As seen in the photo, Labradors come in three colors-- black, brown and yellow. What is the genetic basis for these different coat colors? One gene produces melanin, a pigment which is deposited in the dog's fur and makes the color dark. With this gene, allele B (black) is dominant to allele b. Only in the case of a recessive homozygote (bb) will the dog's phenotype be brown. The regulatory gene is separate from the melanin gene but it acts as a switch, either turning the melanin gene on or turning it off. Allele E is dominant and allows for the melanin to be deposited in the dog's fur ("on" switch), but if the switch gene is a recessive homozygote, the melanin is blocked ("off" switch) and a yellow dog is the result! 1. Two other Labradors mate and produce puppies. Their genotypes are Bbee and BbEe. What color are each parent and what are the phenotypic rations of their offspring in the F1 Generation? Show your work with a Punnett square.

Review the information on Labrador retrievers above. What are the phenotypic ratios of the F1 generation offspring of two dihybrids? Make sure to match the numbers with coat colors (e.g, which number in the ration goes with which color). Use a Punnett square to…

With regard to the ABO blood types in humans, determine the genotypes of the individuals below: John: John is blood type A and his mom was type B Genotype = Jane: Jane is blood type B and her dad was type O Genotype John and Jane have kids. What are the possible blood types of their offspring, including the expected ratio of each? O John is A1", Jane is l'i, the blood type ratios of their children would be: 1 AB: 1A : 1B John is IA, Jane is l1", the blood type ratios of their children would be: 1 AB: 1 B John is 1Ai. Janc is iP1P, the blood typc ratios of their children would be: 1 AB: 1 A: 1B John is Jane is IPi, the blood type ratios of their children would be 1 AB : 1A 1B:10
