Sexual and Asexual Reproduction

Front

What is sexual reproduction?

Back

A mode of reproduction that involves the fusion of male and female gametes, resulting in offspring that are genetically different from their parents.

Front

What is asexual reproduction?

Back

A mode of reproduction that does not involve the fusion of gametes, resulting in offspring that are genetically identical to the parent.

Front

What is a zygote?

Back

A fertilized egg that results from the fusion of male and female gametes during sexual reproduction.

Front

What is the main advantage of sexual reproduction?

Back

It increases genetic diversity, which can enhance the adaptability of a species to changing environments.

Front

What is a disadvantage of asexual reproduction?

Back

Offspring are genetically identical, which can limit their ability to adapt to environmental changes.

Front

What are genes?

Back

Units of heredity located on chromosomes that determine specific traits in an organism.

Front

Where are genes located?

Back

Genes are located on chromosomes within the cell nucleus.

Front

What is mitosis?

Back

A process of cell division that results in two identical daughter cells, allowing for growth and repair in multicellular organisms.

Front

What would happen if an organism stopped performing mitosis?

Back

The organism would die as it would be unable to replace damaged or dead cells.

Front

What is meiosis?

Back

A type of cell division that produces gametes (sperm and eggs) with half the number of chromosomes, leading to genetic diversity.
