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

What type of error usually results in zygotes that either do not develop to term or have severe abnormalities?
Chromosome nondisjunction.
Triple X syndrome occurs because of whAT?
Triple X syndrome, also known as trisomy X, occurs when a female has an extra copy of the X chromosome, resulting in a total of three X chromosomes instead of the typical two. This genetic anomaly happens randomly and does not usually cause severe symptoms, but some individuals may experience mild developmental and learning delays.
Why is aneuploidy usually only associated with chromosome 21 or the sex chromosomes?
Aneuploidy is often associated with chromosome 21 and the sex chromosomes due to their relatively smaller size and the critical roles they play in development and reproduction. Chromosome 21 is linked to Down syndrome when an extra copy is present, while sex chromosomes (X and Y) can lead to disorders like Turner syndrome and Klinefelter syndrome. The effects of aneuploidy on larger chromosomes tend to be more severe and often result in embryonic lethality, making them less commonly observed in live births. Additionally, the mechanisms of gamete formation and nondisjunction are more likely to affect these specific chromosomes.
Is SARS a prion or viroid?
SARS (Severe Acute Respiratory Syndrome) is caused by a virus, specifically a coronavirus. It is not caused by a prion or a viroid.
This type of error is known as and usually results in zygotes that either do not develop to term or have severe abnormalities.?
This type of error is known as a chromosomal abnormality, which can occur during cell division and lead to an incorrect number of chromosomes in the zygote. Such abnormalities often result in zygotes that either fail to develop to term or develop severe congenital defects. Common examples include conditions like Down syndrome, Turner syndrome, and Klinefelter syndrome, which can arise from these chromosomal issues.
