Is turner syndrome caused by a mutation?
No, it is caused by Nondisjunction. That means the chromosomes didn't separated properly.

Is cancer a genetic disease?
No. It is caused when a normal cell devides into a mutated cell, which then, if conditions are right, devide constantly and rapidly.
What does nondisjunction lead to?
Various kinds of genetic disorders, as the embryo will end up with two copies or zero copies of a gene.
What is the difference between translocation and nondisjunction?
Nondisjunction is when a Chromosome is unable to separate correctly during cell devision. Translocation (In Chromosomes) is when an abnormality is caused by the rearrangement of parts between non-homologous Chromosomes.
What is the cause of the Down syndrome disorder?
There are many causes for Down Syndrome. One of the cause is: Nondisjunction : The body's cells contains nucleus which has 23 pairs of chromosomes; the nucleus is storage for genetic material (genes). The occurence of Nondisjunction is mainly caused by an error in cell division and an embryo ends up with three copies of chromosome 21 instead of two. In conception the 21st chromosome in a sperm or egg can have an abnormal cell… Read More
What is the difference between crossing over and nondisjunction?
Nondisjunction is the failure of chromosomes to separate properly during cell division (both mitosis and meiosis). Crossing over, on the other hand, is the exchange of genetic material between homologous chromosomes during meiosis.
Chromosomal disorders such a Down syndrome Klinefelter's syndrome and turner's syndrome are caused by?
Nondisjunction during meiosis.
Does stress cause eczema or skin conditions?
Eczema is genetic, as are some other skin conditions. Others, such as ringworm, can be caused by fungus. Stress can make the symptoms worse, but is not typically believed to be a cause.
What causes dwarfism in humans?
Human dwarfism is usually the results of a combination of genetic factors and endocrine malfunction. It can also be caused by conditions such as kidney disease.
Does nondisjuction occur in mitosis or meiosis?
nondisjunction occurs in meiosis, this is when the chromosomes do not separate during anaphase and it causes some genetic disorder like trisomy
What Type of abnormalities can a karyotype show?
A karyotype can show any abnormality on the genetic level, including inherited syndromes, mutated genes inside the chromosome, and nondisjunction of the chromosomes.
What are the possible causes of Down's syndrome?
When a baby is conceived, it receives genetic information from its parents in the form of 46 chromosomes: 23 from the mother and 23 from the father. In most cases with Down syndrome, the child receives an extra copy of Chromosome 21 - for a total of 47 chromosomes instead of 46. It's this extra genetic material that causes the physical features and developmental delays associated with Down Syndrome. This form of Down syndrome is… Read More
Most human genetic disorders are caused by the expression of?
Genetic Disorders are caused By a change in a person's DNA. Recessive alleles is the most human genetic disorder.
How does crossing over and nondisjunction contribute to variation and increase genetic diversity in a population?
Crossing over is when two homologous chromosomes switch genes. This causes them to become different. Nondisjunction is when there is an incorrect splitting of a chromosome. These two types of variation result in a different set of genes each time an egg and a sperm collide by chance,
Genetic disorders are caused by what?
Genetic disorders are caused by mutations that happen in a person's DNA. There are a number of reasons why this happens.
Genetic disorders are caused by?
Genetic disorders are caused by abnormalities in the genome. These disorders are rare and may or may not be hereditary.
What genetic disorders are caused by polygenic inheritance?
Hip Dysplasia in dogs is a genetic disorder caused by polygenic inheritance.
What is nondisjunction and what happens when it occurs?
What will happen if nondisjunction occurs?
What causes people to be double jointed?
Being double jointed can be caused by genetic syndromes, chromosomal disorders and certain medical conditions. Or it may be a genetic trait unrelated to anything else. Two main genetic syndromes are hypermobility syndrome and Marfan syndrome. Chromosomal Downs and Fragile X. The term hypermobility is the medterm.
Which process could result in the type of cell mutation that causes Down syndrome?
Down's syndrome is caused by trisomy of the 21st chromosome. This is mostly caused when the chromosome pair fails to separate properly (nondisjunction).
Many genetic disorders of humans are caused by?
Genetic disorders are commonly passed down or caused by mutations. In humans mutations can be caused by errors in mitosis or by mutagenic agents.
Is Down syndrome caused by a chromosome mutation or a gene mutation?
Down syndrome is caused by the presence of an extra 21st chromosome. Instead of the typical 2 copies, a person with DS will have 3 copies (known as a trisomy). Down syndrome is not a mutation, but is usually an inherited condition due to the extra genetic material in one of the parents' egg or sperm, whether by Nondisjunction or by Translocation. Mosaic is a rare form of DS wherein after conception with typical genetic… Read More
What disease is called by a genetic mutation?
There are many diseases caused by genetic mutations, particularly syndromes such as Down's which is caused by a mutation to the 21st chromosome.
What Causes genetic disorders?
Genetic disorders are caused by either changes in the DNA of genes. Or caused by changes in the overall structure or number of chromosomes.
Change in phenotype of bacteria caused by the presence of foreign genetic material?
change in phenotype of bacteria caused by the presece of foreign genetic material
What metaphase does nondisjunction occur in Metaphase 1 or metaphase 2?
Non-disjunction is the failure of a pair of chromosomes or chromatids to separate. Since this happens in both metaphase I and II, non-disjunction can occur in either stage. In metaphase I it is the failure of the two homologous chromosomes in the pair to separate. In this case all of the gametes will be affected. In metaphase II it is the failure of the two sister chromatids to separate. In this case only half of… Read More
