two sets: one for bibliographical information and one for your notes.
Polyploidy Polyploidy is having any number of extra sets of chromosomes. For a diploid organism, having two diploid sets would make it a tetraploid. For a haploid, having two haploid sets would make it diploid. For a tetraploid, having two tetraploid sets would make it octaploid.
Cells with half the genetic information are called haploid cells. Each haploid cell has only one set of chromosomes, whereas diploid cells have two sets. Haploid cells are typically found in reproductive cells such as sperm and egg cells.
Diploid cells have two sets of chromosomes, and are body (somatic) cells.
Somatic cells are diploid, meaning they have two sets of chromosomes.
Stem cells are diploid, meaning they have two sets of chromosomes.
A diploid cell is sometimes described as having two identical sets of chromosomes.This is because for each copy of a chromosome, such as chromosome 7, there is one other copy of the same chromosome.However, such a pair, known as homologous chromosomes, are not truly identical, as they do not have identical base sequences. At any given locus (point on the chromosome) there will be the same type of information, such as a gene, transcription factor, or repeating sequence. But the exact form (allele) will in many cases be different on the two homologous chromosomes.
A diploid cell contains two sets of chromosomes.
