Mendel's Laws

  1. Law of Independent Assortment
    • The inheritance of one character has no effect on the inheritance of another. 
    • Genes inherited independently from each other. 
  2. Law of Segregation
    • There are alternative versions of genes that account for variations in inherited characters. 
    • For each character, an organism inherits two alleles, one from each parent.
    • If the two alleles of an inherited pair differ, then one determines the organism's appearance and is called the dominant allele; the other has no noticeable effect on the organism's appearance and is called the recessive allele. 
    • A sperm or egg carries only one allele for each inherited character because allele pairs separate (segregate) from each other during the production of gametes.
