In cattle, the polled (P) or hornless condition is dominant to the horned condition (p). A certain bull was mated to 3 different cows. The first cow was horned (pp) and had a polled calf. The second cow was horned and had a horned calf. The third cow was polled (P) and had a horned

a. What is the genotype of the first cow?

b. What is the genotype of the first calf?

c. What is the genotype of the bull?

Answer #1

P (being hornless) is dominant over p (horned)

So, PP, Pp - hornless

pp - horned

The first and second cow, both were horned (pp) but first had hornless calf (P_) and the second had horned calf (pp), that means the bull is heterozygous (Pp)

The third cow was polled (P_) and had a horned calf (pp)

Genotype of first cow - pp , and it's calf - Pp

Genotype of second cow - pp , and it's calf - pp

Genotype of third cow- Pp , and it's calf - pp

Genotype of the bull - Pp

a. pp

b. Pp

c. Pp

Simmental and Hereford are both white-face breeds of cattle; however, the gene for white face in Simmental is on a different locus from that for Hereford. Both are dominant genes and each breed is homozygous recessive for the other breed’s white-face gene. a) Therefore, if S represents the dominant gene for white-face in Simmental and H the dominant gene for white-face in Hereford, what is the genotype of each breed? Assume the cross between these breeds and subsequent inter se...

Mathephobia is a dreaded (but hypothetical) recessive condition that causes students to go into convulsions whenever they see formulas in biology class. D is the normal allele, d is the mathephobia allele. DD and Dd individuals are normal dd individuals are Mathephobic In a class of 100 biology students, 32 had convulsions during their first population genetics lecture. Assume that students are a representative sample of a population at Hardy-Weinberg equilibrium. a) What is the frequency of the mathephobia (d)...

In tomatoes, red fruit (R) is dominant to yellow fruit (r). Round fruit (B) is dominant to pear-shaped fruit (b). Cross a heterozygous red, round tomato plant with another plant of the same genotype. Now, answer the following questions based on the above cross done by you: 1. What is the genotype of the first parent? 2. What is the genotype of the second parent? 3. What is the probability of getting heterozygous red and round fruit in the offspring?...

3a. In a certain breed of dog long hair is dominant over short hair; the gene involved is autosomal. Another gene, B controls hair colour, which is X-linked, one allele B1 produces gray coloured hair; the other allele B2 produces red coloured hair; and the heterozygous combination B1B2 produces brindle coloured hair (a mix with patches of both gray and red coloured hairs). If a red male homozygous for long hair is mated with a brindle short-haired female, what kind...

Albinism is a recessive disorder that occurs in humans and in guinea pigs too. Assume that an albino guinea pig crossed with a black guinea pig and produces 6 black offspring. When the albino is crossed with a second black guinea pig, 4 black and 3 albino offspring were produced. What genetic explanation would apply to these data? a. The first black guinea pig had genotype AA and the second one aa b. The first black guinea pig had genotype...

1) One parent has yellow flowers, which is the dominant allele Y. The second parent has white flowers, the recessive allele y. If the offspring are all yellow, what is the genotype of each parent? 2) A plant is homozygous for the recessive gene "a" causing the plant to be short. What is the genotype and the phenotype of this plant? (In your answer, be very clear about which is the genotype and which is the phenotype). 3) The allele...

there are 3 dice. the first dice is fair the second dice has probability P(1)=P(2)=P(3)=1/9 P(4)=P(5)=P(6)=2/9 the third has probability p(1)=p(2)=p(3)=p(4)=1/9 p(5)=1/3 p(6)=2/9 if you select one random dice and roll it, and A is the event the fair dice was picked and B the event the result is 6. knowing you rolled a 6, what is the outcome you chose the fair dice?
