They increase the permeability of the lymph capillaries. Interstitial fluid enters the lymphatic vessels through the mini valves (which are overlaps of endothelial cells
from multiple lymph capillaries). The valves also prevent the backflow of the lymph from the vessels back to the tissues.

Explanation:
Hardy-Weinberg principle can be illustrated mathematically with the equation: p2+2pq+q2 = 1, where 'p' and 'q' represent the frequencies of alleles. ... The principle behind it is that, in a population where certain conditions are met (see below), the frequency of the alleles in the gene pool will be constant.
