4. For Labrador retrievers, black fur color (B) is dominant to yellow fur color (b). If a heterozygous black male mated with a homozygous yellow female, what would the puppies look like? Determine the phenotypic ratios. • Step 1: Determine the genotype of the female and male Labradors. Heterozygous black male:, Homozygous yellow female: • Step 2: Write/Type the cross between the two Labradors. Melosis Activity BIOL 101 Step 3: Do a Punnett Square to determine the probable genotypes for the offspring and to determine the Thenotypic ratio. Step 4: Determine the Phenotype ratios of the progeny: 5. There are many humans traits that are fairly simple and that follow the Mendelian pattern of inheritance. However, most of our traits are much more complex, Involving many genes or interactions between genes. For example, hair color is determined by at least four genes, each one coding for the productions of melanin, a brown pigment. Because the effect of these genes is cumulative, hair color can range from blonde (little melanin) to very dark brown (much melanin), Human traits are of great interest to us and there are few traits that seem to exhibit Mendelian Inheritance such as the ones shown below (this can be found in your lab manual),
