Question

Now answer the question: What is the probability the wolves will produce a wolf with blue eyes?


25%


0%


100%


50%

Answer 1

I don’t have the parents’ genotypes/pedigree, so I can’t pick one answer for sure. If eye color follows simple Mendelian inheritance with blue (b) recessive and non-blue (B) dominant, the options correspond to these parental crosses:

- 25% → B/b × B/b (both parents carriers)
- 50% → B/b × b/b (one carrier, one blue)
- 100% → b/b × b/b (both blue)
- 0% → B/B × B/B or B/B × B/b (no blue allele from one or both parents)

If you tell me the parents’ phenotypes or genotypes, I’ll give the exact probability. If this is the typical textbook case where both parents are carriers, the answer is 25%.
