Question

in fruit flies, the traits for a yellow body and white eyes are always inherited together. which conclusion can be drawn from this phenomenon? a. the traits are controlled by one gene. b. both traits are dominant. c. the genes for the traits are adjacent on the same chromosome d. the species has only one allele for each trait.

Explanation:

When traits are always inherited together, it indicates their genes are located close (adjacent) on the same chromosome, a phenomenon called genetic linkage. Option A is incorrect because two distinct traits mean two separate genes. Option B is wrong as inheritance pattern doesn't relate to dominance here. Option D is false since diploid fruit flies have two alleles per trait.

Answer:

C. The genes for the traits are adjacent on the same chromosome
