RESUMO
This paper is a brief account of the scientific work of J.B.S. Haldane (1892-1964), with special reference to early research in Human Genetics. Brief descriptions of Haldane's background, his important contributions to the foundations of human genetics, his move to India from Great Britain and the research carried out in Human Genetics in India under his direction are outlined. Population genetic research on Y-linkage in man, inbreeding, color blindness and other aspects are described.
RESUMO
Chronic health effects are increasing in the world such as cancers, hormonal, reproductive, nervous, or immune diseases, even in young people. During regulatory toxicological subchronic tests to prevent these on mammalian health, prior commercialization of chemicals, including pesticides and drugs, or GMOs, some statistically significant findings may be revealed. This discussion is about the need to investigate the relevant criteria to consider those as biologically significant. The sex differences and the non linear dose or time related effects should be considered in contrast to the claims of a Monsanto-supported expert panel about a GMO, the MON 863 Bt maize, but also for pesticides or drugs, in particular to reveal hormone-dependent diseases and first signs of toxicities.
