- Most partial moles are triploid ( three chromosome sets ).
- In " partial moles " some villi are vesicular, whereas others appear more normal, and embryonic / fetal development may be seen but the fetus is always malformed and is never viable.
- In contrast, a "'partial mole "'occurs when a haploid egg is fertilized by two sperm or by one sperm which reduplicates itself yielding the genotypes of 69, XXY ( triploid ) or 92, XXXY ( tetraploid ).
