In biology, why do we have terminologies in terms of female relatoinships such as daughter cells and sister chromatids and not in terms of male relationships. When did this custom started and is there a reason for it ?
During the days when philosophers used to debate, they tended to regard reproduction as a feminine trait. So naturally organisms/cells capable of producing offspring are also given a feminine trait. The parent cell is often called the mother cell, and the daughter cells are so named because they eventually become mother cell themselves.
I presume there exists a similar argument for sister chromatids, in that they are identical. When they separate, they are usually termed as undivided chromosomes.
