What would happen to the possible variation in gametes if the number of chromosome pairs increased from two to three? What if the number increased again from three to four?

The correct answer is: it would create a polyploidy.

Explanation:

Polyploidy consists of an organism or a cell having more than 2 pairs of chromosomes, which in most species (including humans) is abnormal and not compatible with life.

An organism with 3 sets of chromosomes -69 in total- (instead of 46) has a triploidy. In humans, this happens when there's an extra haploid set from one of the parents.

An organism with 4 sets of chromosomes -92 in total- has tetraploidy.

These polyploidies result in miscarriage.

the electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, x-rays, and gamma-rays.

do yall know the answer?
