A simple cytogenetic examination of the abnormal pronuclear stage would have been helpful to decide at least whether the number of whole chromosome sets has increased (the chromosomal constitution should then be in the pentaploid range) or whether an approximately diploid constitution is present.

Udensi & Ntui (2013) observed that when the induced polyploidy is a mixoploid, it could either be a diploid+triploid (2n+3n) or diploid+tetraploid (2n+4n) and if tilts towards the former, there is every likelihood of aborted process as affirmed by Meng & Finn (2002) that fertility is often poor if the hybrid is triploid, pentaploid,or an aneuploid with a chromosome number less than hexaploid.
