A dog breeder has a female black Labrador Retriever that was one of a litter of puppies from a mating of a yellow lab with a brown lab. If he breeds this dog with a black stud that is also from a mating between yellow lab and a brown lab, what phenotypes and ratio which you expect among the puppies.

Your black labrador has a genotype of BbEe. Which of the following is correct? Select all that apply. your labrador could have had one yellow parent if he mates with a brown labrador, and ANY of pups are yellow, it means the brown labrador genotype has to be bbEe. if he mates with a yellow labrador it would be impossible to have any brown pups when he mates with a bbee labrador, the pups will be 1/4 black, 1/4 brown...

2. In Labrador dogs, there are 2 loci that determine coat color. The first locus, B is dominant to b. At least one B allele will produce black coat color, while the bb genotype produces a chocolate coat color. This first locus also determines nose color in Labradors: B_ black noses, and bb brown noses. The second locus has a genotype, ee, that is epistatic in nature. Any Labrador with an ee genotype will be yellow. A genotype containing at...

The Labrador retriever's coat colours are black, yellow, and chocolate. s produced by the presence of a recessive epistatic gene, which has the effect of masking the black and chocolate colour genes. Black (B) is dominant to chocolate (b) Therefore, the possible genotypes and corresponding phenotypes are: Phenotype Black Brown Yellow Possible Genotypes G bb 41. Predict the percentage of offspring that would be black in colour for each of the following crosses. Record your answer as a whole number....

Let's say you are studying color in labrador retrievers (a dog breed). In this breed, color is controlled by 2 genes. If you breed 2 individuals who are heterozygous for both genes together, you expect offspring to follow this ratio. 9 black : 3 chocolate : 4 yellow. Let's say you can study 40 offspring from such a cross and find 22 black, 6 chocolate, and 12 yellow. Given your statistical knowledge, interpret your findings for the public in a...

7) In Labrador retrievers, 2 independently assorting genes interact to generate coat color (B, b and E, e). The genotype B_E_ results in black coat; bbE_ results in chocolate coats; B_ee results in yellow coat; and bbee results in yellow coat. If you were a breeder, you might be especially interested in producing black and brown labs, since they might fetch the most money when sold. What proportion of these two phenotypes would you expect from the following crosses? a)...

6. In Cross 1, a yellow eyed, long wing fruit fly from a pure breeding strain is mated to a red eye, short wing fruit fly from a pure breeding strain. All of their offspring (F1) had red eyes and long wings. In Cross 2, one of the F1 offspring is mated to a fly with yellow eyes and short wings, and this cross gave the following F2 population: 194 flies with long wings and red eyes, 796 flies with...

) Bob is deciding how much labour he should supply. He gets utility from consumption of beer (given by C) and from leisure time (given by L), which he spends hanging out with his friend Doug. This utility is given by the following utility function: U(C, L) = ln(C) + θ ln(L) where the value of θ was determined by your student number and ln(C) denotes the natural logarithm of consumption etc. Given this utility function, Bob’s marginal utility from...
