Diploidnej

Diploidnej refers to a state in which a cell or organism contains two complete sets of chromosomes, one inherited from each parent. This is the most common chromosomal state for many eukaryotic organisms, including humans. In diploid cells, chromosomes are present in homologous pairs. One chromosome of each pair comes from the mother, and the other comes from the father. These homologous chromosomes carry genes that control the same traits, although the specific versions of those genes (alleles) may differ. For example, a diploid human has 23 pairs of chromosomes, totaling 46 chromosomes. Gametes, such as sperm and egg cells, are typically haploid, meaning they contain only one set of chromosomes. During sexual reproduction, the fusion of a haploid sperm and a haploid egg restores the diploid state in the resulting zygote. This diploidy is crucial for genetic diversity, as it allows for the combination of genetic material from two individuals. Many biological processes, including growth, development, and tissue repair, rely on cells maintaining their diploid state. Deviations from diploidy, known as aneuploidy, can lead to various genetic disorders.
