1) Coat color in mice is determined by several independently assorting autosomal genes. Gene A is involved in the distribution of pigment along the hair. A dominant allele (A) produces a hair color called "agouti"--the hair has dark pigment at the base and tip of each hair shaft and yellow pigment in the central portion of the shaft. Homozygous recessive mice (aa) are missing the yellow stripe and thus have solid dark-colored hair. Gene B is involved in the color...
does someone know the answer for these questions? Thank you so
much
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...
1.My wife has black color eyes, the dominant trait. All of her family and relatives have dark eyes too. I have light color eyes (blue), the recessive trait. We are hoping for a blue-eyed baby. What is the probability we will have a baby with blue eyes? What is the probability we will have a baby with dark eyes? 2. In humans, tongue rolling is a dominant trait, those with the recessive condition cannot roll their tongues. Bob can roll...
In humans, brown (B) eye color is dominant to blue (b) eye color and brown (H) hair color is dominant to red (h) hair color. [Assume single-gene traits] Of only the offspring that have brown eyes and brown hair (B_H_, where dash indicates that the individual could be either homozygous or heterozygous for the dominant allele), what proportion are expected to have a genotype that is heterozygous for one of the traits but homozygous for the other trait? A) 1/4...
a female black mackerel stripe tabby with no white spots mated.
with a male orange tabby cat. Among the non-orange kittens from
this mating, half show a tabby pattern and half are solid black
WHAT MUST the two parents agouti genotypes be? Also, what is the
probability of a newborn kitten being an orange male (like the
father)

you adopt a young calico cat from the shelter. before you get a
chance to have her spayed, she becomes pregnant. you are not sure
who fathered the kittens, but when they are born, half are full
color orange including two female kittens
WHAT MUST THE MOM's dilute genotype be if she is full color but
all of her non-orange kittens are grey? and What color is the
father then, assuming he is not all white?

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...
1 point Use the information given below to answer this question. A full colour rabbit (CCa) is mated to a light grey rabbit (CchCa). Calculate the theoretical probability of this cross producing each of the following phenotypes shown below. Record your answer as a full percentage for each phenotype as shown in the following order. Full colour: chinchilla: light grey: Himalayan: albino * Multiple alleles control the coat colour of rabbits. • The dominant allele, produces grey colour. • The...

UNIT GENETICS PROBLEMS #2: TEST CROSSES 1. In peas, green pods are dominant and yellow pods are the recessive trait. You have pea plants with green pods but you are unsure of the parentage of these plants. How would you determine the genotype of your green pod plants 2. Two black mice mate. Six of their offspring are black and two are white. (Black fur is dominant to white.) a· What are the genotypes of the parents....
1) (3 pts) Short hair in rabbits is governed by a dominant allele L and long hair by its recessive allele, l. Black hair results from the action of the dominant genotype B- and brown from the recessive genotype bb. a) What are the gametes possible from a doe (female rabbit) with the genotype Llbb? b) Depict the associated Punnett square or branch diagram for the cross: LlBb x LLBb 2) (6 pts) A dominant sex-linked allele B controls silver-colored...
