What are the products of nondisjunction?

Answer 1

Monosomy refers to a condition in which there is one chromosome is missing. Turners Syndrome the individual contain only 1 X chromosome.
A trisomy has one extra chromosome and is abbreviated 2N + 1. Trisomy 21 ( Downs syndrome)is an example of a trisomy in which cells have an extra chromosome 21.
Monosomies and trisomies usually result from nondisjunction during meiosis but can also occur in mitosis. They are more common in meiosis 1 than meiosis
Other examples of nondisjunction:
Trisomy 18 (Edward Syndrome)
Trisomy 13 (Patau Syndrome)
Polyploidy is a condition in which there is more than 2 sets of chromosomes.
Triploids (3N), tetraploids (4N), pentaploids (5N) etc. are polyploids.
Human polyploids have defects in nearly all organs.
Most die as embryos or fetuses. Occasionally an infant survives for a few days.
Abnormalities of the Sex Chromosomes
XXX - Triple-X Syndrome (also XXXX and XXXXX)
Triple-X individuals are tall and thin and have menstrual irregularities. Their IQ is in the normal range but it is slightly reduced. The incidence of Triple-X Syndrome is 1 in 1,500 female births. Additional X chromosomes are associated with an increased mental handicap.
XXY - Klinefelter Syndrome (also XXXY)
XYY - Jacob Syndrome XYY males are tall, have acne, speech, and reading problems.

Answer 2

Nondisjunction is the failure of paired chromosomes or sister chromatids to separate and go to different cells during meiosis...so the products are the left over sister chromatids

Answer 3

Nondisjunction results in gametes with one more than the usual number of chromosomes and other gametes with one fewer than the usual number of chromosomes.
