Following mitosis, a cell is said to contain 1 sister chromatid (separated from sister chromatid pair) . How is this cell still considered diploid? How is this cell considered to have 2n chromosomes? How is this cell said to have 2 copies of each gene, and therefore 2 alleles? mitosis

Mitosis

The truth that a cell is taken into account diploid after mitosis might be defined by the character of the sister chromatid. Throughout mitosis, the chromosomes separate and kind two an identical copies of the unique chromosome, generally known as sister chromatids. These sister chromatids nonetheless include the identical DNA as the unique chromosome, so the cell continues to be thought of diploid as a result of it accommodates two units of chromosomes. Due to this fact, the cell continues to be thought of to have 2n chromosomes, the place n is the haploid variety of the species. Moreover, the sister chromatids are precise copies of the unique chromosome, so this cell nonetheless has two copies of every gene, and subsequently two alleles. For the reason that sister chromatids have the identical sequence of nucleotides, because of this the cell continues to be thought of diploid, with two copies of every gene, and subsequently two alleles. That is essential for genetic variation, because it implies that the cell is able to expressing completely different traits as a result of two completely different alleles (Lai et al., 2016). Cont…
