  "A female's egg contains two X chromosomes. The male sperm cell has an X and a Y."

  This statement is completely wrong. As any high school biology student could tell you, this would be true for normal (Diploid) cells in females and males, but it is not true for mature gametes, which are haploid.

  In other words, the female's egg contains only one X chromosome. The male sperm cell has either an X or a Y, but not both.

  Technicaly wrong I am proof to an exeption of this. I am XXY

  It makes me sad that I wouldn't have caught the error. After a little reminding, I realized. . .One of the things I hate the most about being brought up as a jW is my fear of what science would tell me. I think I knew instinctively that blind faith would be impossible with any education in that area, and lets face it, as a JW, you need all the blindness you can muster up!

  Males usually (under normal circumstances) have XY pairings. Females have XX pairings.

  Assuming Jesus was a real person, he should have had an XY pairing. It is practically unheard of for someone to have only a Y chromosome.

  Here's an interesting site that describes some syndromes involving abnormal numbers of sex chromosomes: http://anthro.palomar.edu/abnormal/abnormal_5.htm

  No it's not unheard of it's impossible. There is not enough something or other on the Y chromosome for life to form.

  Not too many people know this, but even though female cells do indeed have 2 X-chromosomes, actually only 1 is active. The other one is trashed early on in the Embryo stage.

  From Wikipedia:
  Early in embryonic development in females, one of the two X chromosomes is randomly and permanently inactivated in nearly all somatic cells (cells other than egg and sperm cells). This phenomenon is called X-inactivation or Lyonization, and creates a Barr body. X-inactivation ensures that females, like males, have one functional copy of the X chromosome in each body cell. It was previously assumed that only one copy is actively used. However, recent research suggests that the Barr body may be more biologically active than was previously supposed. [4]

  If you ever see a calico cat, the 2 different colours of the fur are caused by some cells having the X-chromosome of the mother deactivated while the other colour fur has the X-chromosome of the father deactivated.

  This is a blatant error that most people would not catch. Why? Because they are thinking of regular cells. A regular cell has at least one X, and either another X or a Y, chromosome in position 23. They have a total of 46 chromosomes (except in abnormalities, where there could be missing or extra chromosomes, including extra sex chromosomes).

  Most people do not think about the eggs and sperm. Each only has one of each pair (the other supplies the missing chromosomes upon fertilization). The egg always has an X chromosome under normal circumstances; in rare conditions it can have an extra or missing, or even a Y chromosome. These children will be born defective. The sperm has about equal chance of having an X or a Y, which pairs with the X in the egg to produce the XX or XY. Again, in abnormal circumstances, it is possible for the sperm to have extra or missing chromosomes which will produce a genetic defect.

  I believe the writers of that article in the Puketower and Asleep publications ought to go to college. This is the sort of "errors" that I wonder if they actually are because of stupid people writing up the magazines (and to think your life depends on the accuracy of them), or if they are put there on purpose in order to disrupt integrated thinking. Anyone who believes it will be confused when other puzzle pieces come in, since there is a bad piece. And, if they are confused, they fall prey to other Watchtower superstitions. And this is a basic fact, that most biology students learn in the 10th grade (that is, unless they are too tired from the Theocraptic Misery "School(??)" and Circus Meeting.)

  DOESN'T THIS INSULT JEHOVAH WHEN THEY GET THINGS WRONG LIKE THAT?

  This reminds me of another quote I heard from the platform by a brother on the hospital liason committee. He was giving a talk on blood and how blood can save your life. He was including lots of biology and information about the use of blood in medicine. He started talking about stem cell research and how it is scripturally wrong also as "stem cells originate in the blood". Everyone in the audience is nodding in agreement. I was studying biology at the time and wanted to yell out, "No! They don't!" Stem cell's are often harvested from the blood found in umbilical cords but they do not originate in the blood. All cells originate from stell cells including blood cells. I had to satisfy myself with venting to my husband on the way home in the car.

  I so love university where even a mere foolish and easily deceived woman such as Eve myself could immediately put up her hand and ask the most learned biology professor who made such a statement, to please explain why his statement differs from the established biology text?
