Based on genome sequencing, what is the level of variation in the genomes of fruit flies in natural populations?Multiple choice question.Fruit fly genomes have very low levels of variation, except for a few very important genes, such as those involved in development.Fruit fly genomes have very low levels of variation.Fruit fly genomes have extensive variation

Similar to humans, fruit flies Blank______.Multiple choice question.exhibit uniform levels of variation across their entire genomeexhibits much higher levels of variation in certain parts of their genomeexhibit very low levels of variation in their genome

Genetic variation is the difference in DNA sequences between individuals within a population. Variation occurs in germ cells that are passed on from parent to offspring. Which of the following is true about mutations?Select one:a.Certain mutations allow organisms to better survive in the environment and the traits are passed on.b.Mutations in the organism's somatic cells are passed onto offspring causing variations in the population.c.Certain mutations are beneficial and lead to variation because the organism does not survive.d.Mutations are always harmful to a population when passed on.

Experiments with fruit flies have shown that significant evolutionary change can be observed within Blank______.Multiple choice question.1-2 generations35-40 generationsno fewer than 100 generations

Which of the following best describes the genetic variation of a population?Multiple choice question.Genetic variation refers to the fact that different individuals of a population have different alleles of genes.Genetic variation refers to the fact that an individual organism's alleles for a gene can vary during its development.Genetic variation refers to the fact that in most populations there are two sets of each gene present in each individual.

In the laboratory setting, selection for a trait in fruit flies Blank______.Multiple choice question.has had mixed responses (as predicted for some traits but not for others)has consistently lead to a strong, predictable evolutionary responsehas never achieved a consistent, predictable evolutionary response
