It results in new combinations of genes on each chromosome. ... It is obviously another source of genetic variation in offspring.

Answer: teleconferencing

While instant messaging may work, it can be hard to have a meeting this way.

Templates do not apply to this situation.

This leaves us with the answer of "teleconferencing" as you can have a meeting with people online, even when they are far apart.

The type of mutation that occurred here is an inversion of three nucleotide bases (Option A).

<h3>What is an inversion?</h3>

An inversion is a type of mutation where linear order of nucleotide in the mutated sequence is inverted.

In this case, we have an inversion that involves the following bases (bold highlighted) AATCGC TAC GCACGTCAG and AATCGC CAT GCACGTCAG.

In conclusion, this mutation is an inversion of the genomic sequence (Option A).
