The more complex the specific pairing configuration (i.e., quadrivalent [A[B.sub.d] and [R.sub.c][R.sub.q] heterozygotes], trivalent [all parental-[R.sub.c] or [R.sub.q] heterozygotes], or bivalent[s] [parentals and "R" chromosomal homozygotes]), the greater the expected increase in aneuploidy.
In contrast to the pairing difficulties associated with the A[B.sub.d] quadrivalent, trivalent formation in parental/recombinant heterozygotes was similar to that described for other simple Robertsonian rearrangemerits in S.

This may result from associations between the trivalent elements and sex-chromosomal elements during prophase I.
