Evolution creates not the best solution but the most available. Building on your answer to the previous question what does this
Greeley [361]

This statement means that evolution has happened by getting the genes of the  right trait expressed at the right time to help adaptability.

Explanation:

Evolution is a result of natural selection which emphasize on the survival of the fittest. But the occurrence of this trait has been possible with genetic variation. It means that if the genes for the particular feature is not present in the genome how would it occur and adapt to the environment. Thus, evolution promotes the most available option for the adaptation and hence for natural selection.

We can conclude that all features are not adaptable some are the results of genetic drift or mutations.

In case of cheetah,  the faster running genes would have been there they got expressed over the period of time for better adaptability.

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>
