic inheritance?

Back

A type of inheritance where multiple genes influence a trait.
