Genotypes are the genetic makeup of an organism, typically represented by a combination of letters or symbols that represent specific alleles for a particular gene. The matches of genotypes refer to the specific combinations of alleles that are present in an individual's genetic makeup.
For example, in a simple genetic trait where there are two possible alleles (A and a), the possible genotypes and their matches would be:
In a more complex genetic trait with multiple alleles, there can be a variety of different genotypes and matches depending on the specific alleles involved. The matches of genotypes are important in determining an individual's phenotype, or physical characteristics, as well as their potential for passing on certain traits to future generations.
