Who are lacking an X chromosome are designated XO?
Females
A female with only one x chromosome is called?
The XO condition is known as Turner's Syndrome.
Describe how the karyotype of an XXY human would differ from that of an XO human?
The karyotype of an XO human would be deficient one X chromosome, compared to that of a normal female, and it would result in a female. Normal human females only use one X chromosome, whereby one is inactivated, which is why an XO human is viable. An XXY human would have one extra X chromosome as compared to that of a normal male, and it would result in a male. Again, an X chromosome is inactivated, which is why an XXY human is viable. XO is referred to as Turner Syndrome. XXY is referred to as Klinefelter Syndrome.
Why is karyotype called 45xo?
This particular karyotype has 45 chromosomes (instead of the usual 46). "XO" tells us that the karyotype is missing a sex chromosome: the individual has an X, but no homologous sex chromosome (X or Y) to complete the diploid pair.
How sex is determined in Valanga Sp with regard to its chromosome?
Valanga sp. sex is determined by using the XO system. This system use only one type of sex chromosome, the X. Females are XX while males have only one sex chromosome (XO). Sex of the offspring is determined by whether the sperm cell contain and X chromosome or no sex chromosome.
Which type of fertilization could result in Turner 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.
Which genetic disease is it when someone only has a y chromosome but no x chromosome?
That isn't physically possible. All XO individuals are females with Turner's syndrome. Individuals with only a Y chromosome do not survive.
The genotype xo results from what?
The genotype XO results from the absence of a second sex chromosome in an individual. This condition is known as Turner syndrome and is characterized by a single X chromosome in females instead of the usual two. It can lead to various developmental and physical abnormalities.
Which syndrome is characterized by the XO chromosome abnormality?
Turner syndrome is characterized by an XO chromosome abnormality, where individuals have only one X chromosome instead of the usual two. This condition can lead to various physical and developmental abnormalities, such as short stature, heart defects, and infertility. Treatment may involve hormone therapy and fertility treatment.
Which combination of sex chromosomes results in Turner syndrome?
Turner syndrome is typically caused by the presence of a single X chromosome in an individual, leading to a 45,X karyotype, where one of the sex chromosomes is missing or incomplete. This condition is more commonly seen in females.
A karyotype of a human female shows that she has only one sex chromosome what is the genotype for her condition?
The genotype for this condition is Turner syndrome, which is characterized by a single X chromosome (usually denoted as 45,X). This results in a female individual with certain physical characteristics and potential health complications.
What are the correct designation of the paired sex chromosomes?
the male chromosome is XY the female chromosome is XX
