Question

Some bed bugs had mutations in their genetic code which allowed them to survive the chemical pesticide and they produced chemically resistant offspring. How can this be explained? A) mutations were planned out by the bugs B) bed bugs chose other bugs to partner with who had the mutation C) bed bugs chose other bugs to partner with who had no mutations D) mutations involved the genetic variation of the bugs are random

Answer 1

D. Mutations involved the genetic variation of the bugs are random

Answer 2

Answer:

The correct answer would be D) mutations involved the genetic variation of the bugs are random.

Mutation is defined as a permanent change in the nucleotide sequence of a genome in an organism.

Mutation can be randomly caused by DNA replication errors, exposure to carcinogenic materials or radiations, transposons et cetera. It can sometimes occur spontaneously which are termed as a spontaneous mutation.

Mutation does not always result in loss of function. It may also result in a gain of function such as resistance to any chemical.

Similarly, in bed bugs the mutations which allow their survival against chemical pesticides are random.
