Some other organisms have more than two copies of their chromosome types, for example bread wheat which is hexaploid, having six copies of seven different chromosome types for a total of 42 chromosomes. Having two copies of each chromosome ensures that you get the right amount of proteins made by the genes on those chromosomes. This system can also protect you from some diseases. One chromosome in each pair is inherited from the mother and the other from the father. The 22 pairs of chromosomes are called autosomes, and the 23rd pair is called the sex or allosome chromosome. If X chromosome is passed out of XY chromosome, the child will be a female and if a Y chromosome is passed, a male child develops. Control of Cell Division: Chromosomes check successful division of cells during the process of mitosis. chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes. A defining feature of any chromosome is its compactness. For related background details, please refer to our report on 2012 chevy sonic cooling system diagram. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique. The human X chromosome is about three times larger than the human Y chromosome, containing about 900 genes, while the Y chromosome has about 55 genes. The unique structure of chromosomes keeps DNA tightly wound around spool-like proteins, called histones. Chromosome play an important role in growth, repair, reproduction and regeneration. Chromosomes contribute to genetic diversity through processes such as recombination, which increases adaptability and contributes to evolution.
