How many different combinations of chromosomes are possible in the gametes of the fruit fly? Number in fruit flies How many different combinations of chromosomes are possible in the gametes of the house fly? Number in house flies Based on chromosome number, in which species would expect to see more genetic variation among the proge O the fruit fly Genetic variation is equal between these species. the house fly O Hint O Previous Check Answer 0 Next rch ea#@.al

Explanation / Answer

1. Chromosome combination in fruit fly, Drosophila melanogaster is 16. The law for determining the chromosome or allele combination is 2^n. Here 'n' is the number of chromosome or allele pairs. In case of fruifly the number of chromosome pair is 4. Hence, we can get the the chromosome combination 2^4=16.

2. The number of chromosome pair in house fly, Musca domestica is 6. So we can get the chromosome combination=2^n=2^6(where 'n' is the number of chromosome pair) = 64.

3. The genetic variation must be higher in house fly, Musca domestica as it has higher recombination value of it's chromosomes. We know the higher the recombination, the higher the variation.
