Each participant read two different sentences from each sentence quadruplet, one in the first session and the other one in the second session.
During the period under review there have been 3,832,168 nuptial confinements of which 44,072 were twins, 437 were triplets and 8 were quadruplets.
The cell number in those two monozygotic blastocyst quadruplets was similar and varied from 13 to 34 cells.
Because these were three-zygote quadruplets, genetic factors were well controlled.
The sample included 3074 complete twin pairs, 14 complete sets of triplets, one complete set of quadruplets and 1316 individual twins with a non-participating co-twin.
Attempts to produce monozygotic quadruplets in cattle by blastomere separation.
The quadruplets were born at 26 weeks gestation and so their premature status predisposed them to varying degrees of health problems.
As noted earlier, each of the thirty quadruplet sets contained an identity, an inflected, a derived and a control word.
