Chromosomal Numerical Mutations: Triploidy

Chromosomal Numerical Mutations: Triploidy

In biology, chromosomal abnormalities can occur when there is a change in the number of chromosomes in cells compared to the expected normal count. Although changes in structural features like deletions, duplications, translocations, and inversions may also exist, this article focuses specifically on triploidy—a type of chromosomal numerical mutation characterized by three sets of chromosomes instead of the usual two found in most diploid organisms. This anomaly is often described as having one set of paternal chromosomes and two sets of maternal ones, resulting from fertilization errors where a haploid sperm cell with only half the genetic information fuses with a diploid egg containing twice the amount of DNA needed. In humans, triploidy occurs approximately once every 8,000 births.
