Translocation. On Chromosome 20.
The most common type of chromosomal disorder is the Down syndrome caused by an added copy of chromosomes 21. More common chromosomal disorders are Klinefelter's syndrome and Turnerâ??s syndrome.
Chromosomal abnormalities can result from either a variation in the chromosome number or from structural changes. These events may occur spontaneously or can be induced by environmental agents such as chemicals, radiation, and t. However, mutations are most likely due to mistakes that occur when the genes are copied as the cells are dividing to produce new cells. These abnormalities may involve the autosomes, sex chromosomes, or both. The disruption of the DNA sequence or an excess or of the genes carried on the affected chromosomes results in a. Such a change may or may not alter the protein coded by a gene. Often, however, a mutation results in the disruption of gene functionality. The resulting altered or missing protein can the way a gene is meant to function and can lead to clinical disease. Only mutations occurring to the DNA in the gametes will potentially pass on to the offspring.Mutations appear in gametes in one of two ways. A mutation may be inherited from one of an individual's parents. However, a mutation may also occur for the first time in a single, or during the process of fertilization between an egg cell and a. In this case the mutation or change is often called a de novo mutation. The parents are not affected by the condition and are not "carriers" of the mutation. The affected individual will have this mutation in all of his or her cells and may be able to pass the mutation on to any offspring.
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.
structural mutation have four types of change in the chromosomal structure: TRANSLOCATION, INVERSION, DELETION AND DUPLICATION.while:numerical mutation results from nondisjunction, or the failure of a pair of homologous choromosomes or a pair of sister chromatids to separate during meiosis or mitosis. The effect of nondisjunction during mitosis is not harmful as the effect of nondisjunction during meiosis.
Asexual reproduction results in identical offspring unless a mutation occurs. Mutation is a process wherein the genetic material of an organism is altered.
translocation
Cri du Chat Syndrome or Chromosome 5p- is a chromosomal condition that results in brain abnormalities.
The most common type of chromosomal disorder is the Down syndrome caused by an added copy of chromosomes 21. More common chromosomal disorders are Klinefelter's syndrome and Turnerâ??s syndrome.
It's either a mutation with the gene, or either the mother or father donates an extra chromosome. 2nd Answer: True, and Down Syndrome is not a genetic disease and has nothing to do with family history. By the way, the kind of chromosomal mistake that causes Down Syndrome occurs in many people, but on different chromosomes. Mostly, your body is so tolerant of this kind of mistake that you never see any results.
when parts of chromosomes are broken off and lost during mitosis the results is a chromosomal mutation

A deleterious mutation.
Yes, a point mutation will cause the cell to make an incompelete polypeptide chain that is non-functional, if the mutation results in a stop codon. This type of a mutation is also called as the Nonsense Mutation.
