A blastocyst does not have a gender.
A blastocyst is a very early stage of an embryo, formed about 5-6 days after fertilization. At this stage, the embryo is still developing and hasn't yet formed the sex organs that determine gender.
Gender is determined by the presence of either the X or Y chromosome. A blastocyst contains genetic material from both the mother and father, including the sex chromosomes. If the blastocyst contains an X chromosome from the father and an X chromosome from the mother, the embryo will develop as female. If the blastocyst contains a Y chromosome from the father and an X chromosome from the mother, the embryo will develop as male.
However, the sex chromosomes are not expressed until later in development, and the blastocyst itself does not have any observable features that indicate gender.
It is important to note that the development of a blastocyst into a fetus is a complex process that can be affected by many factors.
