Explore why some families only have boys, focusing on the role of chromosomes in determining gender.
0 views
The gender of your children is determined by chromosomes contributed by the father. Sperm carries either an X or Y chromosome. If a sperm cell carrying a Y chromosome fertilizes the egg, the result is a boy (XY). If it’s an X chromosome, the result is a girl (XX). The distribution is random, so having only boys is a matter of chance.
