A population of lizards carry a gene for scale color in which the dominant allele produces green scales while the recessive allele codes for brown scales. In the first generation, you determine that 75% of the population is green and 25% of the population is brown. In the second generation, you determine that 50% of the population is green and 50% of the population is brown. Finally, in the third generation, you determine that 25% of the population is green and 75% of the population is brown. Which of the following correctly explains this change in the genotype frequencies?(1 point)

The lizards mate randomly with each other.

The brown color is an adaptation that is being selected by the environment.

The lizards remain isolated from other lizards, only mating with lizards in their own population.

The DNA of these lizards carries no mutations from one generation to the next.

Respuesta :

Answer:

1) There are no mutations in the DNA of the population.

2) The brown color is an adaptation that is being selected by the environment.

3) The number of individuals displaying each phenotype in both the current generation and the offspring.

4)The recessive phenotype in this population may serve as an adaptation in this environment.

5) A population of flies that maintains a population size of at least 1 million individuals.

Explanation:

just took the test (connexus student)

Correct answers are :

  • No mutations in the DNA.
  • The brown color is an adaptation.
  • individuals displaying current generation, offspring.
  • Rcessive phenotype adaptation.
  • Flies population has a size of at least 1 mn.

What is a genotype?

A genotype is a set of genetic material that characterize an organism and is also used or refer to the allies or the variant of that individual that carries genetic material.

The population of lizards has a gene for scale color that is a domain allele. The brown color is due to the adaptation of the species.
