A 20-year-old pregnant female gives birth to a stillborn child. Autopsy reveals that the fetus has 92 chromosomes. What term may be on the autopsy report to describe this condition?

The normal chromosomal number of human cells is 23 pairs or 46 chromosomes, which is a diploid state (2n). However, chromosomal disorder can occur in which there will be a less or more than this chromosome number in human cells. This could be as a result of mutation in the genome.

In this case, the stillborn baby was diagnosed to have 92 chromosomes which is far more than the normal 46 chromosomes. The chromosome number in a human gamete is 23, haploid (n). In this case, the baby is found to have a 4n chromosomal state, which is referred to as TETRAPLOIDY, a type of polyploidy in which four copies of each chromosome is present in each cell.
