Codominance vs incomplete dominance

Front

What is codominance?

Back

Codominance is a genetic scenario where both alleles in a heterozygous individual contribute equally and visibly to the phenotype. For example, in a flower with red and white alleles, the offspring may have both red and white petals.

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic situation where one allele does not completely dominate the other, resulting in a phenotype that is a blend of both alleles. For example, crossing red and white flowers may produce pink flowers.

Front

What is the phenotype of a plant with genotype TT?

Back

The phenotype of a plant with genotype TT is tall.

Front

What is the phenotype of a plant with genotype SS?

Back

The phenotype of a plant with genotype SS is short.

Front

If a tall plant (TT) is crossed with a short plant (SS), what is the genotype of the offspring?

Back

The genotype of the offspring will be TS.

Front

In a Punnett square showing incomplete dominance, if the genotypes are CC (curly) and SS (straight), what is the phenotype of the offspring?

Back

The phenotype of the offspring will be wavy (CS).

Front

What percentage of offspring will be gray if incomplete dominance is shown in a cross resulting in black, white, and gray cats?

Back

50% of the offspring will be gray.

Front

What percentage of offspring will be white if incomplete dominance is shown in a cross resulting in black, white, and gray cats?

Back

0% of the offspring will be white.

Front

If both parents have wavy hair (SC), what percentage of their children will also have wavy hair?

Back

50% of their children will have wavy hair.

Front

What is an example of codominance in animals?

Back

An example of codominance is a red cow and a white cow producing offspring that have both red and white patches.
