The Nurse Understands That the Genetic Possibility of a Woman

The nurse understands that the genetic possibility of a woman having a male or a female child is based on the single sex chromosome provided by each parent (mother is XX, father is XY, and each contributes one chromosome). Fill in the boxes below with the possibilities based on the single chromosome that is contributed by each parent in these four possible combinations. For the purpose of this exercise, the mother's chromosomes are designated X(m1) and X(m2), and the father's are designated X(f) and Y(f). The result of any XX chromosome pair yields a girl, and XY a boy.
