During gametogenesis, if
nondisjunction occurs in meiosis II (meaning that that at least one pair of
sister chromatids did not separate), the resultant effect will be two cells that
has the normal haploid number of chromosomes (n), one cell that has an extra
chromosome (n + 1), and one cell that has one missing chromosome (n - 1). In
summary, two of the gametes will be n, one will be n + 1, one will be n — 1.
Answer: Directional selection occurs when individuals with traits on one side of the mean in their population survive better or reproduce more than those on the other. ... Directional selection does the “heavy lifting” of evolution by tending to move the trait mean toward the optimum for the environment.
