Which chromosomal abnormality is associated with part of a chromosome breaking away and attaching to a non-homologous chromosome?
The chromosomal abnormality associated with a part of a chromosome breaking away and attaching to a non-homologous chromosome is called a translocation. This can lead to various genetic disorders and cancers, such as chronic myelogenous leukemia (CML), where a piece of chromosome 9 and chromosome 22 exchange places, forming the Philadelphia chromosome. Translocations can disrupt gene function and regulation, potentially resulting in significant health issues.
What is mirroring chromosomes?
Mirroring chromosomes are a genetic abnormality. This abnormality is caused by an exact duplication of a chromosome segment, including the centromere.
Autosomal abnormality resulting in three copies of chromosome 21 is known as?
Trisomey-21
If Rett syndrome is a chromosomal abnormality what is the abnormality?
Rett syndrome is not primarily caused by a chromosomal abnormality, but rather a genetic mutation in the MECP2 gene located on the X chromosome. This gene provides instructions for making a protein that is important for brain development. Mutations in the MECP2 gene disrupt the production of this protein, leading to the characteristic features of Rett syndrome.
What chromosome is the sex determining chromosome?
That would be the chromosome number 23. Regarding the [sex] chromosome number 23, the female gametes always have a [haploid] X chromatid, whereas the male gametes are just as likely to possess a [haploid] X chromatid as they are to possess a [haploid] Y chromatid.
A organ that is effected by the Philadelphia chromosome?
The Philadelphia chromosome typically affects white blood cells, specifically the myeloid cells in the bone marrow. This abnormality is associated with chronic myeloid leukemia (CML), a type of blood cancer.
What is an example of a birth defect in which there is abnormality in the chromosome structure?
Down's Syndrome is an example of a birth defect characterized by an abnormality of the chromosome structure.
The chromosome abnormality that occuswhen part of one chromosome breaks off and is add to a different chromosome is?
Translocation
A person with Down syndrome has what type of chromosome abnormality?
Is caused by an extra number 21 chromosome.
What sex chromosomes do males possess?
Males possess one X chromosome and one Y chromosome.
What is mirroring chromosomes?
Mirroring chromosomes are a genetic abnormality. This abnormality is caused by an exact duplication of a chromosome segment, including the centromere.
Is achondroplasia a chromosomal abnormality?
Yes, it takes place in chromosome 4.
Is chromosomal abnormality in albinism?
yes it is. It affects chromosome 11.
Autosomal abnormality resulting in three copies of chromosome 21 is known as?
Trisomey-21
What is the disorder caused by having an abnormality on chromosome 21?
Down's Syndrome or trisomy 21.
Suppose your looking through a microscope and you see an exchange of chromosome segments between chromosome pair 7 and chromosome pair 15?
An exchange of chromosome segments is called a translocation. In genetics, it refers to a chromosome abnormality caused by rearrangement of parts between nonhomologous chromosomes.
What is the meaning of uniparental disomy?
Uniparental disomy is a chromosome abnormality where a pair of chromosomes only have DNA from one parent and are miss DNA from the other parent. This abnormality happens during mitosis.
