Note on Mendelian Heredity in Cotton

Non-Mendelian epigenetic heredity: gametic RNAs as epigenetic regulators and transgenerational signals.

Inheritance of epigenetic variations may account for a significant part of heritability in human and in mammalian models. Heritable epigenetic variations were reported in plants under the name 'paramutation' more than 50 years ago. Reports by E. Whitelaw and her colleagues and by our laboratory now describe a variety of situations resulting in epigenetic inheritance in mouse systems. In the thr...

Radiation effects on human heredity.

In experimental organisms such as fruit flies and mice, increased frequencies in germ cell mutations have been detected following exposure to ionizing radiation. In contrast, there has been no clear evidence for radiation-induced germ cell mutations in humans that lead to birth defects, chromosome aberrations, Mendelian disorders, etc. This situation exists partly because no sensitive and pract...

Effect of cropping system on cotton biomass accumulation and yield formation in double–cropped wheat–cotton

Wheat–cotton double cropping practices on a large scale in cotton belt of the Yellow RiverValley and the Yangtze River Valley in China. Field experiments were conducted to determinethe effects of wheat–cotton double cropping on cotton biomass accumulation and yieldformation during 2011/12 and 2012/13 growing seasons. Two cotton cultivars, Siza 3 (mid–latematurity) and CCRI 50 (early maturity), ...

Heredity in Ichthyosis

A case of advanced ichthyosis was recently admitted into the Windham Hospital. The family history as far as it could be elicited made it apparent that it was a disease of the males in the family transmitted through the females, the latter being immune. The patient's elder brother was suffering from the same disease, while his sisters were all free; his father did not suffer from it, nor his gra...
