A wild-type fruit fly (heterozygous for gray body color and normal wings) is mated with a black fly with vestigial wings. The offspring have the following phenotypic distribution: wild type, 778; black-vestigial, 785; black-normal, 158; gray-vestigial, 162. What is the recombination frequency between these genes for body color and wing size

Respuesta :

Recombination between these genes for body color and wing size occurs at a frequency of 17.

What is the frequency of recombination?

  • The frequency of a single chromosomal crossover occurring between two genes during meiosis is known as the recombination frequency ().
  • The measure used to describe recombination frequencies of 1% is the centimorgan (cM).

What does it signify when recombination occurs frequently?

Therefore, we can conclude that two genes with different recombination frequencies are probably farther apart than they are when compared to two genes with similar recombination frequencies.

Can the frequency of recombination be 100%?

Because a random array of genes produces 50% recombination (non-linked genes produce 1:1 parental to non-parental), the frequency of recombination between two genes cannot be more than 50%.
