The homologs of a chromosome pair contain the same genetic loci. Therefore, each genetic locus is represented twice in a diploid cell. Variations in inherited characteristics is due to the presence of , which are alternative versions of ... en.wikipedia.org › wiki › MeiosisMeiosis - Wikipedia Meiosis I segregates homologous chromosomes, which are joined as tetrads (2n, 4c), producing two haploid cells (n chromosomes, 23 in humans) which each contain chromatid pairs (1n, 2c). Because the ploidy is reduced from diploid to haploid, meiosis I is referred to as a reductional division . Cell division: mitosis and meiosis | Biological Principles The cell cycle diagram on the left shows that a cell division cycle consists of 4 stages: ... A diploid cell starts with 2N chromosomes and 2X DNA content. After DNA replication, the cells is still genetically diploid (2N chromosome number), but has 4X DNA content because each chromosome has replicated its DNA. Each chromosome now consists of a joined pair of … Genome - Wikipedia Most eukaryotes are diploid, meaning that there are two copies of each chromosome in the nucleus but the 'genome' refers to only one copy of each chromosome. Some eukaryotes have distinctive sex chromosomes such as the X and Y chromosomes of mammals so the technical definition of the genome must include both copies of the sex chromosomes. When referring …
