Question

what does having higher fitness mean in an evolutionary sense?
○ an individual with better alleles will be more likely to win competitions for mates.
○ a particular genotype produces stronger or healthier individuals than another genotype does.
○ individuals with genotypes favorable for current conditions are more likely to survive and reproduce.
○ species with more allele variations have a higher probability of surviving changing environments.

Explanation:

Evolutionary fitness refers to an organism's ability to survive and pass its genes to the next generation. The correct option directly aligns with this definition, as it links favorable genotypes (for current environmental conditions) to increased survival and reproduction—key components of evolutionary fitness. Other options are incorrect: "better alleles" and "mate competition" are narrow (fitness isn’t just about mating), "stronger/healthier" is not the evolutionary definition, and "allele variations in species" refers to genetic diversity, not individual fitness.

Answer:

Individuals with genotypes favorable for current conditions are more likely to survive and reproduce.
