Chromosome 13
During cell division, the chromosome number remains constant. In mitosis, each daughter cell receives an identical set of chromosomes to the parent cell. In meiosis, the chromosome number is halved to produce gametes with half the number of chromosomes as the parent cell.
Poly X females have an extra X chromosome, resulting from nondisjunction during meiosis in one of the parents. This leads to the presence of three X chromosomes (XXX) instead of the typical two. This extra chromosome can result in physical and cognitive differences in affected individuals.

The chromosome carried only by the sperm is called the Y chromosome, which determines the male gender when combined with the X chromosome from the egg during fertilization.
A chromosome with a sub-terminal centromere has its centromere located towards one end of the chromosome rather than in the middle. This can affect the behavior of the chromosome during cell division and can impact genetic inheritance and variability.
No
If multivalvular disease is suspected or involved, different valves may be evaluated during surgery on one of the affected valves.
During the 1840s, potato blight affected potatoes in Ireland, causing a famine.
He was dead in 1920.
The Wilsons in "The Grapes of Wrath" came from Sallisaw, Oklahoma. They were a migrant family seeking work and a better life in California during the Great Depression.
During cell division, the chromosome number remains constant. In mitosis, each daughter cell receives an identical set of chromosomes to the parent cell. In meiosis, the chromosome number is halved to produce gametes with half the number of chromosomes as the parent cell.
affected people typically have no history of the disorder in their family. Most cases of Prader Willi syndrome are not inherited, particularly those caused by a deletion in the paternal chromosome 15. Tehse genetic changes occur as random events during the formation of reproductive cells or in early fetal development. There are no targets for this horrible disease.
The family the Joads travel with is the Wilson family. They meet the Wilsons during their journey to California and develop a close friendship as they face challenges together on the road.
The chromosome number is halved during cell division in meiosis, not mitosis.
The chromosome number is halved during the process of meiosis in the cell cycle.
Poly X females have an extra X chromosome, resulting from nondisjunction during meiosis in one of the parents. This leads to the presence of three X chromosomes (XXX) instead of the typical two. This extra chromosome can result in physical and cognitive differences in affected individuals.
Disease affected the world greatly during WW2. Tuberculosis, rheumatic fever, hepatitis, and topical diseases were the main cause of disability and time lost from duty.
