What process returns the diploid number of chromosomes to humans in our life cycle?

The Diploid condition of an organism is restored by Fertilisation.

What process restores the diploid number of an organism in humans?

The process of meiosis produces genetically unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell. Fertilization, the fusion of haploid gametes from two individuals, restores the diploid condition.

How fertilization restores diploid number of chromosomes?

During meiosis the number of chromosomes is reduced from a diploid number (2n) to a haploid number (n). During fertilization, haploid gametes come together to form a diploid zygote and the original number of chromosomes (2n) is restored.

What process restores the chromosome number?

Sexual reproduction includes two distinctive processes: The production of haploid gametes, such as sperm and ova, which involves the specialized nuclear division called meiosis. The fusion of gametes at fertilisation, which results in the restoration of the diploid number of chromosomes.

How is diploid number restored in diploid organisms?

The diploid number is restored when the two haploid cells combine to create a zygote. Basically when the sperm cell enters the egg cell and makes the offspring.

What is the diploid condition?

Diploid describes a cell that contain two copies of each chromosome. Nearly all the cells in the human body carry two homologous, or similar, copies of each chromosome. The only exception is cells in the germ line, which go on to produce gametes, or egg and sperm cells.

What has only one set of unpaired chromosomes?

Haploid. (Of a cell or nucleus) Having a single set of unpaired chromosomes.

What is it called when a cell contains one set of chromosomes?

Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.

What is the function of prophase 1?

Prophase I highlights the exchange of DNA between homologous chromosomes via a process called homologous recombination and the crossover at chiasma(ta) between non-sister chromatids. Thus, this stage is important to increase genetic variation.
