WebMar 5, 2024 · Other human traits have more complex inheritance patterns. Mendelian inheritance refers to the inheritance of traits controlled by a single gene with two alleles, one of which may be dominant to the other. Not many human traits are controlled by a single gene with two alleles, but they are a good starting point for understanding human heredity. WebApr 11, 2024 · Heterozygous. In diploid species, there are two alleles for each trait of genes in each pair of chromosomes, one coming from the father and one from the mother.
