a. Is this problem an incomplete dominance or codominance problem? b. Show the cross, Punnet square, genotypic ratio, and phenotypic ratio for a cross between a red bull and a white cow. b. Cross two roan colored cattle. Show your work and ratios.

Incomplete dominance is the blending of alleles, resulting in a phenotype that is in between the two extremes. If this was an example of incomplete dominance, we would see corn with an intermediate color (such as light yellow) rather than corn that has mixed kernels.

5 practice problem Assume that a plant shows incomplete dominance when inheriting its flower color. What is the expected phenotypic ratio of the F 2 generation when two F 1 hybrids (Rr) are crossed?

Directions: For each of the following problems, complete the Punnett Square provided and fill in the information requested. The first problem is done for you. A. In fruit flies, a black body (B) is completely dominant over gray bodies (b.) Cross a homozygous black fly with a gray fly. What are the genotype and phenotype ratios that result? B.

Red and white hair color in cows can exhibit codominance. This means some hairs are red colored and other hairs are white colored. This sometimes gives the look of a mixture, but if individual hairs are analyzed they are only red or white, not pink. When a cow has both red and white hairs its color is referred to as roan. a.

Co-dominance is observed in tabby cats. A cross between a black cat and a tan cat produces a tabby pattern (black and tan fur together). a. Cross a black cat with a tabby cat. What are the phenotypes and genotype ratios of the offspring? b. Is it possible to get a black cat if the parent generation is a tan cat crossed with a tabby cat? If you ...

Practice problems that illustrate the difference between codominance and incomplete dominance. Students are given traits to determine what type of inheritance is occurring and perform genetic crosses using punnett squares.

Incomplete Dominance Problems . 1. In snapdragons, flower color is controlled by incomplete dominance. The two alleles are red (R) and white (w). The heterozygous genotype is expressed as pink. a. What is the phenotype of a plant with the genotype RR? _____ b. What is the phenotype of a plant with the genotype ww? _____ c.

This worksheet gives you practice in problems dealing with incomplete dominance. Below is a complete example for you to follow. Important information: With incomplete dominance R' is used to denote the recessive allele. Notice the tick-mark above the R. It is used so that you can tell which kind of dominance is present in the alleles.

CODOMINANT/INCOMPLETE DOMINANCE PRACTICE WORKSHEET 1. Explain the difference between incomplete and codominance. Co-Dominance Problems 2. In a certain fish, blue scales (BB) and red scales (bb) are codominant. When a fish has the hybrid genotype, it has a patchwork of blue and red scales. (Use the letter B) a. What is the genotype for blue fish ...
