D meaning in Academic & Science ?

A daughter is a female offspring; a girl or woman in relation to her parents. Daughterhood is the state of being someone's daughter. The male counterpart is a son. Analogously the name is used in several areas to show relations between groups or elements. From biological perspective, a daughter is a first degree relative. The word daughter also has several other connotations attached to it, one of these being used in reference to a female descendent or consanguinity. It can also be used as a term of endearment coming from an elder.

In patriarchal societies, daughters often have different or lesser familial rights than sons. A family may prefer to have sons rather than daughters and subject daughters to female infanticide. In some societies it is the custom for a daughter to be 'sold' to her husband, who must pay a bride price. The reverse of this custom, where the parents pay the husband a sum of money to compensate for the financial burden of the woman and is known as a dowry. The payment of a dowry can be found in societies where women do not labour outside the home.
