No " following, but a condition such as trisomy 21, Downs syndrome, is caused by nondisjuction. The chromosomes fail to separate properly and one child is left with an extra chromosome number 21. The potetial other children that could have been born of this nondijuction event, those with only one chromosome 21, are not viable.

What is nondisjunction and why is it harmful?
Nondisjunction is the failure of a homolog to separate during meiosis causing trisomy (an extra chromosome) or monosomy (a missing chromosome), it can be harmful because it is a mutation that can cause many devastating disease, for example nondisjunction of the 21st chromosome causes down syndrome, another example of nondisjunction being harmful, is nondisjunction of the sex chromosomes, causing Turner's or Klinefelter's syndrome two very devastating diseases.
Many chromosome mutations result when chromosomes fail to separate properly during what?
Meiosis, specifically during anaphase I and anaphase II. This is known as nondisjunction and it causes aneuploidy, such as trisomy 21
The faillure of chromosomes to separate during meiosis is called?
Its called disconjunction. Sometimes it is so bad that they have a miscarriage or the following happens:Trisomy (extra chromosomeso have 47 chromosomes instead of 46)Down's syndrome (andextra number 21 chromosome)Klinefelter's syndrome (males with an extra X chromosome...XXY)
What is the harmful effect of heterotrophs with pseudo pods?
Some types of amoeba can causes diseases.
Is Down syndrome more severe in mitotic nondisjunction or meiotic nondisjunction?
It's more sever in meiotic nondisjunction, since this is the most common way that trisomy 21 (Down syndrome) arises. mitotic nondisjunction is less sever because it means that some cells will be mosaic, meaning they could be normal while some with have the (2n+1) while other cell will be (2n). So, in mitotic nondisjunction it depend how many cells are carrying the extra 21 chromosome. In end of the day they can't be worse than Down syndrome that rose from meiotic nondisjucntion since it has the highest amount of cells carrying trisomy 21.. I hope this helps
