The coefficient of relatedness is a measure of the proportion of genes that two individuals share due to common inheritance. A mother and daughter would share 0.5 of their genes, a father and son would also share 0.5 of their genes, siblings (brother and sister or sister and sister) would share 0.5 of their genes. However, an aunt and niece would only share 0.25 of their genes, as the niece would have inherited half of her genes from her father (the aunt's sibling) and the other half from her mother, who is unrelated to the aunt.
