Mendel’s Laws

Mendel's Laws

Law of Segregation

• For each trait and organism has two hereditary factors now called genes
  
• Alternate forms of the gene are called alleles
  
• The two alleles separate during meiosis and only one is passed on to the gamete
  
• The two gametes unite during fertilization to produce an offspring with two genes
  
• If the two alleles differ, the phenotype will reflect the dominant allele
  
• Not all genes have dominant and recessive alleles
  

 

Law of Independent Assortment

The inheritance of one gene does not normally affect the inheritance of another gene
