To determine the correct answer, let's go through each of the options.

Option 1: All males have a Y chromosome, and females do not.
This statement is not entirely accurate. While it is true that males have a Y chromosome, females also have a sex chromosome called the X chromosome. So this option is incorrect.

Option 2: All males have an X chromosome, and females do not.
This statement is also incorrect. Both males and females have X chromosomes, but the key difference is that males have one X and one Y chromosome, while females have two X chromosomes. So this option is incorrect as well.

Option 3: All males have 47 chromosomes, and females only have 46.
This statement is incorrect. Both males and females typically have 46 chromosomes each, consisting of 22 pairs of autosomes and one pair of sex chromosomes.

Option 4: All males have 46 chromosomes, and females have 47.
This is the correct answer. Generally, human males have 46 chromosomes, including 22 pairs of autosomes and one pair of sex chromosomes (XY). On the other hand, human females have 46 chromosomes, including 22 pairs of autosomes and one pair of sex chromosomes (XX).

Therefore, the correct answer is: All males have 46 chromosomes, and females have 47.
