Question

A population of trees has two alleles of a gene for leaf hairs, alleles D1 and D2. D1 codes for sharp leaf hairs. D2 codes for sticky leaf hairs. homozygous individuals have two copies of D1 or D2. Heterozygous individuals have one copy of each allele, and have both sharp and sticky leaf hairs. Given this information, please indicate which of the following a biologist would infer about the fitness of the genotype A-D1 Homozygotes will have the highest relative fitness B-Heterozygotes will have the highest relative fitness C-D2 homozygotes will have the highest relative fitness D-It is impossible to determine which has the highest fitness

Explanation / Answer

Answer - Option D - It is impossible to determine which has the highest fitness

Because more information about the importance of the leaf hairs and the environment in which it survives has to be known to determine the fitness.
