Micronucleus- injected (embryos generated from enucleated oocytes injected with one micronucleus and parthenogenetically activated), Parthenogenetic (parthenogenetically activated oocytes), IVF (embryos generated by in vitro fertilization). %: percentages over total embryos. Euploid: haploid + diploid. Others: tetraploid + mixoploid + aneuploid.
^a,b:Values with different superscripts in the same column significantly differ (p≤0.05).
