Polygenic inheritance is the condition where the character is controlled by the effect of more than one gene. Introduction. The different forms of an allele in two organisms of the species can result in changes in their appearance even though their genetic composition is highly similar. These are gene polymorphisms that account for the change in the appearance of genetically similar organisms.

Using designations "Group A", “Group B," etc., organize the mutant strains into complementation groups. If the result of any cross does not fit your groupings, indicate which cross(es) you have excluded. Consider the consequence if one of the mutations was dominant. You should see that complementation tests could not be used to provide information about dominant mutations. a) If a mutation were dominant, how would the diploid be affected? What effect would this have on the determination of your complementation groups? b) How would you test if any of these trp¯ mutations were dominant?

EC2. Here is a tetrad produced by mating a H Y strain to an h y strain. a) What is the tetrad type? b) What has recombined with what? EC3. In corn, a dihybrid for the recessive genes a and b is test-crossed. The distribution of the phenotypes is as follows: A B 122A b 118a B 81a b 79 a) Do the genes appear to be sorting independently? Look at map units here. b) Test your hypothesis with a chi-squared test.

Multiple crosses were made between true-breeding lines of black and yellow Labrador retrievers. All the F1 progeny were yellow. When these progeny were intercrossed, they produced an F2 consisting of 121 yellow, 9 black and 30 chocolate. What epistatic ratio and what kind of epistasis is approximated in the F2? Propose a biochemical pathway for coat color in Labrador retrievers based on the type of epistasis. Correlate each genotype with the phenotype that would occur in your pathway. Also show the frequency of each genotype. A-B- A-bb aaB- aabb
