Why must a gamete carry one allele from each gene

I don't know how to word it, but basically each gamete contains one allele of each gene, and each gene pair must separate into different gamete cells so yea.

Explanation:

"Each parent passes an allele at random to their offspring resulting in a diploid organism. The allele that contains the dominant trait determines the phenotype of the offspring. In essence, the law states that copies of genes separate or segregate so that each gamete receives only one allele."

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
