La diversidad genetica y la introgresion de genes de zebu en la poblacion de bovinos a lo largo de la costa del golfo de Guinea que va desde Togo hasta Nigeria han sido evaluados a partir de 15 marcadores microsatelitares autosomos y un marcador especifico del cromosoma Y. La media de heterocigosis Ho varia de 0,55 a 0,61 y el numero medio de alelos (NMA) de 5,47 a 6,47. Los indices de diferenciacion genetica (Fst) son diferentes entre las cinco sub-poblaciones (P<0,01). Han sido identificados alelos especificos de poblaciones en los loci ILSTS033 (alelo 254) e ILSTS005 (alelo 182) en la sub-poblacion del Togo con frecuencias respectivas de 5,41 y 12,82%. El alelo 226 del locus ILSTS103 esta totalmente fijado (100%) en la sub-poblacion togolesa y casi (98,75%) en la sub-poblacion del valle del Benin. La evaluacion del marcador especifico del cromosoma Y revela la introgresion de genes de zebu en las cinco sub-poblaciones que van de 37,5% en el valle del Benin y en la Meseta Este, hasta 100% en la Meseta Oeste. El analisis de mezcla utilizando el programa STRUCTURE (k=2) confirma las observaciones fenotipicas que indican la introgresion de genes de zebu en el interior de las poblaciones. Variaciones de mezclas han sido observadas entre rebanos al interior de una misma poblacion. Mientras que los animales del valle del Benin presentan un nivel de introgresion de genes de zebu bajo, la sub-poblacion de la Meseta Este parece ser la mas pura.

MATURATION-RELATED CHANGES IN DISTRIBUTION OF LECTIN RECEPTORS IN BABOON (PAPIO ANUBIS) SPERMATOZOA DURING EPIDIDYMAL MATURATION

D. Mburu

Changes in distribution of surface glycoproteins in baboon sperm were studied by lectin blotting techniques. In baboon, several changes in sperm surface occur during epididymal passage. These changes include increased staining of band that was observed with the WGA binding glycoproteins of 140, 80, 52, and 46 kDa; Con A bands of 66, 37, and 26 kDa; and the PNA binding glycoprotein of 114 kDa. A second change was the loss of preexisting band that was observed with RCA binding glycoproteins of 120, 80, 58, 53, 46, and 37 kDa; and the Con A band of 80 kDa. A final change was noted with Con A binding in which six bands of 8, 9, 12, 14, 18, and 21 kDa were added as the sperm matured through the cauda epididymis. These findings present new information on the changes in distribution of surface glycoproteins in baboon sperm during epididymal passage. There was some reorganization of the molecular structure of the sperm during epididymal maturation.
