This law explains that the pair of alleles segregate from each other during cell division ( gamete formation ) so that only allele will be in each gamete . In a cross , both the alleles are expressed in the generation any . Thus , the law of segregation is based on the fact that each gamete contains only allele . This law is based on basic concepts . 3 not color influence shape independent another sorted alleles independently assortment Mendel's law of states that the of two ( or more ) different genes get into gametes of one another . In other words , the allele a gamete receives for one gene does the allele received for gene . Example : Pea and pea gene s
