Those species originated from common ancestor show more conserved sequence in genetic material than those of unrelated species.
Offspring formed by sexual reproduction exhibit more variation than those formed by asexual reproduction because (a) Sexual reproduction is a lengthy process (b) Gametes of parents have qualitatively different genetic composition (c) The genetic material comes from parents of two different species (d) Greater amounts of DNA is involved in sexual reproduction
The offspring formed as a result of sexual reproduction exhibits more variations because :
(a) sexual reproduction is lengthy process
(b) genetic material comes from two parents of different species
(c) genetic material comes from two parents of same species
(d) genetic material comes from many parents
