sexual and asexual reproduction

asexual reproduction

A type of reproduction where offspring are produced from a single parent without the involvement of gametes.

sexual reproduction

A type of reproduction involving the fusion of male and female gametes, resulting in offspring with genetic variation.

What is a key characteristic of offspring in asexual reproduction?

Offspring are genetically identical to the parent (clones).

Name one organism that reproduces asexually.

Bacteria (binary fission), fungi (spores), or plants like strawberries (runners).

What are gametes in animals?

sperm and egg cells

What is the main advantage of sexual reproduction?

It introduces genetic variation, which can help populations adapt to changing environments.

What is the main advantage of asexual reproduction?

It is fast and does not require a mate, which is useful in stable environments.

What type of cell division is involved in asexual reproduction?

mitosis

What type of cell division is involved in the production of gametes for sexual reproduction?

meosis

What is a disadvantage of asexual reproduction?

Lack of genetic variation can make populations vulnerable to diseases or environmental changes.

What is a disadvantage of sexual reproduction?

It is slower and requires more energy to find a mate and produce offspring.

Give an example of an organism that reproduces both sexually and asexually.

Fungi, such as mushrooms, or plants like strawberries.

What is the process of gamete fusion called?

fertilisation

What is the result of fertilization in sexual reproduction?

: A zygote, which develops into an organism.

Why is genetic variation important in populations?

It increases the chances of survival and adaptation in changing environments.

What are identical twins, and how do they relate to asexual reproduction?

Identical twins result from the splitting of a single fertilized egg and are genetically identical, resembling the outcome of asexual reproduction.
