In a praticular breed of cattle, a black coat is dominant over a red coat. If a cow with a red coat is crossed with a black bull that is heterozygous for coat color, what percentage of their offspring would you expect to be black?

A. 25%
B. 50%
C. 75%
D. 100%
Is the answer C?
Thanks

[I'm adding cliff notes of the questions just in case you have the wrong quiz, then you'd have the wrong answers.]

1. Dog, traits - B
2. Cattle, percent - B
3. Cow, allele - C
4. Mutation - A
5. Humans, Dimples - D
6. Scientist, Flowers - D
7. Child, Inherit - C

I have not been grade for these questions but ill share but all you'll have is my word so don't complain if you get an F

8. Alleles
9. Mitosis
10. Meiosis
11.Incomplete Dominance
12. DNA
13. Reproduce

[Short Answers' Cliff notes]

14. Environment plays a big role, radiation
15. Gametes provide the cells for reproduction which, again, result, in gene diversity
16. Lower genes, lower chance a disease will affect the genes

hope this helped uwu

nope, see other post

It's B. (I'm late ik)

To determine the expected percentage of black offspring, we need to understand the basic principles of Mendelian genetics.

In this particular breed of cattle, black coat color is dominant over red coat color. This means that if an individual has the genotype for both black and red coat colors (heterozygous), only the black phenotype will be expressed.

Now let's consider the parents in this cross. The cow has a red coat, meaning its genotype must be homozygous for red (rr). On the other hand, the bull is heterozygous for coat color (Bb), where "B" represents the allele for black and "b" represents the allele for red.

To determine the possible genotypes and phenotypes of their offspring, we can use a Punnett square.

The possible gametes for the cow with a red coat (rr) are: r.

The possible gametes for the black bull (Bb) are: B and b.

| B | b |
--------------
r | Br | br |
r | Br | br |

As we observe from the Punnett square, 50% of the offspring will have a genotype of Br (black coat) and 50% will have a genotype of br (red coat). Therefore, the correct answer is B. 50% of their offspring would be expected to be black.

I hope this explanation helps!
