Answer to Question 1

1 . Nondisjunction during gametogenesis, leading to the formation of an abnormal gamete containing an extra chromosome 21
2 . An extra chromosome 21, acquired as part of a translocation chromosome
3 . Nondisjunction occurring in the zygote.

Answer to Question 2

Alteration of the normal bacterial flora of the vagina following an intensive therapy with broad-spectrum antibiotics. The predominance of the normal bacteria usually holds the fungi in check; once normal bacteria are eliminated, proliferation of fungi will result in disease.
