Karyotype
Karyogram of human female
A karyotype is the complete set of all chromosomes of a cell of any living organism. The chromosomes are arranged and displayed (often on a photo) in a standard format: in pairs, ordered by size.
Karyotype of a Normal Human Male
To prepare this display, a photograph of metaphase chromosomes (dyads) was cut into pieces and the individual images assembled in homologous pairs.
Karyotype
A karyotype is an individual's collection of chromosomes. The term also refers to a laboratory technique that produces an image of an individual's chromosomes.
Female Karyotype
Normal female karyotype, with two large X chromosomes.

KARYOTYPE OF TRISOMY 21 FEMALE
The rate of non disjunction is correlated with maternal age. The probability of a woman having a fetus with a chromosome defect increases with age.
Male intersexuals (karyotype 46XY) (also called male pseudohermaphrodites) have normal testes with female or ambiguous genitalia. They most often result from several different genetic alterations in pathways of testosterone synthesis and metabolism.

X and Y chromosomes in organisms that determine the sex of an individual. In human beings females have two X chromosomes in diploid cells; males have an X and a Y chromosome. The sex chromosomes comprise the 23rd chromosome pair in a human karyotype.
They also found statistically significant premating isolation between the WH population and the field populations. Finally, the Woods Hole population showed slightly different karyotypes from the field populations.
The sex chromosomes comprise the 23rd chromosome pair in a karyotype. Compare autosome.
Single-gene disorder Hereditary disorder caused by a mutant allele of a single gene (e.g., Duchenne muscular dystrophy, retinoblastoma, sickle cell disease).
Karyotype -- a set of photographed, banded chromosomes arranged in order from largest to smallest. Lligase -- an enzyme that functions in DNA repair.
