Sexual Reproduction
Sexual reproduction is the formation of a new individual by the fusion of male and female gametes from two parents.
Practice This ConceptMain explanation
Teacher explanation
In sexual reproduction, two gametes combine to form a zygote. The offspring receive characteristics from both parents, so they show variation. In flowering plants and humans, this process is important for continuity of life and genetic diversity.
Example
In humans, the sperm fuses with the ovum to form a zygote.
Simple analogy
Two gametes join, one new start.
Common confusion
Students sometimes say sexual reproduction always means direct birth of a baby or seed. The key idea is fusion of gametes, not the final form alone.
Exam tip
When you see two parents, gametes, fertilisation, or zygote, connect them to sexual reproduction.
