A man in a striped shirt is explaining a diagram on a whiteboard. The diagram appears to illustrate concepts related to kinship or inbreeding. The whiteboard shows lettered nodes (A, B, C, D, E, F, G, H, I, J, K) connected by lines, with numerical values (100, 50, 25, etc.) and calculations beside them. The man is pointing to a specific section of the diagram on the right, highlighting a path from node E to node A.
