Definition

• Sexual reproduction is a type of reproduction that requires two parents.

• It involves the fusion of male and female sex cells (sperm and egg).

• The offspring get half their genes from each parent, so they are genetically different from both.

Key Features

• Involves two parents (male and female).

• Uses gametes (sperm and egg).

• Offspring are genetically unique.

• Common in humans, animals, and many plants.

• Takes more time and energy than asexual reproduction.

Advantages of Sexual Reproduction

• Genetic variation – Offspring are different from parents and each other.

• Better survival – Different traits can help organisms survive changes in the environment.

• Less likely to pass on harmful traits – Because genes mix, bad traits can be hidden or removed.

• Stronger populations – More variety helps species stay healthy over generations.

Disadvantages of Sexual Reproduction

• Slower process – Takes more time to find a mate and grow the baby.

• Fewer offspring at a time – Compared to asexual reproduction, it usually produces fewer babies.

• More energy needed – The body spends more energy growing sex cells, finding a partner, and raising offspring.

• Not always successful – Sometimes fertilization doesn’t happen, or offspring don’t survive.

Favourite part/ note/ summary- There are 2 types of reproduction sexual and asexual reproduction. Sexual reproduction takes more time, takes more energy, and it’s not always successful, the offspring might not survive if the fertilization doesn’t happen the right way, or if the offspring doesn’t survive during the delivery. The advantages are the offspring will be genetically identical, the offspring will have mixed genes form both the parents, there are better survival chances than asexual reproduction, more variety helps species stay healthy over generation.
