Question

9) Genetic variation is the source for evolution. Without a variety of phenotypes, there would be no differential survival upon
which natural selection can act. Which of these are sources of the genetic variation within a population? Select ALL that apply.
A) Errors caused by DNA polymerase during replication.
B) The failure of DNA to separate during DNA replication
C) Changes to the ribosomal structure during translation
Eliminate
D) Induced changes to the genome from environmental factors
E) Fertilization of two haploid gametes during sexual reproduction.

Answer 1

The genetic variation occurs due to induced changes to the genome from environmental factors, fertilization of two haploid gametes during gamete fusion. The correct options are D and E.

What is genetic variation?

The presence of differences in gene sequences between individual organisms of a species is referred to as genetic variation. It allows for natural selection, which is one of the primary forces driving life's evolution.

The genetic variation occurs due to induced changes to the genome from environmental factors, fertilization of two haploid gametes during gamete fusion.

Thus, the correct options are D and E.
