In humans, most (the 22 pairs of autosomes) are shaped like an X, but there is also one pair of sex chromosomes, named X and Y. XX is female, and XY male.

Is it true that a person who inherits two X chromosomes will be a male?
Answer:This is not true. If you inherit two X chromosomes you will be a girl. A boy has a X and a Y chromosome. I don't know for sure, but I think so. After all, the numbers xs are greater than ysAnswer:No, it isn't. A person with XY chromosomes is male. Two X chromosomes is female.Answer:It is possible but they have to inherit a Y chromosomes. It called Klinefelter's syndrome (KS). KS has two X chromosomes and one Y chromosome. They can grow breast and have an ovary and have anger problems. Most men like this in up in prison.
Why can't boys be carriers of colorblindness?
With sex linked traits (the allele is found on the X chromosome) males are either affected or not (they have the defective allele or they don't). Women have two copies of the allele and can be a carrier.
If a male donates a Y chromosome and the female donates an X chromosome what is the sex of the child?
We are learning new theories of gender/sexual preference every day as a result of more advanced studies. Until recently, however, it was generally accepted that a sperm with a y chromosome would produce a male child and a sperm with an x chromosome would produce a female child. Biologists have discovered that things may no longer be quite that simple in some cases. For example, traditional wisdom says that boys have an X and Y chromosome pair and that girls have an X and X pair. They have learned that in cases of gender identity, some men are born with an extra X, sometimes even two extra Xs. In such a scenario, their gender chromosomal makeup can be XXXY, weakening the Y (male) sequence enough to cause gender confusion. The same is true of girls. Sometimes, they are born with only one X in the chromosomal pair which can result in more masculine traits. But until these studies are more broadly accepted, it is fairly safe to say, that the Y half of a chromosome pair will result in a male offspring.
Why more x linked disorders than y linked disorders?
Odds favor X-linked diseases because everyone has a least one X chromosome as opposed to a Y which only 50% (males) have. Since women have two Xs, they are less affected by X-linked diseases too, because they have likely inherited one perfect X from one parent and one damaged X from the other, where a man only has one X from his mom so if it's damaged he's going to have the disease expressed when his sister might not or have a milder version of the same disorder.

Who has y chromosomes?
In humans, males have one Y chromosome and one x chromosome in addition to 44 other chromosomes, females have two Xs. Because of errors in gamete (egg or sperm) production, some humans have XYY, XXY, or some other combination of sex chromosomes.
All paired chromosomes which are similar within an organism are called autosomes?
Autosomes are the non-sex chromosomes. The 23rd pair is the sex chromosomes. Autosomal homologous pairs are all shaped like Xs. The sex chromosomes, as we know, can either be XX or XYType your answer here...
What is the difference between a bar graph and a line plot?
The difference is that there is no y axis on a line plot. The letter X is used to represent one of that number. For example, if there where 2 people that had two pets, there would be two Xs above the number 2. A bar graph uses the scale on the y axis to tell you the amount, instead of Xs. I hope this helps!
Which best describes chromosomes in humans?
Humans have 22 pairs of homologous non-sex chromosomes (called autosomes), and one pair of sex chromosomes, making a total of 46 chromosomes in a genetically normal human.Each member of a pair is inherited from one of the two parents. In addition to the 22 pairs of homologous autosomes, female humans have a homologous pair of sex chromosomes (two Xs), while males have an X and a Y chromosome.
