The random alignment of maternal and paternal homologous chromosomes during metaphase i is one of the ways genetic variability among gametes comes about. for example, it is possible for an organism with 4 pairs of homologous chromosomes to produce gametes with up to 16 different combinations of maternal and paternal chromosomes. in the case of humans with 23 pairs of chromosomes, there are over 8 million possible combinations. how many possible combinations of maternal and paternal chromosomes are possible in the gametes of an organism with a diploid number of 16 chromosomes ?
