Question

A roan cow is crossed with a red cow. What percent of the offspring will be roan?

Answer 1

Answer:

Red cows have a dominant red allele and white cows have a dominant white allele. When a red cow mates with a white bull, they can have offspring that have the color that is called Roan which is a red and white spotted appearance. This is an example of co-dominance

Answer 2

If a roan cow is crossed with a red cow, the percentage of roan cow in the offspring will be 50%.

CO-DOMINANCE:

• A roan cow phenotype is a product of co-dominance between red (R) and white (W) alleles. This means that a roan cow will have a RW genotype.

• If a roan cow is crossed with a red cow i.e. RW × RR, the gametes produced by each cow is as follows:

1. RW - R and W
2. RR - R and R

• Using a punnet square, the following offsprings of cow will be produced: 2RR, and 2RW.

• This means that the percentage of roan cows in the offspring will be 50% i.e. ½ × 100 = 50%.

Therefore, If a roan cow is crossed with a red cow, the percentage of roan cow in the offspring will be 50%.
