c) Both similarities and variations with parents
Characters that are transmitted from parents to offspring shows both similarity and variation. They show similarity because half of the chromosome comes from the father and half from the mother. They show variation because of genetic recombination, mutation and natural selection.In sexual reproduction, the off springs are not identical to the parents or to one another. This is because the off springs receive some genes from mother and some from father. Because of mixing of genes on re-establishment of number of chromosome in various different combinations, the off springs show both similarities and variations with characters of parents.
