Question

Why are male fruit flies specifically useful for genetic studies given that they are unable to go through recombination? What advantage do they give to geneticists?

Answer 1

As the male fruit flies donor undergo recombination, they are useful to study the classic Mendelian pattern of inheritance of genes. It is useful to study whether the allele is expressing in a dominant or recessive pattern and also whether it is allosomal or autosomal inheritance. Because it doesn't undergo recombination it gives the geneticists the advantage to study the pattern of gene inheritance by eliminating the problem of linkage or any possible mutations.

If you have any query kindly comment before giving thumbs up. Thank you.
