Monozygous cattle twins as a result of transfer of a single embryo.
A single embryo obtained from a superovulated Holstein-Friesian cow resulted in female twins following transfer.Blood typing studies including 17 genetic systems showed that the twins had identical genotypes. The probability that dizygous female twins from the same parents have identical blood types by chance was calculated as 1.34 x 10(-7).
