(D) In humans,sex determination is based on the type of sperm that fertilizes the egg. The father produces two types of sperms: $50\%$ containing the $X$ chromosome and $50\%$ containing the $Y$ chromosome. The egg always contains an $X$ chromosome. If an $X$-bearing sperm fertilizes the egg,a daughter $(XX)$ is born,and if a $Y$-bearing sperm fertilizes the egg,a son $(XY)$ is born. The birth of five daughters is a matter of probability; each fertilization event is independent,and by chance,an $X$-bearing sperm fertilized the egg in every instance.
