The paper presented a study on factors influencing the consumer behavior among Saudi women pertaining to online purchase. Hence, this study is conducted to gain a comprehensive knowledge and understanding on the possible factors behind the virtual business transaction. This study involves 34 Saudi women representing diverse background ranging from 18 to 35 years old. The interview survey consists of an open-ended question and analyzed through theme analysis procedure. The study yields interesting findings with both trust (45%) and risk (40%) are found to be the outstanding factors compared to others that affect consumer decision making. Finally, the paper highlights on the recommendation for future research related to online purchase that can be carried out by other researchers.

In an attempt to elucidate the mechanism of sterility of X-autosome translocations in the mouse, we studied the distribution of [3H]-uridine incorporation in sterile males carrying the balanced X-16 reciprocal translocation. The results failed to show an overall reactivation of the X as has been postulated by Lifschytz and Lindsley (1972) but there was some spreading of X inactivation along the translocated and normal chromosome 16 in those regions that were close to the X breakpoint. We feel that this process could be responsible for metabolic disturbances leading to degeneration of primary spermatocytes and, therefore, to sterility.

Silver-stained synaptonemal complexes (SCs) in surface-spread pachytene nuclei from a boar, heterozygous for a reciprocal translocation, were analysed by electron microscopy. In such heterozygotes, cross-shaped quadrivalent configurations are expected to form in order to maximize homologous pairing. Contrary to the classical, expected cross-shaped configuration, heterosynapsis was often observed, with asymmetrical association in the lateral elements of the non-homologous partners of the quadrivalents. This heterosynapsis is assumed to be a mechanism preventing spermatocyte loss, but inducing a secondary segregational type of impairment of fertility due to foetal wastage leading to reduced prolificacy.
