Question: 1 / 2700

If a sperm carries a Y chromosome, what will the offspring be?

Male (XY)

When a sperm carries a Y chromosome, it will combine with the X chromosome from the egg to produce an offspring with the genotype XY. This combination determines male sex characteristics. The presence of the Y chromosome is a key factor in the development of male reproductive structures and traits, making the offspring male.

In the context of human genetics, females typically have two X chromosomes (XX), while males have one X and one Y chromosome (XY). Therefore, if the sperm is contributing a Y chromosome, it guarantees the production of a male child when combined with an X chromosome from the mother. Other options, such as only females or neither, do not align with the established principles of chromosomal determination of sex.
