In fruit flies, an autosomal mutation in the gene for wing veining results in cross veinless wings. This mutation is recessive.
mezya [45]

Answer:

B. cv+cv w+w

Explanation:

Fruit flies have a special nomenclature to write the genotype of individuals.

  • If the mutation is recessive, you have to write it with lowercase letter(s).
  • If the mutation is dominant, you have to write it with capital letter(s).
  • Wild-type alleles are indicated with a superscript plus (+).

In this problem, both crossveinless (cv) and white (w) mutations are recessive.

<u>For that reason, a heterozygous individual's genotype for both genes will be written as:</u>

<h2>cv⁺ cv  w⁺ w</h2>
