Leptysma argentina is polymorphic for a centric fusion between pairs 3 and 6 of the basic complement, for interstitial (Si) and proximal (Sp) supernumerary segments in the smallest member of the complement, and for a B-chromosome. Fusion 3/6 is associated with several effects that would lead to a drastic reduction of recombination (Colombo 1987, 1988). Nine populations from the Argentine provinces of Buenos Aires, Entre Ríos and Santa Fe were analysed for total (T), proximal (P), interstitial… CONTINUE READING
