Balancing claims for balancing selection.
Natural selection is expected to leave distinctive signatures on patterns of neutral variation that are tightly linked to a site carrying an advantageous mutation. This notion is the basis for molecular population genetics approaches to the analysis of adaptations in the human genome. In principle, this is an attractive prospect; in practice, several complications and challenges make it difficu...
متن کاملBalancing selection
sophisticated culture of the native North Carolina Algonquian Indians he encountered. In 1585, John White returned from ‘Virginia’ with visions of the perfect place to plant the English in the New World. While Raleigh continued preparations for a permanent colony of 115 men, women and children at Chesapeake, John White was appointed governor. But the project failed for lack of supplies and reli...
متن کاملI-14: Ethical Issues in Sex Selection and Family Balancing
Sex selection for non-medical reasons is a major controversy in around the world. Here in this paper, we presented the ethical arguments about sex selection for non-medical reasons and discuss about them in Islamic context. Significant arguments about sex selection relate to sexism and sex discrimination, sex disproportion, human dignity, playing God, psychological pressure on unselected childr...
متن کاملBalancing Selection: Walking a Tightrope
Combining modern transgenic techniques with fitness measurements and enzyme activity assays, a new study demonstrates a habitat-dependent tradeoff between two alleles of a key detoxification enzyme in fruit flies. The elegant findings provide concrete, elusive evidence supporting a foundational and controversial theory about the maintenance of genetic variation.
متن کاملGlioma Association and Balancing Selection of ZFPM2
ZFPM2, encoding a zinc finger protein and abundantly expressed in the brain, uterus and smooth muscles, plays important roles in cardiac and gonadal development. Abnormal expression of ZFPM2 in ovarian tumors and neuroblastoma has been reported but hitherto its genetic association with cancer and effects on gliomas have not been studied. In the present study, the hexamer insertion-deletion poly...
