Three sub-laws:

  1. Mendel’s Law of Dominance: In a heterozygote, one allele may conceal the presence of another. When one allele affects or masks the expression of another gene.Epistasis
  2. Mendel’s Law of Segregation: During the formation of gametes, the two alleles for a trait segregate from one another, so that each gamete carries only one allele for each gene. The principle that alleles separate during gamete formation.
  3. Mendel’s Law of Independent Assortment: Genes for different traits are inherited independently of each other.
