asexual reproduction can be referred to as cloning.
All Genes would be identical
Therefore the young would have same personality, appearance.

Dawkin's description would not tell the completed tale. there are various obvious circumstances the place evolutionary exchange happens in a huge step, the evolution of asexuality from a earlier sexual organism is a style of. this could happen in a pair of techniques. Many asexual "species" are polyploid variations of sexual diploid species (countless instruments of chromosomes vs 2 instruments of chromosomes). with out going into ingredient (which you will discover unquestionably someplace else) a hybridization between 2 species produces offpring that have a unusual form of chromosome instruments (e.g. 3, 5). those offspring can not produce frequent haploid gametes because of the fact their chromosomes do no longer line up peoperly in meiosis. If, on the different hand, a germ line cellular starts off to enhance besides by mitosis (a mutation would be required for this to happen) then you definately've a sparkling asexual "species", reproductively remoted from the two parental species. This has curiously befell in many asexual plant species and a few animal species, such because of the fact the whiptail lizards interior the U. S. southwest. A 2d mechanism has been pronounced wherein a mutation happens that suppresses meiosis in women individuals and helps mitotic divisions in germ line cells. If men are nevertheless produced (demands a non-XY intercourse determining mechanism) the mutation may be unfold by making use of guys. below particular situations the asexuality could be predicted to unfold in the time of the inhabitants freezing the winning genetic version in an array of asexually reproducing clones. this is been pronounced that that's what befell in some waterflea "species" that are completely asexual. because of the fact they have been already able to producing offspring by parthenogenesis (mitosis of diploid eggs) in part of their life cycle the extra step isn't farfetched. those are the two in all likelihood to offer "saltational", or leaping, consequences in evolution from one character state to a distinctive. As an ingredient observe, i've got faith the Dawkin's quote is slightly out of context because of the fact there are various different circumstances the place we are in a position to think of speedy evolutionary exchange and a few have argued that this is the norm in evolution.

Sexual reproduction ensures interchange and recombination of genetic material, so if everything reproduced asexually, there would be very limited genetic diversity and almost no ability to adapt to changing conditions and no ability to respond to disease or predators.
