In a cross of the parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. All the offspring will be heterozygous and express only the dominant trait.
Law of Segregation
During the formation of gametes, the two alleles are responsible for a trait separate from each other. Alleles for a trait are then "recombined" at fertilization, producing the genotype for the traits of the offspring.
The Law of Independent Assortment
Inheritance at two different loci (a physical site or location within a genome) is independent (most of the time).
