Incomplete and Codominance

Front

The different forms of a gene are called ---

Back

alleles

Front

Codominance occurs in calico cats, which allows for the Black and Tan colors to show. What percentage of the offspring represented in this P square will be calico (black and tan spotted)?

Back

50%

Front

An allele whose trait only shows up when no dominant allele is present is called?

Back

recessive allele

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

Incomplete dominance occurs in cats, which allows them to be Black, White, or gray. What percentage of the offspring will be black?

Back

50%

Front

What is the definition of 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 new phenotype that is a blend of the two.

Front

What is a Punnett square used for?

Back

To predict the genotypes and phenotypes of offspring from a genetic cross.

Front

What is the phenotype of a plant with genotype RW in a case of incomplete dominance?

Back

Pink flowers.

Front

If a plant with genotype RR is crossed with a plant with genotype WW, what will be the genotype of the offspring?

Back

All RW.
