Non-Mendelian Genetics

Front

What do you call the physical expression of a gene?

Back

phenotype

Front

A red flowered plant (RR) breeds with a White flowered plant (WW). The gene for petal color in these plants expresses incomplete dominance. What percentage of the offspring will have pink (RW) flowers?

Back

100%

Front

The different forms of a gene are called

Back

alleles

Front

A genotype where only recessive alleles were passed on from both parents for one trait (examples: bb aa tt ll) is called:

Back

Homozygous Recessive

Front

A genotype where one dominant and one recessive allele was passed on from both parents for one trait is called: (examples: Bb Aa Tt Ll)

Back

Heterozygous

Front

When red snapdragons are crossed with white snapdragons, the offspring produce pink flowers. This is an example of: complete dominance, incomplete dominance, codominance, polygenic inheritance, multiple alleles

Back

incomplete dominance

Front

When red cows are crossed with white cows, the offspring have a mix of red hair and white hair. These cows are called roan. This is an example of: complete dominance, incomplete dominance, codominance, polygenic inheritance, multiple alleles

Back

codominance

Front

Human eye color is controlled by three different genes, and affected by a dozen more. This is an example of:

Back

polygenic inheritance

Front

The gene for human blood type has three alleles, A, B and O. This is an example of:

Back

multiple alleles

Front

This flower is produced by crossing a pink-flowering plant and a white-flowering plant. This is an example of: complete dominance, incomplete dominance, codominance, polygenic inheritance, multiple alleles

Back

codominance
