Extra marker chromosomes - what does this mean
Extra marker chromosomes occur when there is an extra chromosome in addition to the 46 chromosomes that make up the normal human genome. this extra chromosome can be derived from any of the chromosomes present in the normal human genome and is usually caused by a random error during the formation of reproductive cells.
What happens during the disease - extra marker chromosomes
Extra marker chromosomes occur when an abnormal number of chromosomes are present in a cell due to an error in cell division. this can happen during meiosis when the normal pairing of homologous chromosomes does not occur, leading to an unequal distribution of the chromosomes. this can also occur during mitosis when a daughter cell fails to separate from the mother cell, leading to an extra set of chromosomes. in either case, the presence of extra marker chromosomes can lead to a variety of health problems, including mental retardation, physical deformities, and developmental delays.
Extra marker chromosomes - Prevention
Extra marker chromosomes can be prevented by avoiding exposure to environmental toxins, practicing safe sex, and avoiding the use of certain medications during pregnancy. additionally, genetic counseling is recommended prior to pregnancy in order to identify any potential risk factors for extra marker chromosomes.
