Abstract
A detailed cytological description of somatic cell divisions, spermatogenesis, and the prophase stages of primary oocytes of Pomphorhynchus laevis Müller (Acanthocephala) is reported. The karyotype (2n = 7/8) is composed of 2 pairs of submetacentric, 2 pairs of subtelocentric with a XO XY sex-determining mechanism. © 1993 Taylor & Francis Group, LLC.File in questo prodotto:
