Answer:
c. 1/2
Explanation:
- Polydactyly, the presence of extra digits on hands and feet, possesses an autosomal dominant mode of inheritance.
- To calculate the probability of the third child being polydactyl, we must first figure out the genotypes of the parents.
- Since polydactyly is a dominant trait, the mother must be homozygous recessive as she does not have extra digits.
- Since the first daughter is normal, the father is heterozygous for the allele. If he would have been homozygous dominant, all the children would be affected.

Explanation: I think the way to do it is to just divide the biomass of the primary carnivores by the herbivores since they are the trophic levels right next to each other. Therefore, the efficiency of energy transfer is (2360/25900)*100%=9.112%. Hope that helped!
