Compare the effects of a disorder caused by
chromosomes failing to separate during
meiosis, such as Patau syndrome, to the
effects of chromosomes failing to separate
during mitosis.
When a mutation occurs during meiosis, the
organism in which the mutation occurs is not
affected. However, the disorder will be
passed to their offspring. Since all the cells in
the offspring begin with the two parental
gametes, every cell in the body of the
offspring will contain the mutation.
When a mutation occurs during mitosis, the
organism in which the mutation occurs is
affected. However, the mutation will only
occur in the localized region in which the
mutated cell is found. It cannot be passed to
offspring.
