Answer :
To solve the question regarding the alleles of the offspring when a red cow is crossed with a white cow:
1. Identify the Genotypes of the Parents:
- A red cow that is homozygous dominant has a genotype of RR. This means it has two dominant alleles for the red color.
- A white cow that is homozygous dominant has a genotype of WW. This means it has two dominant alleles for the white color.
2. Determine the Possible Genotype of the Offspring:
- When crossing these two cows, the offspring will inherit one allele from each parent.
- Therefore, the offspring will receive one R allele from the red cow and one W allele from the white cow.
3. Resulting Genotype:
- The resulting genotype of the offspring will be RW, which combines one allele from each parent.
4. Answer:
- The offspring will have the alleles RW.
Thus, the correct answer is RW.
