An organism has 6 chromosomes (2n = 6) or 3 pairs of homologous chromosomes. assuming no crossing over occurs, how many different combinations of maternal and paternal chromosomes would be possible in its gametes? remember that each gamete will contain three chromosomes, and each of these will be either maternal or paternal. (denote maternal chromosomes m1, m2, m3 and paternal chromosomes p1, p2, p3.) list the possible eight combinations. (remember the formula is 2n, so in this case 23 = 8.)
