Question

14/17 what is the significance of the 17% recombination frequency observed by morgan? it represents independent assortment it shows a high rate of mutation it suggests close genetic linkage it indicates genes are on different chromosomes

Explanation:

Morgan's work on fruit flies showed that recombination frequency is related to genetic linkage. Recombination frequency less than 50% indicates genetic linkage. A 17% recombination frequency is much less than 50%, so it suggests close genetic linkage. Independent assortment would lead to a 50% recombination frequency. A high mutation rate is not indicated by recombination frequency. If genes were on different chromosomes, independent assortment (50% recombination) would be expected.

Answer:

It suggests close genetic linkage
