There are various types of reproduction. The type of reproduction adopted by an organism depends on:

2. Morphology of the organism

3. Morphology and physiology of the organism

4. The organism’s habitat, physiology and genetic makeup

Select the correct sequence of events.

Offspring formed by sexual reproduction exhibit more variation than those formed by asexual reproduction because:

1.Sexual reproduction is a lengthy process

2.Gametes of parents have qualitatively different genetic composition

3.Genetic material comes from parents of two different species

4.Greater amount of DNA is involved in sexual reproduction.
