When Mendel studied traits the traits what he studied were influenced by only one gene or two alleles. If an organism inherits two of the same alleles for a particular trait, it is homozygous for that trait. Diploid organisms inherit two alleles for each gene; one allele from each parent. An individual can only have a maximum of two of the alleles, one maternal and one paternal, no matter how many alleles exist in the population.
