"WebA euploid zygote can be produced if the aneuploidy is reciprocal: one polar body has an extra chromosome and the other lacks the same chromosome (see also uniparental disomy ). If the extra chromosome is absorbed into a polar body rather than being passed into the oocyte, trisomy can be avoided. " - How many chromosomes do zygotes have
