In many cases, individuals with mild signs and symptoms may be undiagnosed in their lifetime. [1] The chromosome consists of two copies of either the long (q) arm or the short (p) arm because isochromosome formation is equivalent to a simultaneous. Monosomy (the lack of one member of a chromosome pair) and trisomy (a triplet instead of the normal chromosome pair) are typically the result of nondisjunction during meiosis. When this happens, one gamete shows monosomy, and the other shows trisomy of the same chromosome. meiosis E. Treatment with hormones can help manage some of the problems. A mutation occurs and gametes with 48 chromosomes are produced. Chromosomal abnormalities can occur as an accident when the egg or the sperm is formed or during the early developmental stages of the fetus. (1992). Definition. 201 breast carcinoma were reviewed for HER2 gene. Nondisjunction is the failure of two chromosomes to separate during gamete formation, resulting in gametes with either a missing chromosome (monosomy) or an extra one (trisomy).
