Humans are diploid organisms and almost always have two copies of each gene. This means they have two alleles for every characteristic. Gametes (sex cells) are haploid, which means that they have one allele per gene.
Monohybrid (monogenic) inheritance involves the transmission of one gene from parents to their offspring.
A monohybrid cross tracks the inheritance pattern of the alleles for a single characteristic, controlled by one gene with two possible alleles.
mendel’s simple experiments involved only one characteristic with one pair of contrasting traits
