A person with Klinefelter's syndrome typically has an extra X chromosome, resulting in a genetic makeup of 47,XXY instead of the typical 46,XY for males. Despite having two X chromosomes, they are classified as male due to the presence of a Y chromosome, which carries the SRY gene responsible for male sex determination and the development of male reproductive structures. This genetic configuration influences their physical and hormonal characteristics, leading to male phenotype traits. However, individuals with Klinefelter's may experience variations in secondary sexual characteristics and fertility.
Homologous chromosomes are pairs of chromosomes containing genes for the same traits at the same locations, one inherited from each parent. During meiosis, homologous chromosomes separate and recombine to create genetic diversity in offspring. They help ensure that the proper number of chromosomes is passed on to the next generation.
In a single cell, it would be theoretically possible, though how well it would actually work is debatable. In a person... no. You would literally have to perform trillions of individual surgeries, one for each cell in the body. And that's assuming it would actually do anything. The result would likely be something resembling hamburger.
There's not really a number. Its complicated. The 23 chromosome pair is the gender one. If you're female, you have two X chromosomes. If male, an X and a Y. There's really only that. If you want to be technical, every sperm in the body does has an X-chromosome, but I highly doubt that's relevant
Turner's syndrome is caused by a missing or incomplete X chromosome. Since the gene for red-green color blindness is located on the X chromosome, if the girl inherited the X chromosome carrying the red-green color blindness gene from her father, she could have the condition even though her father has normal vision. Her mother would be a carrier of the gene, but with two X chromosomes, she likely does not exhibit red-green color blindness herself.
Klinefelterâ??s syndrome is the result of additional X genetic material in males and typically causes low testosterone levels, gynecomastia, and infertility. Though there are no documented famous people with this syndrome, some believe that George Washington may have been afflicted.
No, as people with Klinefelter's syndrome cannot have children and so there would not be another generation. (That is not entirely true, while it is true Klinefelters causes an extra chromosome sperm maybe be found via a testicular extraction in minute amounts. If this is the case you can father a biological child though the chances are small it is not impossible and more and more Klinefelter men are becoming dads. We can also adopt, and while I understand the authors point - the child would be ours and therefore carry our name and continue the generation. Klinefelters IS NOT hereditary. Hope this helped.
It probably means that the boy has a disease known as Klinefelters. They have two x chromosomes and one y. This will make the boy have a more feminine appearance even though the boy is a guy from genetic makeup.
A person with Triple X syndrome (or Poly-X syndrome)is a woman; hence the fact that they have all "X" chromosomes, versus 1 "X" and 1 "Y" (XY), which would be a male. The difference is that during cell reproduction they manage to get an extra "X" chromosome, thus giving them 3 "X" chromosomes(XXX) in some, but not all, of their cells. A normal female karyotypewould only have 2 "X" chromosomes (XX).Usually, there are no visual symptoms and the disease cannot be recognized just by looking at the person. A woman with Triple X tends to be tall and thin. Most are not mentally retarted (though in rare cases, they can be), butmost usuallyhave reproductive and mentrual difficulties/problems.More info at: http://en.wikipedia.org/wiki/Triple_X_syndromeHope this helps! ;)
Each person has 23 pairs of chromosomes, in total they have 46, though in science fiction a fictional 24th pair of chromosomes created a super-race that healed faster, and were stronger. Downs Syndrome is caused by having 47 chromosomes total, which means that the person has an extra chromosome on pair 21.
Some symptoms include intellectual disability, hypothyroidism, and heart defects. Some characteristics of people with Down Syndrome are short stature, weak muscles, slanted eyes, a pushed-in nose bridge, and irregular mouths/tongues.
People with down syndrome has an extra chromosome in the 21st pair. The normal amount of chromosomes is 56 single chromosomes (23 pairs). A person with down syndrome has 57 chromosomes. Therefore, they look and act more different than people without the disorder. Instead of looking like their parents, people with down syndrome look more like other people who has down syndrome.
No, Fergie does not have Down syndrome!! She had ADHD when she was younger, though!!
Yes. A person with Marfan syndrome should have no problem flying in a commercial aircraft. Flights in an unpressurized aircraft are not recommended though, because the changes in altitude can cause a collapsed lung (pneumothorax), a particular risk for people with Marfan syndrome.
yes. Not every girl/woman has issues with heart, or a webbed neck, for example. The syndrome affects each woman differently though short stature and infertility are almost always present.
The exact cause of Tourette's syndrome is actually unknown. Studies have nailed down that genetic and environmental factors are involved when a person has this condition though.
No though DNA is in chromosomes DNA stands for Deoxyribonucleic acid and those acids are composed in DNA
