Triploidy refers to a condition where an individual has 1.5 times the normal number of chromosomes. Egg and sperm cells are haploid (have n number of chromosomes). Normal cells are diploid (have 2n number of chromosomes). The exact cause of triploidy in humans is not known. It may be caused when more than one sperm fertilize a single egg. Triploidy may be preferred and cultivated in plants in order to increase productivity.

Two YY chromosomes. Which can be triploidy. Don't quote me on this lol

Triploidy is a chromosomal abnormality in which an individual has three sets of chromosomes in each cell instead of the normal two sets. This condition usually results in developmental abnormalities and is often not compatible with life. Triploidy can occur as a result of errors during fertilization or early development of the embryo.

Polyploidy is the condition of some biological cells and organisms.

Karyotypes are able to tell if there are any chromosome conditions present. These condition include Down syndrome, Turner syndrome, Klinefelter syndrome, and Triploidy.
