Question

which of the following does not function to reshape an organism's genome? choose one: a. gene loss by deletion events b. gene rearrangements c. acquisition of genes from other organisms d. lethal mutations e. spontaneous dna mutations

Answer 1

Lethal mutations do not contribute to reshaping an organism's genome because they result in the organism's death before reproduction, preventing the mutation from being passed on.

Step-by-step explanation:

The option that does not function to reshape an organism's genome is d. lethal mutations. Lethal mutations result in the death of an organism before it can reproduce, which means that the mutation does not get passed on to the next generation and thus, does not contribute to the reshaping of the genome. In contrast, gene loss by deletion events (a), gene rearrangements (b), acquisition of genes from other organisms (c), and spontaneous DNA mutations (e) all can lead to genetic variation that contributes to changes in the genome over time.
