Covered in a Mendelian Genetics Packet Mendel’s Laws of Inheritance 1. Law of
Segregation Each individual has two alleles for a trait, which segregate during gamete
formation so that each gamete carries only one allele. 2. Law of Independent Assortment
Genes for different traits assort independently of one another during gamete formation,
leading to genetic variation. 3. Dominant and Recessive Traits Dominant alleles mask the
expression of recessive alleles in heterozygous individuals. Key Genetic Terms Included -
