Determine offspring sex based on genes XX and XY chromosomes.py

# The male gametes or sperm cells in humans and other mammals are heterogametic and contain one of two types of sex chromosomes. They are either X or Y. The female gametes or eggs however, contain only the X sex chromosome and are homogametic.

# The sperm cell determines the sex of an individual in this case. If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX or female. If the sperm cell contains a Y chromosome, then the resulting zygote will be XY or male.

# Determine if the sex of the offspring will be male or female based on the X or Y chromosome present in the male's sperm.

# If the sperm contains the X chromosome, return "Congratulations! You're going to have a daughter."; If the sperm contains the Y chromosome, return "Congratulations! You're going to have a son.";
