Your Answer: Mendel concluded that genes are inherited from each parent as separate, paired units by observing how parental genes separated and if they showed up as dominant or recessive qualities in the children. So that each cell only contains one of a pair of parental genes, parental genes are arbitrarily distributed among the daughter cells. Therefore, when cells combine to form offspring during fertilization, they receive one genetic allele from each parent. To ensure that the inheritance of one feature is independent of the inheritance of another, distinct traits' genes are arranged in separate groups.
