The way in which a true breeding variety of cat can be developed and the method to determine that the curl allele is a dominant or recessive and how it can be checked if they are true breeding or not. Introduction: True breeding varieties are the parents that will produce the offspring depicting the same phenotype as they possess. This can be experimentally achieved if the individuals are bred with theindividuals of same variety. The probability of obtaining a different phenotype in offspring of two true bread varieties is zero.

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.

our sister breeds Labradors, but is unaware of the genetics of coat color, so she has been mixing and matching various breeding pairs, unable to predict the outcomes. She recently bred two black labs, expecting to get only black lab puppies, but instead, the litter included black, brown, and yellow pups. She is confused, but since you know your genetics, you can explain to her what’s going on. What are the genotypes of these two parents, for both of the genes involved? What are the possible genotypes of the various offspring? (Organize them by phenotype.) Litters of puppies are too small for reliable statistics, but if these two parents had a large number of puppies over time, what are the expected ratios (or fractions or percents) of the three possible coat colors?

"In cattle, the allele that causes horns to grow is recessive. Another recessive allele causes the cows to grow abnormally large and muscular. These muscular cows are often called Belgian blue cows. If a cow that is heterozygous for both the horn and Belgian blue trait genes passes on the allele for growing horns to an offspring, what are the odds that the parent cow also passes on the allele for becoming very muscular to that offspring?" I know the answer is 50% but how do I get to this answer?
