Mendels laws of segregation only
Each reproductive cell (gamete) is 1N (the haploid chromosome count) which means it has a single allele for a genetic trait at each gene locus...this is based on the assumption that the trait is controlled at a single site. Polygenic traits, those controlled or modified at more than one locus, will have multiple alleles for a trait.
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
single genes wiht multiple alleles
A reproductive cell having a single set of chromosomes, especially a mature sperm or egg. Isn't it supposed to be gamete? yes, it is spelled gamete.
Recessive alleles are expressed if there is no dominant allele (of the same gene) present. This can be for two reasons, because the other allele is also recessive, or because there is no other allele (such as X-linked genes, which males only have one copy of).
chromosome segregationIf the character is governed by a single allele and it is dominant, than its probability to be in the gamete is 75%.
What contains only a single set of chomosomes?

The gamete is supposed to join with another gamete, and combine their chromosomes into a single cell.

A multiple allele system is when there are more than two possible allele pairs for a single locus.

The zona pellucida does.
Natural selection on a single-gene trait can lead to changes in allele frequencies for the alleles of that gene.
