Question 4

In 1875,Charles Darwin reported on a family group living in what is now Pakistan that had a condition known as ectodermal dysplasia,which results in few teeth and inactive sweat glands.Darwin wrote that "…no instance has occurred of a daughter being affected...though the daughters in the above family are never affected,they transmit the tendency to their sons: and no case has occurred of a son transmitting it to his sons.The affection thus appears only in alternate generations,or after long intervals."
