A world chess champion has curly hair, attached earlobes and freckles. Which one of the following traits is not likely to be passed on to his/her offsprings?

Only traits that are encoded in DNA (genetic traits) are passed on from parents to offspring. Curly hair, attached earlobes and freckles are genetic traits determined by particular genes and can be inherited. Chess skill, on the other hand, is an acquired ability learned through training and practice during the individual's lifetime; acquired characteristics are not inherited (as established since the rejection of Lamarckism). Therefore, chess skills will not be passed on to the offspring.
