if we're looking at 2 different alleles, how many alleles is in each gamete?

i think one, is this correct?

Yes, you are correct! Each gamete contains only one allele for a specific gene. When considering two different alleles, an individual inherits one allele from each parent. During gamete formation, the alleles segregate and only one allele is passed on to each gamete. This process is known as segregation. Therefore, each gamete carries only one allele.
