In Labrador retrievers, black coat color (B) is dominant to brown (b). Suppose that a black Lab is mated with a brown one and the offspring are 4 black puppies and 1 brown. What can you conclude about the genotype of the black parent?
Homework Answers
According to question,
In Labrador retrievers, black coat color (B) is dominant to brown (b), which means brown is recessive
Now, there are ONLY ONE possibilities of crosses when black Lab mate with brown Lab to reproduce atleast one black and one brown puppies. Bb - black, bb - brown
I) Bb X bb = Bb, Bb, bb, bb (BLACK:BROWN = 2:2)
The ratio of getting black and brown puppies from cross (I) is (2:2).
We can
conclude that the genotype of black parent is
(Bb)

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)...

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...

4. In horses, black coat is dominant to brown coat, and trotter to pacer. A black trotter mare has a brown pacer offspring. What is the genotype of the offspring? Genotype of the Mare (female parent)? Genotype of the Stallion (male parent)? Phenotype of stallion? If the stallion could have more than one genotype and phenotype, show how.

Fur color in Labrador Retrievers is a Polygenic trait with Epistasis. There are two genes and two alleles for each gene: Gene 1: Gene 2: B = Black coat (dominant) T = Add pigment to fur (Dominant) b = Brown coat (recessive) t = No pigment (Recessive) (Yellow) Mate two retrievers with these genotypes: Male BbTt x Female bbTt. From the cross above, what is the probability of having a Brown Labrador Retriever puppy?

Fur color in dogs can be black, brown or white. The B gene is responsible for fur color. Dogs that inherit a dominant B will have black fur. Dogs that inherit 2 recessive alleles, bb, will have brown color. There is a second gene that contributes to fur color in dogs: gene I. Individuals who inherit a dominant allele, I, at this location, will always have white color. Individuals who inherit the homozygous recessive condition, ii, will be able to...

the answer I gave was wrong
1 1 - - 1 Hair color is determined in Labrador retrievers by alleles at the Band E loci. A dominant allele B encodes black pigment, whereas a recessive allele b encodes brown pigment. Alleles at a second locus affect the deposition of the pigment in the shaft of the hair; dominant allele E allows dark pigment (black or brown) to be deposited, whereas recessive allele e prevents the deposition of dark pigment, causing...

In rabbits, spotted coat (S) is dominant to solid color (s) and black (B) is dominant to brown (b). A true-breeding black spotted rabbit is mated to a true-breeding brown solid rabbit to Iproduce a heterozygous F1 generation. Two F1 individuals are mated. You see the four expected phenotypes of offspring, but not in the expected 9:3:3:1 (black spotted: black solid: brown spotted: brown solid) ratio. This tells you that o that the genes for fur pattern (spotted vs. non-spotted)...
