Only mitosis type of cell division occurs. Both meiosis and mitosis type of cell division occurs.
The progeny and the parent are genetically identical. The progenies will be genetically different from the parents.

. Which mode of reproduction is better and why?
Reproduction :-
Reproduction is the process in which a new offspring is produced by the fusion of gametes or by asexual mode of reproduction.
The 2 types of reproduction namely are :-
- Sexual reproduction
- Asexual reproduction
Sexual reproduction :-
The mode of reproduction with the involvement of the male and the female. In this type of reproduction, fusion of gametes take place to produce a zygote. The development of the zygote can take place internally or externally. The fusion of the male and female gamete is called as fertilization.
Example :- Reproduction in humans
Asexual reproduction :-
The mode of reproduction in which only a single parent is involved for the reproduction. The fusion of gametes don't take place. The offspring is a clone to the parent
Example :- Simple binary fission by amoeba.
Difference :-
Asexual :- Involvement of only one parent
Sexual :- Male and female are involved
Asexual :- No fusion takes place
Sexual :- Fusion of male and female gamete take place
Asexual :- The offspring is a clone to the parent
Sexual :- The progeny produced has traits from both the parents and is a completely different individual.
Which reproduction method is better?
Sexual mode of reproduction is better, as in this type of reproduction, the offspring formed has traits from the mother and father and is not a complete clone, hence every individual will be unique and different than the other.
