INHERTANCE IN MAN Some of the phenomena in human inheritance have been observed by the Jainācāryas. Some principles apply to the inheritance of human traits as are suggested by the study of Jaina Biology and Daśadaśās (ten stages of life ).2
The Inheritance of Physical Traits :
The study of some evidences in the Jaina works suggests that the development of each organ of the body is regulated by a large number of genes3 (units of inheritance). The age at which a particular gene expresses itself phenotypically may vary widely as is suggested by ten daśās (stages of human life.
Most characteristics5 develop long before birth but some, such as, hair and eye colour, etc.6 may not appear until shortly after birth. Some

(i.e. skeleton ), marrow of the bone, hair on head, beard, hair on body and nail from the father. Besides it inherits five sense-organs, circulatory and respiratory systems, excretory system, endocrine system, digestive system, nervous system,
etc. See Tandula Veyaliya 1, 2, 3, 16. 2. “Āuso ; evam Jāyassa Jamtussa kámeņa dasa dasă evamahjjamti tańjahā - Balā
