The Most Common Type of Polyploidy in Humans is ____

Question

The most common type of polyploidy in humans is ____.
A) trisomy
B) monosomy
C) triploidy
D) tetraploidy
E) haploidy

Accepted Answer

Triploidy, or having three copies of each chromosome, is the most common form of polyploidy in humans. This condition results in 69 chromosomes instead of the typical 46 and is usually fatal early in development. Trisomy (having an extra copy of one chromosome) is also a type of polyploidy but is less common than triploidy. Monosomy, tetraploidy, and haploidy are not forms of polyploidy.
