| 释义 | karyotype noun[ C ] biology specializeduk /ˈkær.i.əʊ.taɪp/ us /ˈker.i.oʊ.taɪp/ the complete set of chromosomes(= the rod-like structures found in all living cells, containing the chemical patterns that control what an animal or plant is like) of a person or animal, or an image of them produced from a single cell and arranged in order: The karyotype was reported as normal. Two distinct size groups of chromosomes are revealed in the karyotype. a test done to produce an image of the complete set of chromosomes of a person or animal, used to see if the number or structure of chromosomes is normal: A karyotype may be done if a chromosomal disorder is suspected. The test is a full karyotype that looks at all of the baby's chromosomes in detail.

The fetal karyotype revealed an apparently balanced chromosomal translocation. The clinical services include genetic counseling, biochemical testing, ultrasound examination, karyotype testing, and molecular genetics testing. Because these rearrangements change chromosome size, shape and number, their study may provide important clues to the evolution of karyotypes. A fetal karyotype will identify underlying chromosome abnormalities. Because of the advanced nature of the pregnancy, a karyotype was not performed. However, the identification of all chromosomal aberrations in a complex karyotype was often not possible from such patterns. All three cases had abnormal karyotypes and the latter case had nuchal oedema. Individuals were assigned to one of seven groups according to karyotype. These characters were polarized by the outgroup which consisted of the 2n=40 all-acrocentric karyotype. But the existence of generalized karyotypes usually does not exclude identification of species by karyotypic characters. However, the evolutionary significance of karyotype variation was never explored, mostly due to the absence of an underlying theoretical model. Low-grade cases are those with less than 5% bone marrow blasts, together with a cytopenia of one lineage and a normal karyotype. A first insight in karyotype evolution can be gained by analysis of chromosome size polymorphism. Two distinct size groups of chromosomes are revealed in the karyotype.
