Lincoln Red cattle are entirely red. Hereford cattle have a white face. The white face is due to a dominant allele for which the Hereford breed is homozygous. A farmer has a herd of Lincoln Red cows and Larry, a Lincoln Red bull. Larry was allowed to mate with the cows but died of exhaustion before he had fertilized the whole herd. The farmer borrowed a neighbor's Hereford bull called Herbert, to finish Larry's job. a.) When the calves were born, the farmer had found he could distinguish between Larry's and Herbert's offsprings. How? b.) He kept one of Herbert's male offspring to replace Larry. When this bull was mated to the Lincoln Red cows, what would be the phenotypes of the calves and in what proportions?

Lincoln Red cattle are entirely red. Hereford cattle have a white face. The white face is due to a dominant allele for which Hereford breed is homozygous. A farmer has a herd of Lincoln Red cows and Larry, a Lincoln Red bull. Larry was allowed to mate with cows but died of exhaustion before he had fertilized the whole herd. The farmer borrowed a neighbour’s Hereford bull called Herbert to finish Larry’s job. When the calves were born, the farmer found he could distinguish between Larry’s and Herbert’s offspring. How? He kept one of Herbert’s male offspring to replace Larry. When this bull was mated to the Lincoln Red cows, what would be the phenotypes of the calves and in what proportions?
Two brown bears have cubs in late spring. The mother bear has the phenotype for long front claws. The mother bear has the genotype (Aa), while the father has the same genotype as the mother. A) What percentage of the offspring will have long claws?
Two cats are mated. One of the parent cats is long-haired (recessive allele). The litter which results contains two short-haired and three long-haired kittens. What does the second parent look like, and what is its genotype?
In cats, Manx (M) is a dominant allele that results in cats lacking a tail. The recessive allele (m) gives a cat with a tail. (A) Write out the genotype of a heterozygous cat (B) What is the phenotype of the cat in (A)? (C) The cat in (A) has offspring with a cat that has a tail. What fraction of the offspring of that cat will have tails? In peas, round (R) is dominant to wrinkled. (r )You cross a round pea plant to a wrinkled pea plant and half the offspring are round and half the offspring are wrinkled. What are the genotypes of the parents?
Purple Hair is dominant. Blue hair is recessive. One parent is heterozygous; the other parent has blue hair. A.) What is the probability of them having a blue-haired child?
A liger is the offspring of a female tiger and a male lion. In contrast, the tigon is the offspring of a male tiger and a female lion. These two species do not breed in nature because their habitats are mostly different. Lions live in open grasslands while tigers live in forests. In captivity, it is possible to produce ligers and tigon. Male ligers are sterile but female ligers are fertile and can be bred to either tigers or lions. Is the liger a separate species from lion and tiger? Explain your answer.
In cattle, the gene for hornless (H) is dominant to the gene for horned (h), the gene for black (B) is dominant to that of red (b), and the gene for white face, or Hereford spotting, (S) is dominant to that for solid color (s). A cow (female) that is heterozygous for all traits is inseminated by a bull (male) of the genotype bbhhSs. What is the probability of obtaining a calf that is a black, hornless bull with Hereford spotting?
In cattle, black coat (R), is dominant to red coat (r). Hornless (H), is dominant to horned (h). A certain bull was mated to four cows. Find the genotypes of all cattle mentioned.
făctőrs suc 19) The genotype of a black snake is unknown. Black is a dominant allele, so the snake could be either BB or Bb. You cross this snake with a white snake (bb). Which of the following results of that cross would support the unknown genotype of the black snake being a homozygote? A) All F1 offspring are white B) All F1 offspring are black C) Half of the F1 offspring are white, the other half are black D) Three-quarters of the F1 offspring are black, the other quarter are white В x bb the
Humans have four possible blood types (A, B, AB, and O) and these blood types are controlled by three alleles (IA, IB, i). The IA and IB alleles are codominant, but they are both dominant over the i allele. There was a court case where the identity of a child’s father was in dispute. There were three men who could have possibly fathered the child. Alfie, Beau and Charlie. The mother of the child has type A blood, Alfie has type A blood (one of his parents had Type AB blood and the other had Type A), Beau also has Type A blood (both of his parents were Type AB), and Charlie has Type AB blood. a. List the genotypes for all the possible phenotypes: Phenotype Genotype Blood Type A Blood Type B Blood Type AB Blood Type O b. Who is the father? c. Explain why you think your answer is correct. Use a Punnett square to show your reasoning
Purple Hair is dominant. Blue hair is recessive. One parent is heterozygous; the other parent has blue hair. B.) What is the genotypic ratio of the offspring?
In rabbits, black hair depends on a dominant allele, B, and brown hair on a recessive allele, b. short hair is due to a dominant allele, S, and long hair to a recessive allele, s. If a true-breeding black short-haired male is mated with a brown long-haired female, describe their offspring. What will be the genotypes of the offspring? If two of these f1 rabbits are mated, what phenotypes would you expect among their offspring? In what proportions?
