Question:
What would the offspring be if the genetic material had one x and 2y? Would there be any sort of mutation?


Replies:
This condition is called 47, XYY (47 chromosomes, including an extra Y Chromosome). It occurs at a frequency of about 1 in 1000 among newborn males. Studies suggest that XYY males tend to be taller than average, have a lowered I.Q., and are more likely to be involved in criminal activity (although they are not more violent) than the average male. However, some XYY males are normal in all of these areas. My source is Mangen, and Mange, Genetics: Human Aspects (1980).
