<prompt> Karyotype of partial mole is:46 XY69 XXY45 XO46 XXY  <response>: Ans: b 69 XXY Ref: Shaw, 13th ed, p. 250The partial mole demonstrates triploid karyotype 69 chromosomes where as a complete mole is composed of 46 XX and all chromosomes are of paternal origin. This is called androgenesis. The pattern 46XY is infrequent.46 XX - empty ovum fertilized by haploid sperm which duplicates after meiosis.46 XY - two sperms fertilize an empty ovum.FeatureComplete molePartial moleKaryotype46, XX 46,XYTriploid 69, XXYVillous edemaAll villiSome villiTrophoblast proliferationDiffuse; circumferentialFocal; slightAtypiaOften presentAbsentSerum hCGElevatedLess elevatedhCG in tissueBehaviour2 chorio carcinomaRare choriocarcinoma
