Did you know?
WebAnaphasic chromosomes do not have chromatids. The two parts of a chromosome or chromatid on either side of primary constriction are called arms. The two arms are equal in isobrachial chromosomes and unequal in heterobrachial chromosomes. The ratio between the two arms of a chromosome is called centromeric ratio. Types of … WebChromosomes in humans can be divided into two types: autosomes (body chromosome (s)) and allosome ( sex chromosome (s)). Certain genetic traits are linked to a person's …
WebThe sister chromatids are identical to one another and are attached at a compressed region called the centromere. This is important for chromosomal separation during cell division. … WebApr 3, 2024 · Metacentric: When the centromere is present in the middle of the chromosomes and forms two equal arms it is called metacentric chromosomes. Sub- metacentric: When the centromere is present slightly away from the middle of the chromosomes is called sub- metacentric chromosomes.
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. 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…

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).
