Simple Genetics Question About Mendel's laws:

You are studying two genes known to occur on the same chromosome in the Drosophila genome. Which of the following recombinant frequencies would you expect to see if the two genes still follow Mendel’s Law of Independent Assortment? (A) 1% (B) 50% (C) 0% (D) 100% (E) 75%

Answer 1

the maximum recombination frequency between genes is 50%, then the genes are not linked.

according to Mendel`s Law of Independent Assortment alleles of two or more genes assort independently of each other,

but alleles of linked genes do not assort independent of each other, if the genes are linked the recombination frequency is less than 50% and if the genes are unlinked the recombination frequency is 50%

so the recombinant frequency if the two genes still follow Mendel’s Law of Independent Assortment is B) 50%
