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 a yellow lab and a brown lab, what phenotypes and ratio which you expect among the puppies. (The answer is 9 black, 3 brown and 4 yellow. I just don't know how to get these answers). Thanks!

Labrador retrievers are black, brown, or yellow. In a cross of a black female with a brown male, results can be all black puppies, 1/2 black to 1/2 brown puppies, or 3/4 black to 1/4 yellow puppies. What is/are the genotype(s) that results in the black phenotype, brown phenotype, and yellow phenotype?

Labrador retriever dogs have three coat colors: black, brown and yellow. The color of the pigment deposited in the hairs is determined by a gene with two alleles (B or b). The B allele codes for black pigment and is dominant to the b allele which codes for brown. Another gene with two alleles (E or e) determines if the pigment created will be deposited into the hairs. If both copies (ee) are recessive, no pigment will be deposited (regardless...

#1. You have two pure-bred dog strains of Labrador retriever: Yellow (BBee) and Brown (bbEE). You friend wants to have a pure-bred puppy with black coat color. Let’s assume this set of coat color variations follows recessive epistasis with the allele ‘ee’ masking B or b. A) provide breeding schemes B) after breeding experiments, provide a scheme of identifying the pure-bred one with black color. Also, what is the frequency of the pure-bred one among the black puppies. #2. In...

A black, short-haired cat has a litter of kittens with an orange, long-haired cat. The litter is entirely long-haired with mottled black and orange fur. What must be the inheritance pattern for each trait? a. Short hair is dominant to long hair, and color shows incomplete dominance. b. Short hair is dominant to long hair, and color shows codominance. c. Long hair is dominant to short hair, and color shows incomplete dominance. d. Long hair is dominant to short hair,...

Labrador retriever coat colour exhibits a pattern of inheritance called epistasis. ‘B’ defines fur colour and ‘E’ defines deposition of pigment. P generation is a cross between parent1, Bbee, and parent2, bbEe. What are the genotype and phenotype ratios of the offspring?

1- Labrador retrievers can be one of three colours: black, chocolate brown, and yellow. The proportion of puppies born with each coat colour can be predicted by the genotypes of the parents. One set of parents produced 50 puppies (in six litters), and we've recorded the observed numbers of puppies with each coat color. We only know the coat colours of the parents and not their exact genotype at the locus determining coat colour, and we want to test our...

A brown Golder Retriever with short hair (dog X) is of an unknown genotype. To identify the genotype, a test cross was carried out between this dog and another Golder Retriever with light-color and long hair, both of which are known to be recessive traits. 50% of the F1 offspring from this cross are brown with short hair and the other 50% are light-coated with short hair. A) What is the genotype of dog X? Explain your answer (you can...

1) A breeder performed a testcross to find out if his male dog was a purebred black. He got one brown puppy and seven black puppies, did he have the purebred? (explain) What was the genotype of the female dog he used in test cross (BB), (Bb), or (bb)? (explain) 2) Given the description of an inherited disorder (including a pedigree) which of the following shows the probable mechanism of inheritance of this color? (Autosomal recessive, autosomal dominant X-linked recessive,...

Mendelian genetics predict that in Labrador retrievers (a type of dog), 25% should have brown coat color if both parents are heterozygous (the rest are black). You mate two parents and get a litter of 8 puppies. Calculate the following: a) The probability of 6 black puppies. b) The probability of 3 brown puppies. c) The probability that 50% of the puppies will be brown. (Comment: You do not need to know anything about genetics to solve this problem. If...
