Most characteristics 195 develop long before birth but some such as hair and eye, colour, etc.196 may not appear until shortly after birth. Some, such as, amaurotic idiocy (balatva or mandatva) 197 becomes evident in early childhood and still others, such as, cough, phlegm, bending of the body, feeble sense-orgads etc, develop only after the individual has attained maturity.
“The inheritance of mental ability or intelligence is one of the most important, yet one of the most difficult problems of human genetics'199. The reference to the mental capacities of people forming a continuous series from idiot (manda or Jada ) to genius (manişi )200 suggests that “intelligence is inherited by a system of polygenes”201 brought about by Karma,202 other evidence203 substantiates this hypothesis.
Modern Biology explains that “The inheritance of feeble-mindedness is due to a single recessive gene". 204
"It is now evident that the inheritance of mental defect is much more complex. Feeble-mindedness may be caused by diseases205 or by other environment factors, 206 but the majority of cases are due to inheritance" 207
