Asexual Reproduction I GCSE Biology I Primrose Kitten

How many parents are required for asexual reproduction?

One parent.

How many parents are required for sexual reproduction?

Two parents.

What type of offspring does asexual reproduction produce?

Genetically identical offspring or clones.

Why are offspring of asexual reproduction called clones?

Because there is no mixing of genetic information.

What is a disadvantage of asexual reproduction?

No genetic variation; offspring are susceptible to environmental changes or diseases.

What is a benefit of sexual reproduction?

It introduces genetic variation in offspring.

How do genes contribute to variation in sexual reproduction?

Offspring inherit half their chromosomes from each parent.

What type of cell division is involved in asexual reproduction?

Mitosis.

What type of cell division is involved in sexual reproduction?

Meiosis.

How many daughter cells are produced in asexual reproduction?

Two daughter cells.

How many daughter cells are produced in sexual reproduction?

Four non-identical daughter cells.

Are offspring in asexual reproduction genetically identical to the parent?

Yes, they are clones of the parent.

Are offspring in sexual reproduction genetically identical to the parent?

No, they are genetically different from the parent.

What is the chromosome count in a body cell produced by mitosis?

23 pairs of chromosomes (46 total).

What is the chromosome count in a gamete produced by meiosis?

Half the number of chromosomes of a body cell (haploid).

What is an example of asexual reproduction in plants?

Strawberries producing side shoots (runners) or potatoes producing tubers.

What is asexual reproduction in bacteria known as?

Binary fission

Give an example of an animal that can reproduce asexually.

Starfish or corals

Why do offspring in sexual reproduction have genetic variation?

Because genes from two parents are mixed.
