The Mendel's laws of inheritance include law of dominance, law of segregation and law of independent assortment.
Some of the key elements of Mendel’s original model were:
Heritable traits are determined by heritable factors, now called genes. Genes come in pairs (that is, are present in two copies in an organism).
Genes come in different versions, now called alleles. When an organism has two different alleles of a gene, one (the dominant allele) will hide the presence of the other (the recessive allele) and determine appearance.
During gamete production, each egg or sperm cell receives just one of the two gene copies present in the organism, and the copy allocated to each gamete is random (law of segregation).
Genes for different traits are inherited independently of one another (law of independent assortment).
