Daughter

A daughter was a female offspring to her parents. The male equivalent was a son. (TV: An Unearthly Child et al.)

After her death, the First Doctor said that he would always remember Katarina as one of the daughters of the Gods. (TV: The Daleks' Master Plan)

The Tenth Doctor unwillingly had a daughter named Jenny when his DNA was extracted during the Human-Hath War on the planet Messaline by a progenation machine. After initially appearing to have been killed by a gunshot wound, she survived and went on to explore the universe like her father. Despite being the only other known member of the Doctor's species, she did not regenerate. (TV: The Doctor's Daughter)

Some of the Doctor's companions had daughters, such as Amy Pond and Rory Williams, who were the parents of Melody Pond, (TV: A Good Man Goes To War) and Donna Noble, who was mother to Rose Noble. (PROSE: We Are Family)
