Correct. The womans ova are not responsible for determining a childs sex as they carry only X chromosomes.

  1. The sperm cells all carry the X chromosome. The ovum contains both the X and Y so it is the ovum that determines the sex of the offspring.

Incorrect. The sperm cell determines the sex of the offspring because it either carries the Y or the X chromosome.

  1. The ovum and sperm cells both carry X chromosomes. The placenta carries both the X and Y and it determines the sex of the offspring.
  2. The ovum and the sperm cells both contain the X chromosome. During the course of fertilization either an X or a Y will be created, which determines the sex of the offspring.

  2. Androgen is a hormone that causes disorders to occur
  3. If the Y chromosome does not develop properly, the genes on this chromosome cannot prevent the disorder from occurring

Incorrect. If the X chromosome contains the recessive gene for the disorder, the Y chromosome does not have the genes to counteract the gene on the X chromosome.

  1. Why are males more susceptible to X linked disorders?
  2. Because males have an XX pairing of chromosomes; therefore, this increases their odds of a disorder.
  3. Because males have an XY pairing of chromosomes and the Y chromosome is more likely to host a genetic disorder.
  4. Because most genetic disorders are connected to the dominant gene and since men have an XY pairing a disorder is more likely to be expressed.
  5. Because males have one X chromosome and if a recessive gene for a disorder is present he does not have another X chromosome that may contain a dominant gene to block its expression.

  3. Hemophilia is an X-linked disorder and it would be impossible for him to pass it to any male offspring. It would be possible for his female offspring to be carriers though.

Correct. Since his male offspring would inherit his Y chromosome, he cannot pass along an X-linked disorder to them.
