In humans if a non-disjunction event led to an individual with a genotype of XO they would?
In humans, a non-disjunction event leading to a genotype of XO results in Turner syndrome. Individuals with Turner syndrome are typically female and may exhibit symptoms such as short stature, lack of ovarian development, and various physical abnormalities. They often have a normal intellectual capacity but may face challenges in fertility and certain health issues. Overall, Turner syndrome is a chromosomal condition that affects physical development.

What kind of mutation occurred to produce a person with the genotype XXY?
The genotype XXY is associated with Klinefelter syndrome, which arises from a nondisjunction event during meiosis. This mutation results in the failure of homologous chromosomes or sister chromatids to separate properly, leading to an extra X chromosome in males. Consequently, individuals with XXY typically exhibit male characteristics but may experience various physical and developmental differences.
What is a meiotic nondisjunction event?
Nondisjunction is when homologous chromosomes fail to separate in Meiosis I, or sister chromatids fail to separate in Meiosis II or Mitosis. This results in daughter cells with an incorrect number of chromosomes.
Which best describes probability A. The genotype ratio for a certain trait B. The likelihood that something will happen C. The most likely possible outcome D. The number of offspring with a trait?
b the likelihood of an event occurring apex
Since it is possible to have identical twins of different genders could there be a nondisjunction in the sex chromosomes causing one twin to have Turners syndrome and the other to have Kleinfelters?
No, it is not possible for identical twins to have different sex chromosome conditions like Turner syndrome and Klinefelter syndrome. Identical twins develop from a single fertilized egg, so they have the same genetic material, including the sex chromosomes. If there was a nondisjunction event in one twin leading to an abnormal number of sex chromosomes, it would affect both twins, not just one.
What is an observable fact event of circumstances?
An observable fact is something that can be seen, heard, or experienced directly by an individual or through scientific measurement. An event is a specific occurrence or happening that can be identified at a particular time and place. Circumstances refer to the conditions or factors surrounding a situation or event.
What is the genetic event that results in Turner syndrome XO?
nondisjunction
What usual meiotic event leads to down syndrome In which parent?
Nondisjunction.
Is achondroplasia nondisjunction?
No, achondroplasia is not caused by nondisjunction. Achondroplasia is a genetic disorder caused by a spontaneous mutation in a gene involved in bone growth. Nondisjunction is a genetic event that occurs during cell division and can lead to abnormal chromosome numbers in offspring.

Nondisjunction is when homologous chromosomes fail to separate in Meiosis I, or sister chromatids fail to separate in Meiosis II or Mitosis. This results in daughter cells with an incorrect number of chromosomes.
How can nondisjunction in meiosis result in a diploid gamete?
If all of the chromosomes fail to separate in meiosis, then nondisjunction can result in a diploid gamete. This is a type of chromosomal mutation. In animals, a zygote produced from the union of a mutated diploid gamete and a normal haploid gamete will have triploidy, which is lethal. In plants, this is not necessarily lethal.
Is archery an individual event?
Archery can be both a team, and an idividual event.
What is an evolutionary event in which population size is radically reduced?
Selection of a particular genotype threatened by hostile environment can radically reduce the population size of an organism.
Is klinefelter's syndrome an inheritance?
It is a condition in which human males have an extra X chromosome. It is inherited when the extra X chromosome is retained because of a nondisjunction event during meiosis I (gametogenesis).
Is relay a team or individual event?
TEAM
Is bowling an individual sporting event?
yes :)
What is the number of repetitions of an event?
The number of repetitions of an event depends on the type of event and its individual structure, which can range from 2 to 10.
