how many chromosomes are shown karyotype?
33219
Human karyotype The normal human karyotypes contain 22 pairs of autosomal chromosomes and one pair of sex chromosomes (allosomes). Normal karyotypes for females contain two X chromosomes and are denoted 46,XX; males have both an X and a Y chromosome denoted 46,XY.

Humans have 46 chromosomes, so our diploid number is... a representation of the chromosomes found in a cell arranged according to a standard format.

Humans are diploid organisms, carrying two complete sets of chromosomes in their somatic cells: one set of 23 chromosomes from their father and one set of 23 chromosomes from their mother. The two sets combined provide a full complement of 46 chromosomes.

For example, most eukaryotes are diploid, like humans who have 22 different types of autosomes, each present as two homologous pairs, and two sex chromosomes. This gives 46 chromosomes in total.
632853
Most people have 46 chromosomes in each of their cells. People with Down syndrome have 47, and because of that they may look and learn differently.
1253394
Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 1, one copy inherited from each parent, form one of the pairs.
1167905
A human diploid cell has 46 chromosomes in 23 pairs.
1033054
A human's 46 chromosomes can be grouped into 23 pairs of chromosomes called... homologous chromosomes. similar in shape and size, and that the two chromosomes carry the same gene.
747996
The rule of karyotyping is to arrange 22 autosomes following the size and sex chromosomes, X and Y, at the end. Chromosomes are classified into seven groups, A to G, by the length and centromere position. Characteristics of each chromosome group will be explained below.

Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Results of a karyotype test are usually available within 1 to 2 weeks.
62759
Humans have an additional pair of sex chromosomes for a total of 46 chromosomes. The sex chromosomes are referred to as X and Y, and their combination determines a person's sex. Typically, human females have two X chromosomes while males possess an XY pairing.
738649
How many chromosomes do people have? In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females.
43616
For example, humans are diploid (2n) and have 46 chromosomes in their normal body cells. These 46 chromosomes are organized into 23 pairs: 22 pairs of autosomes and 1 pair of sex chromosomes.

The karyotype is the number , size and shape of chromosomes there are in a cell, it includes the autosome and the sex chromosomes. The number of chromosomes in a species is specific to that species . There fore the number of autosomes is also specific for that particular species.
868722
Karyotypes describe the chromosome count of an organism and what these chromosomes look like under a light microscope. Attention is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics.
45175
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.
