Table 1.

Developmental potential of parthenogenetically activated embryos derived from oocytes with different phenotypes and mtDNA profiles

Phenotype	mtDNA profile	No. oocyte	Cleaved (%)*	No. (%)* embryo developed to
Phenotype	mtDNA profile	No. oocyte	Cleaved (%)*	8-Cell	Morula	Blastocyst
Bos taurus	Bos taurus	89	81 (91.0 ± 2.2)^a	38 (42.7 ± 4.8)	27 (30.3 ± 42.0)	27 (30.3 ± 2.0)^a
Bos taurus	Bos indicus	65	63 (96.9 ± 3.1)^a	25 (38.5 ± 5.1)	23 (35.4 ± 2.8)	19 (29.2 ± 1.6)^a
Bos indicus	Bos indicus	49	21 (42.9 ± 12.1)^b	n/a	n/a	4 (8.2 ± 4.5)^b

*Percentages calculated from the number of oocytes that cleaved and developed to each stage. Values are mean ± SEM

Embryos were generated from three cohorts of Bos taurus oocytes with a Bos taurus mtDNA profile and Bos indicus oocytes with a Bos indicus mtDNA profile and four cohorts of Bos taurus oocytes with a Bos indicus mtDNA profile

Different superscripts within a column indicate significant differences (P < 0.05, ANOVA with Duncan’s multiple range test using SAS version 9)
