Question

C13. Lets suppose that weight in a species of mammal is polygenic, and each gene exists as a heavy and light allele. If the allele frequen- cies in the population are equal for both types of alleles (i.e., 50% heavy alleles and 50% light alleles), what percentage of individu- als will be homozygous for the light alleles in all of the genes affecting this trait, if the trait was determined by the following number of genes? A. Two B. Three C. Four

Now let's use trial-and-error to see if we can figure out the inheritance pattern of this trait. For EVERY pedigree diagram below and on the following pages, label what you know about the genotype of each individual shown from the information provided in the pedigree and the assumption specified above each one. You MUST label ALL FOUR diagrams separately! Genotypes in these pedigrees...

    On the island of Notion, in the Factotum Archipelago, there lives a population of pencil bears. A portion of these bears have silky fur, and as a result, are much better surfers. The texture of the fur is determined by a single autosomal locus with two alleles: S (trait allele) and s (wild type allele). In a recent study, researched collected the values in the following table: Table 1. Counts of Pencil Bear fur style by genotype Phenotype Genotype Silky...
