Sexual Reproduction & Development

Front

What is sexual reproduction?

Back

A biological process where two organisms contribute genetic material to produce offspring, resulting in genetic diversity.

Front

What is meiosis?

Back

A type of cell division that reduces the chromosome number by half, producing four gametes, each with half the number of chromosomes of the original cell.

Front

What is fertilization?

Back

The process where a sperm cell unites with an egg cell to form a zygote, initiating the development of a new organism.

Front

What is the significance of genetic variation in sexual reproduction?

Back

It increases the chances of survival and adaptation of a species by producing offspring with diverse traits.

Front

How many chromosomes do humans inherit from each parent?

Back

Humans inherit 23 chromosomes from each parent, totaling 46 chromosomes.

Front

What is a zygote?

Back

A fertilized egg that results from the union of a sperm and an egg, which will develop into an embryo.

Front

What is asexual reproduction?

Back

A mode of reproduction where an organism can reproduce without the involvement of gametes, resulting in offspring that are genetically identical to the parent.

Front

What is differentiation in biological terms?

Back

The process by which cells become specialized in structure and function during development.

Front

What is the role of chromosomes in inheritance?

Back

Chromosomes carry genes, which are the units of heredity that determine traits in an organism.

Front

What is the difference between sexual and asexual reproduction?

Back

Sexual reproduction involves two parents and results in genetic variation, while asexual reproduction involves one parent and produces genetically identical offspring.
