{'chromosomes': [4, 1, 0, 1], 'sex chromosome': [0, 1, 1, 0], 'colour blindness': [2, 0, 1, 0], 'mutation': [1, 0, 0, 1], 'mutations': [0, 0, 1, 1], 'autosomes': [0, 0, 1, 0]}

Option 1: This option states that both statements are individually true and statement 2 provides the correct explanation for statement 1.

Option 2: This option also states that both statements are individually true, but statement 2 does not provide the correct explanation for statement 1.

Option 3: This option states that statement 1 is true, but statement 2 is false.

Option 4: This option states that statement 1 is false, but statement 2 is true.

The correct answer is option 2, which means that both statements are individually true, but statement 2 does not provide the correct explanation for statement 1.

Statement 1 correctly states that human beings have 23 pairs of chromosomes, with one pair being the sex chromosome and the remaining 22 pairs being autosomes. However, statement 2 is not the correct explanation for statement 1. While it is true that color blindness is caused by a mutation on the X-chromosome, this does not directly relate to the fact that human beings have 23 pairs of chromosomes, one of which is the sex chromosome.
