It may be noted that the nuclear genome is characterized by homologous pairs of chromosomes of biparental origin. However, the mitochondrial DNA is transferred exclusively from the mother to the offspring without undergoing any recombination as the paternal mitochondrial DNA undergoes degradation during fertilization. It is interesting to note that the organs afflicted by the diseases transmitted through mitochondrial inheritance are skeletal muscles, brain, heart, eye, colon, pancreas, inner ear, liver, kidney and blood.

#The one that is formed from ''majja'' (marrow, or the tissue that fills up bone cavities) which in turn circulates all over the body both in males and females. Reproduction is the function of this second form of ''shukra'' also. Therefore, on careful examination, it seems that the first form of ''shukra'' stands for semen in general and for sperms in particular and, the second form of ''shukra'' stands for hypothalamo-pituitary-gonadal axis of hormones that circulates all over the body. For instance, the GnRH of the hypothalamus stimulates the anterior pituitary to secrete LH which in turn stimulates testes and ovaries to form hormones such as testosterone, estrogen and progesterone. As per  [https://en.wikipedia.org/wiki/Ayurveda Ayurveda] classics, the brain, and thus, the hypothalamus, is obviously a part of ''majja'' which is enclosed in ''mastaka''. [5]
