what difference would there be in the product cells at telophase II of the meiosis if there had been one crossing over at a position half way betwwen the huntington disease gene and the centromere from one pair of autosomes (chromosome 4)has a short arm and a long arm on the short arm is a gene for huntingtons disease (H) AND ON THE LONG ARM is a gene for red hair(R)
