DNA profiling: DNA profiling is a technique to identify individuals based on unique variations in their DNA sequences.
- While 99.9% of human DNA is identical, the 0.1% variation, especially in Short Tandem Repeats (STRs), forms the basis of DNA profiling, enabling precise identification.
Levirate: Levirate marriage is a custom where the brother of a deceased (or physically incapacitated) man can marry to his brother's widow, ensuring the continuation of the family line.
- It has been practiced in India by several tribes, including the Santhal and Munda.
- During Vedic times, niyoga, the practice of a younger brother or kinsman marrying the widow of an elder brother, was practiced but later disallowed during the Gupta and earlier periods.
Sororate is the custom of a man marrying his wife's sister if his wife dies.
