Question
Analyze the karyotype shown. Indicate if it is a chromosomal male or achromosomal female. If the karyotype is normal, write the word normal under name or description. If the karyotype is abnormal, name or describethe disorder.

Transcribed Image Text:### Human Karyotype Analysis
The image presents a human karyotype, which is an organized profile of a person's chromosomes. Chromosomes are paired and arranged by size and banding pattern, which is visible after being stained. This karyotype features 22 pairs of autosomes, numbered from 1 to 22, as well as the sex chromosomes X and Y.
**Features of the Karyotype:**
- **Chromosome Pairs 1-22:** These are autosomes, which are chromosomes not involved in determining the sex of an individual. Each pair is made up of two homologous chromosomes, one inherited from each parent.
- **Sex Chromosomes (X and Y):** This karyotype includes one X and one Y chromosome, indicating a male individual. In females, there would be two X chromosomes.
**Significance:**
This karyotype can be used to identify genetic disorders arising from abnormal chromosome numbers, such as Down syndrome (trisomy 21) or Turner syndrome (monosomy X). It is a critical tool in genetics for studying chromosomal abnormalities and inheritance patterns.
