Turner Syndrome is a chromosome mutation. It is where some of the X's in the cell either doesn't form right or breaks off and to help repair itself it forms into an O shape.
Disorders, such as Down's Syndrome, are caused by nondisjunction.
No " following, but a condition such as trisomy 21, Downs syndrome, is caused by nondisjuction. The chromosomes fail to separate properly and one child is left with an extra chromosome number 21. The potetial other children that could have been born of this nondijuction event, those with only one chromosome 21, are not viable.
No, only the gametes would be indicative of sterility. It is possible that the individual (though incredibly rare) to have "chimera" syndrome, where two non-identical twins merge to form one fetus. Turner's Syndrome is the absence of the male sex chromosome BTW. That chromosome carries little genetic information, and is possible during mitosis to "loose" it, but still create a mostly viable cell.
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.
One disorder could be colorblindness. Colorblindness is most common in males because in order to have to disorder you must carry two mutated X chromosomes. Another recessive genetic disorder you can get is called Hemophilia. This is a disorder in which the genes for hemoglobin are not present and your body is not able to create blood clots and a simple scratch can be very serious.
Girls born with Turner's syndrome are born with only one x chromosome instead of the average two x chromosomes. Mood swings are apparent in all females, however, a chromosomal disorder such as Turner's syndrome can cause one's emotions and chemical make-up to be a little out of whack and this causes more frequent, intense mood swings. This could also be linked to a personality disorder as well, not just the fact that people with Turner's syndrome are missing their second x chromosome.
Disorders, such as Down's Syndrome, are caused by nondisjunction.
You could try some info about DNA/RNA/protein synthesis or genetic disorders such as Edward's or Turner's syndrome.
Chromosomal disjunction during meiosis leaving one of the gametes that meet in random fertilization short an X chromosome is the simplest fertilization mishap that results in Turner's syndrome. One X chromosome.
Could someone explain to me how a widget works, please?
