A black mare is crossed to a chestnut stallion and a bay colored son and a bay colored daughter are produced. These two offspring are mated to each other several times and the resulting coat colors in their offspring is produced: black, bay, chestnut, roan and liver A liver grandson (F2) mated to its black grandmother (P) results in bay horses A roan granddaughter (F2) mated to its chestnut grandfather (P) results in a chestnut horse and a roan horse In the following blanks - fill in the correct genotype for these F2 horses using the letters B/b and S/s Use a dash "-" if you do not know the second allele - e.g. A- black - roan - chestnut - liver - The genotype BbSS would produce a horse

. A black mare was crossed to a chestnut stallion andproduced a bay son and a bay daughter. The two offspring were mated to each other several times, andthey produced offspring of four different coat colors:black, bay, chestnut, and liver. Crossing a liver grandson back to the black mare gave a black foal,and crossing a liver granddaughter back to the chestnut stallion gave a chestnut foal. Explain how coatcolor is being inherited in these horses.
Your significant other is a big fan of hamsters due to their appearance and you eventually gift them two hamsters that are curly (C) brown (B) that you got from the local pet store. Weeks later your significant called you that the hamsters have an offspring that is curly white (b) and straight (c) brown. You are astonished and start to think what the probability was to have a curly white hamster?
For Dalmatian dogs, the spotted condition is dominant over non-spotted. (a) Using a Punnett square, show the results of a cross between two heterozygous parents. ( please draw the punnet square and write the parent and G and f1: thanks) (b) A spotted female Dalmatian dog mates with an unknown father. From the appearance of the pups, the owner concludes that the male was a Dalmatian. The owner notes that the female had six pups, three spotted and three non-spotted. What are the genotype and phenotype of the unknown male?
Assume that in horses, black coat colour is dominant (B) to chestnut colour (b). The troting gait is due to a dominat allele (T), and the pacing gait is a recessive allele (t) a) If two Black trotting horses are mated and have for offsprings, all of which are black and pacing, what does that reveal about the probable genotype of the parent horses? b)A stud is black and trotting. He is mated with a mayor who is also black and trotting. Their colt is black and pacing. The same stud is mated to a second mare who is Chestnut and pacing. Their colt is Chestnut and trotting. What is the probable genotype(s) of the stud, mare 1, colt 1, and colt 2
Three coat-color patterns that occur in some breeds of horses aretermed cremello (beige), chestnut (brown), and palomino (goldenwith light mane and tail). If two palomino horses are mated, theyproduce about 1/4 cremello, 1/4 chestnut, and 1/2 palomino offspring. In contrast, cremello horses and chestnut horses breed true.(In other words, two cremello horses will produce only cremellooffspring, and two chestnut horses will produce only chestnut offspring.) Explain this pattern of inheritance.
In horses, black coat color (B) is dominant over roan coat color (b), and a trotter (T) is dominant over a pacer (t). A black trotter mare was bred with a stallion to produce a roan pacer colt. Determine the genotypes of the colt and mare and all the possible genotypes for the stallion. What is the highest probability for the stallion’s genotype?
Palomino horses have a golden yellow coat, chestnut horses have a brown coat and cremello horses have an almost white coat. A series of crosses between the 3 different types of horses produced the following offspring: Offspring 13 Palomino, 6 chestnut, 5 cremello Cross Palomino x palomino Chestnut x chestnut 16 chestnut Cremello x cremello 13 cremello Palomino x chestnut 8 palomino, 9 chestnut 11 palomino, 11 cremello 23 palomino Palomino x cremello Chestnut x cremello B) Assign symbols for the alleles that determine these phenotypes, and list the GENOTYPES of all the parents and offspring given in the table above.
If a pure breeding(homozygous) black(dominant), longhaired (recessive) cat is made of pure breeding Siamese, shorthaired cat, and one of their male offspring has made it to one of their female offspring, what is the chance of producing a Siamese colored shorthair kitten?
A female fruit fly with vermilion eyes and normal wings is crossed with a male with normal red eyes and cut wings. The F₁ progeny consist of females with red eyes and normal wings, and males with vermilion eyes and normal wings. When the F₁ progeny are interbred, the F2 consists of two types of females-vermilion eyes, normal wings (1/2) and red eyes, normal wings (1/2), and two types of males- vermilion eyes, normal wings (1/2) and red eyes, cut wings (1/2). Are the genes for eye colour and wing type X-linked or autosomal? Both genes are X-linked. The eye-colour gene is X-linked and the wing-type gene is autosomal. The eye-colour gene is autosomal and the wing-type gene is X-linked. Both genes are autosomal. More than one of the choices is consistent with the data.
A pea plant showing two dominant phenotypes, tall plant (D) and purple flower color (W) is test-crossed with a plant showing both recessive phenotypes for dwarf plant (dd) and white color flower (ww). The results of the F1 offspring showed tall purple flower plants; tall white flower plants; dwarf purple flower plants; and dwarf white flower plants in approximately a 1:1:1:1 ratio. Based on these observations, what should be the genotype of the tested plant? DdWw DdWW ddWw DDWw DDWW
A walnut comb rooster is mated to three hens. Hen A, which has a walnut comb, has offspring in the ratio of 3 walnut to 1 rose. Hen B, which has a pea comb, has offspring in the ratio of 3 walnut to 3 pea to 1 rose to 1 single. Hen C, which has a walnut comb, has only walnut comb offspring. What are the genotypes of the rooster and the three hens?
Palomino horses have a golden coat color, with a white mane and tail. Palominos do not breed true. Instead, there is a 50% chance that a foal with two Palomino parents will be a Palomino. What is the explanation?
