What is reproduction?

Back

Reproduction is the biological process by which new individual organisms are produced from their parents. It is essential for the continuation of a species.

Front

What are the two main types of reproduction?

Back

The two main types of reproduction are sexual reproduction and asexual reproduction. Sexual reproduction involves the combination of genetic material from two parents, while asexual reproduction involves a single parent producing offspring that are genetically identical to itself.

Define sexual reproduction.

Back

Sexual reproduction is a type of reproduction that involves the fusion of male and female gametes (sperm and egg) to form a zygote, leading to genetic diversity among offspring.

Front

Define asexual reproduction.

Back

Asexual reproduction is a type of reproduction that does not involve the fusion of gametes. Offspring are produced from a single parent and are genetically identical to that parent.

What is a gamete?

Back

A gamete is a reproductive cell that carries half the genetic information of an organism. In animals, the male gamete is called sperm, and the female gamete is called an egg.

Front

What is fertilization?

Back

Fertilization is the process in which a male gamete (sperm) and a female gamete (egg) combine to form a zygote, initiating the development of a new organism.

Front

What is a zygote?

Back

A zygote is the initial cell formed when a sperm fertilizes an egg. It contains a complete set of genetic information from both parents.

Front

What is the role of meiosis in reproduction?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, producing gametes for sexual reproduction. It ensures genetic diversity through recombination and independent assortment.

Front

What is the difference between internal and external fertilization?

Back

Internal fertilization occurs inside the female's body, while external fertilization occurs outside the body, typically in water, where eggs and sperm are released into the environment.

Front

What are the advantages of sexual reproduction?

Back

Advantages of sexual reproduction include increased genetic diversity, which enhances adaptability and survival of a species in changing environments.
