In your fifth grade science class, one of your students asks, "Why am I a boy?" How might you explain to your fifth grade class in very simple terms how sex is determined?
What will be an ideal response?
Scientists have numbered the chromosomes according to genetic material contained in each pair. The 23rd pair of chromosomes determines the sex of the developing baby. In male zygotes, the 23rd pair of chromosomes consists of one elongated mass called the "X" chromosome, and a "Y" chromosome that is shorter and smaller in mass. In female zygotes, the 23rd pair consists of two X chromosomes. The chromosome pair that the zygote receives (by the joining of the sperm and ova) depends upon the specific sperm cell that fertilizes the egg. The egg always contains an X chromosome. The sperm cell may contain either an X or a Y chromosome. In other words, the father's sperm determines whether a baby is a boy or a girl.
