Answer:
Aneuploidy refers to the change in chromosomal number 23, which can lead to genetic diseases.
Explanation:
Numerical abnormalities in sexual chromosomal abnormalities involve the loss or gain of a sex chromosome generating aneupliodes individuals. Generally, the loss of chromosomes has a greater impact on an individual than the gain, although this can also have serious consequences.
Within sexual aneuploidies we can distinguish the following:
· Sexual trisomies: it is a common disorder that is usually detected at puberty since there are no characteristic physical features in infants or children. Trisomies are those where an extra sex chromosome is evidenced
§ Klinefelter syndrome, XXY

§ Double Y syndrome, XYY (called superman syndrome)
· Sexual monosomies: Cells that have lost a sex chromosome
§ Turner syndrome, XO
