Several chromosome regions have been defined by convenience in order to talk about gene loci. Most important is the distinction between chromosome region p and chromosome region q. The p region is represented in the shorter arm of the chromosome (p is for petit, French for small) while the q region is in the larger arm (chosen as next letter in alphabet after p). These are virtual regions that e… WebThe sister chromatids are identical to one another and are attached at a compressed region called the centromere.

WebMeiosis I halves the number of chromosomes and is also when crossing over happens. Meiosis II halves the amount of genetic information in each chromosome of each cell. The end result is four daughter cells called haploid cells. Haploid cells only have one set of chromosomes - half the number of chromosomes as the parent cell. WebThis process, also known as meiosis, occurs when a single cell (with 46 chromosomes) divides twice to create two cells (gametes) with half of the original amount of their genetic code (23 chromosomes). These gametes form your body’s sex cells, which are sperm in males and eggs in females.
