Genetics are traits such as hair color, eye color, or skin tone that Sims have, and can pass to their children.

Thats the reason why your hairline, height or eye color can be drastically different from your siblings. Math is a way of solving problems by using numbers and equations.

Later in life, melanin stops being produced and hair turns grey and white. If the MC1R gene does not function (i.e., it is blocked or inactivated), the melanocytes will produce pheomelanin instead of eumelanin. Eumelanin genes are not recessive or dominant, but either "off" or "on" The more "on" genes a baby gets from either their mother or father, the darker that baby's hair color. They found that some of the 8 genes identified as having a role in red hair work by controlling when the MC1R genes is turned on or off.

Biology and genetics of hair. Westgate, G, et al.
