Mendel's work and its rediscovery: A new perspective

Genetics textbooks have been remarkably unaffected by the discovery of fraud in the work of British psychologist Sir Cyril Burt or by the resulting critical review of other classic studies on the genetics of intelligence. Although Burt's name has nearly vanished from current textbooks, his results continue to be cited in textbook discussions of the heritability of intelligence, as do the results of other studies now recognized as methodologically inadequate. Moreover, genetics textbooks consistently employ confused or misleading definitions of the concept of heritability that, together with the reporting of discredited data, perpetuate a fundamentally inaccurate understanding of the genetics of intelligence. This situation is largely attributable to the practice-generic to textbook writing but in this case taken to an extreme-of authors' liberal borrowing from one another or from a few apparently authoritative works (including earlier textbooks). The extent to which authors rely on these sources for their...

Textbook Treatments of the Genetics of Intelligence

Histolpathological and biochemical effects of chloroquine phosphate were investigated. Rats weighing 180-200g selected from the animal stock of Anatomy department, University of Calabar, Nigeria were randomly divided into three groups (1, 2 and 3). Groups 2 and 3 received 2mg/kg and 4mg/kg body weights of chloroquine respectively for 4 weeks. Group 1 animals served as control and were given normal saline in place of the drug. All the animals had free access to rat chow and tap water during the period of the experiment. Seminiferous tubules of the treated groups were shrunken compared to control. There was degeneration of the interstitial tissues and associated loss of interstitial cells of Leydig. Poorly developed spermatozoa were lying freely in the lumen of the seminiferous tubules accompanied with cell debris. We observed decrease in the diameter of the seminiferous tubules and development of necrospermia. Sertoli and Leydig cells were found to have regressed in the test groups. Biochemical observations revealed an increase in the tissue activity of alkaline phosphatase and serum glucose concentration. Treatment of experimental animals with 2mg and 4mg/kg body weight significantly reduced the level of DNA and RNA when compared to those of controls. These findings seem to unfold the toxicological implication of chronic application of chloroquine phosphate treatment on male reproductive organ.
