karyotype

 [kar´e-o-tīp]
the chromosomal constitution of the cell nucleus; by extension, the photomicrograph of chromosomes arranged. See also illustration at chromosome.
Preparation of a karyotype. From Mueller and Young, 2001.

kar·y·o·type

(kar'ē-ō-tīp),
The chromosome characteristics of an individual cell or of a cell line arranged in descending order of size and according to the position of the centromere. Usually presented as a systematized array of metaphase chromosomes from a photomicrograph of a single cell nucleus.
Synonym(s): idiogram (1) , karyogram

karyotype

(kăr′ē-ə-tīp′)
n.
1. The characterization of the chromosomal complement of an individual or a species, including number, form, and size of the chromosomes.
2. A photomicrograph of chromosomes arranged according to a standard classification.
tr.v. karyo·typed, karyo·typing, karyo·types
To classify and array (the chromosome complement of an organism or a species) according to the arrangement, number, size, shape, or other characteristics of the chromosomes.

kar·y·o·type

(kar'ē-ō-tīp)
The chromosome characteristics of an individual cell or of a cell line, usually presented as a systematized array of metaphase chromosomes from a photomicrograph of a single cell nucleus arranged in pairs in descending order of size and according to the position of the centromere.

karyotype

1. The individual chromosomal complement of a person or species. The genome.
2. The CHROMOSOMES of an individual set out in a standard pattern and obtained from a photomicrograph taken in METAPHASE that has been edited with software so that the separate chromosomes are arranged in numerical order. This is done for the diagnosis of chromosomal disorders, as in prenatal detection of fetal abnormality.

karyotype

the CHROMOSOME complement of a cell or organism, characterized by the number, size and configuration of the chromosomes as seen during metaphase of MITOSIS.

Karyotype

A standard arrangement of photographic or computer-generated images of chromosome pairs from a cell in ascending numerical order, from largest to smallest.

Genetic analysis among karyotyped and nonkaryotyped individuals
The first group corresponds to the two karyotyped specimens identified as Oligoryzomys flavescens, and the second one represents the other individuals, including those karyotyped defined as Oligoryzomys nigripes, a clear grouping between the members of this group not occurring with regard to the collecting area.
These plants were each karyotyped from two well spread cells and it was noted that aneuploidy was due to an extra or missing SAT chromosome.
To date, eight blastocysts fully karyotyped as normal by CGH have been transferred to six patients with multiple recurrent IVF failures.
cyaneotaeniatus agree with that described for the chromosomes of the majority of pholcid species karyotyped thus far, except for acrocentric X chromosomes of Pholcus crypticolens Bosenberg & Strand 1906 (Suzuki 1954) and autosomes of Pholcus manueli Gertsch 1937 (under Pholcus affinis Schenkel 1953) (Xiuzhen et al.

Less than 10% of the world's species of birds have been karyotyped, of which very few have been passerines (Takagi & Sasak 1974; Tegelstrom & Ryttman 1981; Shields 1983; 1985; De Boer 1984).
Shields (1980) reported that 70% of all birds karyotyped have diploid numbers between 76 and 84.
