incomplete dominance and codominance problems.pdf

Name: _________________________Incomplete Dominance1. In a certain type of flower, color is incompletely dominant. Cross a pure purple flower with a pure whiteflower. What will be the phenotype of the offspring? (Don't forget that with incomplete and codominanceproblems, two different letters are used to represent the different alleles...)Offspring phenotype:2. In flowers, color is an incomplete dominance trait. (see above problem) When the genotype is heterozygous,the phenotype is lavender (a lighter shade of purple). (*In other words, if you choose LL as the genotype forlavender, you are WRONG... Use the same letters as the above problem.) Cross a lavender flower with alavender flower. What will be the genotype and the phenotype of the offspring?2a. Offspring genotypes AND probabilities:2b. Offspring phenotypes AND probabilities:3. In humans, you can have curly hair, straight hair, or wavy hair. Cross a wavy haired person with a straighthaired person and show the probabilities of the different phenotypes for that cross. Then, cross a wavy hairedperson with a wavy haired person and predict the phenotypes and probabilities for their offspring.Part 1: the phenotypes and probabilitiesof the offspring:Part 2: the phenotypes and probabilitiesof the offspring:

Codominance1. In a certain type of flower, color is codominant. Cross a pure orange flower with a pure red flower. What willbe the phenotype of the offspring? (Don't forget that with incomplete and codominance problems, two differentletters are used to represent the different alleles...)Offspring phenotype:2. In horses, white and gray color are codominant. You have a female horse that is white and gray in color. Shemates a male horse that is just gray. What are the possible outcomes of this cross?2a. Offspring genotypes AND probabilities:2b. Offspring phenotypes AND probabilities:3. Scale type in fishes is a codominant trait. Some fish have scales that all have rounded edges. Some fish havescales that all have squared edges. Some will have a mix of the two types of scales. What phenotypes will beproduced if two fish that each have a mix of scales mate (fill in this for Part 1)? What phenotypes will beproduced.if a square-scaled fish mates with a fish that has a mix of scale types (fill in this for Part 2)?Part 1: the phenotypes and probabilitiesof the offspring:Part 2: the phenotypes and probabilitiesof the offspring:
