A Cytogenetic Analysis of Enteromius parablabes (Daget, 1957) from Aho Stream, Ile-Ife, Nigeria

Open Journal of Genetics 2022年第3期12卷 25-32页

作者： michael olaoluwa popoola Oluwatomisin Awe Idowu Isaac Adeniran Department of Zoology Obafemi Awolowo University Ile-Ife Nigeria

In this study, Enteromius parablabes [1] was analyzed with the aim of providing baseline information regarding the diploid chromosome number and karyotype differences of both sexes. The diploid chromosome number (2n) was 50 for both sexes, and this corresponds to the diploid chromosome number reported for most small African Barbus species. The fundamental number (NFa) of the male and female was 81 and 98 respectively. The first pair of metaphase chromosomes which has been suggested to be a marker for the small African Barbus group was conspicuously larger in the female karyotype. The karyotype of the female consisted more of metacentric (39m + 7sm + 2st + 2t) which is common in the group while the karyotype of the male which consisted more of telocentric chromosomes (10m + 21st + 19T) is scarce. The chromosomal number obtained for E. parablabes demonstrates its diploid status in the context of the ploidy lines characteristic of the African Barbus assemblage.

Karyotypic Analysis of the Clipper Barb Enteromius callipterus (Boulenger 1907) from Tahoss Stream, Jos Plateau, Nigeria

Open Journal of Genetics 2022年第3期12卷 33-41页

The chromosomes of male and female individuals of Enteromius callipterus [1] were assessed in this study with the objective of determining the diploid chromosome and karyotype. The samples were obtained from the Tahoss River, Jos Plateau, and the assessment of the chromosomes was conducted using the conventional Giemsa staining technique. The study reveals that the male individual of E. callipterus has a diploid chromosome number of 2n = 50, the fundamental number of autosomal arms (NFa) of 82, and a karyotype formula of 2n = 14M + 4m + 32t. However, none of the spreads obtained for the female individuals were either equal to or below the common diploid chromosome number of 50 known for members of the genus. The two spreads presented here were of 2n equal to 54 and 58. Although sex dimorphism is rare within the genus, the present results suggest E. callipterus show sexual dimorphism at the chromosomal level.

Abuses of Women in Inheritance Across Cultures： An Exploratory Study of Its Prevalence and Religious Panacea

Chinese Business Review 2017年第12期16卷 620-630页

作者： popoola Sulaiman Akorede Agbabiaka-mustapha Muinat A. michael Otedola College of Primary Education Epe Lagos State Nigeria

The patriarchal nature of African society generally lays emphasis on the superiority of men over women in every sphere of life. When a woman dies, in most African societies, her legacy is usually inherited by the husband, children, and her family. But if a man dies, the widow, usually experiences false accusations of killing her husband to deny her share of her husband＇s properties. This paper examines how the dynamics of cultural practices in Nigeria promotes abuse of inheritance rights of women and discusses the possibilities of using Islamic inheritance rules as a divine solution to the abuse of inheritance rights of women. The research questions as follows： what is the nature of women＇s rights to father＇s estate？ What is the nature of widow＇s right to the husband＇s estate？ What is your perception about the Islamic law of inheritance？ The data for this study were collected using questionnaire and simple percentage was used for the analysis. In this respect, a questionnaire was administered to 220 women who were purposely selected from the three major tribes in Lagos state, Nigeria. The result showed that various cultures in Nigeria favour male child, grant male higher rights to land and other properties and promote abuse of inheritance rights against women.
