Answer:

Mendel proposed that gene occurred in two copies in every individual. This postulate is similar to homologous chromosomes carrying the two alleles of a gene type. Mendel proposed that one variant was more observant than the other variant. This can be depicted as one allele being dominant over the recessive allele.

Alleles segregate from each other when homologous chromosomes separate during meiosis I. Non-homologous chromosomes line up independently of each other during metaphase I of each meiotic event. This results in independent assortment during anaphase I and completion of meiosis I
