Daughters receive their X-chromosome from their

Explanation

In Biology, every human cell has 23 pairs of chromosomes, one of which is the sex chromosome. Females have two X-chromosomes, while males have one X-chromosome and one Y-chromosome. The question is asking where daughters receive their X-chromosome from. The answer is Option A, which is the father. This is because the father contributes one of his two sex chromosomes to his offspring during fertilization. Since females have two X-chromosomes, they receive one X-chromosome from their father and one from their mother. On the other hand, males receive one X-chromosome from their mother and one Y-chromosome from their father. It is important to note that the sex chromosome determines the gender of a person. Additionally, genetic disorders such as hemophilia and color blindness are caused by mutations on the X-chromosome.
