Mitosis VS Meiosis

Front

What is mitosis?

Back

Mitosis is a type of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell. It is used for growth, repair, and asexual reproduction.

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse daughter cells. It is essential for sexual reproduction.

Front

How many chromosomes do humans have?

Back

Humans have 46 chromosomes, arranged in 23 pairs.

Front

What is the main purpose of mitosis?

Back

The main purpose of mitosis is to produce identical cells for growth, repair, and asexual reproduction.

Front

What is the main purpose of meiosis?

Back

The main purpose of meiosis is to produce gametes (sperm and eggs) for sexual reproduction, ensuring genetic diversity.

Front

What are alleles?

Back

Alleles are alternative forms of a gene that determine specific traits. For example, a gene for flower color may have a red allele and a white allele.

Front

What is reduction division?

Back

Reduction division refers to the process in meiosis where the chromosome number is halved, resulting in gametes with half the number of chromosomes.

Front

What percentage of chromosomes does a sperm cell contribute to the offspring?

Back

A sperm cell contributes 50% of the chromosomes to the offspring.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA sequences among individuals, which can lead to different traits. It is increased through meiosis.

Front

What is the difference between asexual and sexual reproduction?

Back

Asexual reproduction involves one parent and produces identical offspring, while sexual reproduction involves two parents and produces genetically diverse offspring.
