Turner Syndrome
Turner Syndrome
The XO condition is known as Turner's Syndrome.
X chromosome only
What differentiates a male from a female based off the chromosomes that are present is that a male organism will have X and Y chromosomes whereas a female organism will have X and X chromosomes.
The female fetus has a Y chromosome while the fetus only has two x chromosome.
Its not a guarantee, but generally it holds true. There are some instances when the part of the y chromosome which determines sex is tacked onto an X chromosome. This can result in XX males. In general though the Y chromosome is responsible for making a biological male.
They could be female ;)
A female with a gene for a genetic disorder will usually only have it on one of her two X chromosomes. The other chromosome will carry the healthy version of the gene, which will carry out that gene's function when the other chromosome cannot. Males will exhibit the disease if they have the gene as a male human only has one X chromosome. So, in order for a female to have a genetic disorder carried on her sex chromosome her mother would have to have the defective gene and her father would have the disorder.
X Chromosome results in a female Y Chromosome results in a male All sperm are either going to be an X or Y chromosome All eggs are X chromosome only
The human male has both an X and Y chromosome which determines the sex of an offspring. Female only have the X chromosome.
The female can only pass on ONE "X". an XX female offspring must get the second X from the father.
In males, sperm contain only one sex chromosome. In females, eggs contain only one sex chromosome.
