... If chromosomes fail to separate properly during meiosis, the gametes (sex cells) will not end up with the right number of chromosomes. Later on during fertilization if the egg or sperm contains one of these abnormal gametes, a nondisjunction can occur. If a zygote ends up with one extra chromosome, ...

Polymorphic loci are usually defined as having the most frequent allele at a frequency of less than 0.99 or less then 0.95. Monomorphic: Lacking genetic diversity. A locus in a population i ...
