Read the passage given below and answer the following question .
The Meghalaya Succession Act (passed by an all-male Meghalaya legislative assembly) received the President’s assent in 1986. The Succession Act applies specifically to the Khasi and Jaintia tribes of Meghalaya and confers on ‘any Khasi and Jaintia of sound mind not being a minor, the right to dispose of his self acquired property by will’. The practice of making out a will does not exist in Khasi custom. Khasi custom prescribes the devolution of ancestral property in the female line. There is a feeling, specially among the educated Khasi, that their rules of kinship and inheritance are biased in favour of women and are too restrictive. The Succession Act is therefore seen as an attempt at removing such restrictions and at correcting the perceived female bias in the Khasi tradition. To assess whether the popular perception of female bias in the Khasi tradition is indeed valid, it is necessary to view the Khasi matrilineal system in the context of the prevalent gender relations and definitions of gender roles.

The above passage talks about Khasi Tribe. Khasi tribe is_____.

Matrilineal
