Difference between a Haploid and a Diploid Cell

All the living creatures are formed from cells. A cell is considered the basic functioning unit of every organism. Each of these comes from a cell that existed before the first and these in turn will be followed by their daughter cells, to which they will transmit the genetic material they possess. This genetic material is called the genome. Cells according to the existing chromosomes in their nuclei are divided into haploid cells and diploid cells. Haploid organisms are those that only have one set of chromosomes, that is, half the usual number of chromosomes. In contrast, diploids have both pairs of chromosomes.

Definition We speak of a haploid cell when it is a cell that only contains one set of chromosomes. In contrast, a diploid cell contains two sets of chromosomes.
Effect on mutations Haploid cells are generated in two ways, through mitosis and through meiosis. Either way, this involves exact duplication of the parent cell material, including any possible mutations. This will prevail through the daughter cells as it will continue to be transmitted. In diploid organisms, the effects of deleterious mutations are reduced. Due to the duplication of genomes and multicellularity, the ability to face the effect of mutations is potentiated.
examples Reproductive cells like sperm and egg cells of mammalian creatures are haploid cells When a sperm and an egg (both separate haploid cells) come together and fertilization occurs, the fertilized egg becomes a diploid cell. A little later, this diploid cell becomes a diploid multicellular individual.
