Answer 2

1) Sexual reproduction

Definition :- Cellular reproduction in which the no.of chromosomes are reduced to half .

No. of organisms involved :-

Two parents to mate .

Cell division :- Cells divide by Meiosis .

Involvement of sex cells :-

Formation and fusion of male and female gamates takes place .

Time period :-

More time to complete .

Unit of reproduction :-

Gamates is the unit of sexual reproduction .

Evolution :-

Leads to genetic variation in new generations of offspring .

Examples :- Humans , Animals , Plants etc.

2) Asexual Reproduction :-

Defination :- Asexual reproduction in which cell divides into 2 , producing with equal no.of chromosomes in each resulting cell .

No.of organisms involved :-

Only 1 parent to mate .

Cell division :-

Only mitotic division occur.

Involvement of sex cells :-

No gamates are involved .

Time period :-

Less time to complete .

Unit of reproduction :-

Whole parent body or a bud or a fragment or a single somatic cell .

Evolution :-

Little chance of genetic variation , Only mutation in DNA can change the genetic position .
