Match the law with the definition

• Law of Independent Assortment

• States that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic

• Law of Dominance

• States that alleles for the same gene will separate into different gametes

• Law of Segregation

• States that the alleles of two different genes get sorted into gametes separately of one another
