(II) Reproduction A B C D E





(1) Asexual reproduction Is reproduction that involves only one parent and produces offspring

which are genetically identical to their parents

(2) Sexual reproduction Is a type of reproduction which involves the fusion of specialised

male and female sex cells

Is a method of reproduction in which the genetic material and

cytoplasm of a single-celled organism divides equally to form two

new cells

the number of chromosomes
