Show Hair and Heredity. Gertrude and Charles Davenport, connected with the Carnegie Institution's Institu-tion's station at Cold Spring Harbor, N. Y., writing In the American Naturalist Nat-uralist of tfie results of their observations observa-tions on the "Heredity of Hair Form in Man," say It is now pbsslble to predict pre-dict from the hair of parents tho form of their children's hair, whether straight, wavy, curly or frizzy. They find that tho following rules are almost al-most invariable: "Two blue-eyed, straight-haired parents will have only blue-eyed, straight-hatred children. Two wavy-haired parents may have straight, wavy or curly-haired children, chil-dren, but the chances of curly hair aro slight. Two curly-haired parents, may have children with cither straight, wavy or curly hair, and the proportion propor-tion of curly-haired offspring will probably prob-ably be large." |
