Verified step by step guidance

Understand that in mammals, including sheep, biological sex is typically determined by the combination of sex chromosomes: XX for females and XY for males.

Recognize that the presence of the Y chromosome generally triggers male development due to the SRY gene, which initiates the formation of testes.

Note that an XY chromosome combination means the lamb has one X chromosome and one Y chromosome.

Recall that the Y chromosome carries the genetic information necessary for male sex determination.

Conclude that a lamb with XY chromosomes will develop as a biological male.
