Homework Answers
- The pattern of inheritance is gene interaction.
- When we cross two parents who are heterozygotes for three alleles, we will get 1:1 ratio of brown to white offspring.
- The phenotypic ration after test cross will be 1:1.

/ fn Labrador retrie brown coat color however, the E gene controls expression of the B gene. The B and E genes interact to yield 3 phenotypes: black (B_E), chocolate (bbE) and yellow ee). What is the phenotypic ratio of the pups that might result vers, the B allele confers black coat color and the b allele from a cross between a yellow female (Bbeo and a chocolate male (hb Be) Coat color in Labrador retrievers is an example of...

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...

In Labrador retrievers, coat color is determined by the interaction of two genes (pigment and deposition of pigment). This is called epistasis. Coat color can be black (B) or brown (b) and deposition of pigment into the hair shaft is deposited (E) or not deposited (e). If a retriever has the genotype where they have _ _ ee, then they will have a yellow coat regardless of what color they inherit (e.g., Bbee or bbee gives a Yellow lab). Calculate the phenotypic ratios of a cross between a...

In bunnies, variations are known at two unlinked genes responsible for the coat color. The product of gene Y synthesizes a brown pigment, bunnies homozygous for the recessive loss-of-function allele y of this gene have yellow (golden) coat.The recessive allele b cannot make the black pigment. In a cross of a pure-bred yellow (golden) bunny to a pure-bred brown bunny all offspring are black. Expolain this and predict the frequencies of phenotypes of offspring in F2. ...and the frequencies of...

19. Two different gene loci are responsible for determining mouse coat color. A recessive lethal allele contributing to yellow coat color also exists for one of these two gene loci. The following genotypic and phenotypic information about the mouse coat color alleles is known: (6) Agouti = A-B- • Yellow = AA'B-or A'aB-or A'ab- Lethal (inviable zygote) = A'A- Black = aaB- Albino = -bb a. A cross is made that produces 2 yellow, 1 black, and 3 albino mice....

In rabbits, there are many genes that control coat appearance. The EN gene controls whether the rabbits are solid or spotted. The C gene controls whether rabbits tend to be brown or grey. The alleles of these genes follow a simple dominant/recessive pattern. The following test-cross/mapping-cross was set up: spotted and brown...

BIO340 Recitation 5 Spring 2020 Your professor is having you look at two genes in Drosophila fruit flies to determine experimentally whether they are linked. One trait is eye color and two alleles are present at the gene: se+ is the wild-type allele for red eyes, and se is the mutant, recessive allele for sepia eyes. The second trait is body color and two alleles are present at this gene: e+ is the wild-type allele for grey body, and e...

3. In certain breeds of dogs, black color is dominant and red color is recessive. Solid color is dominant and spotting is recessive. A homozygous black male is crossed with a red-and-white spotted female. What is the probability of them producing a solid black puppy? 4. In horses, black color (B) dominates chestnut color (b). The trotting gait (T) dominates the pacing gait (t). A cross is made...
