They have 22 chromosome pairs or 44 chromosome and 2 sex cell.
Here's a picture:

Achondroplasia is caused by a mutation in the FGFR3 gene and is not related to a specific karyotype. It is inherited in an autosomal dominant pattern, and individuals with achondroplasia typically have a normal karyotype (46 chromosomes in humans).
what is the 2n chromosome number for a normal bug
A normal female karyotype would be described as 46 XX. A karotype shows the pairs of metaphase chromosomes of an individual cell and sorted according to size.
I believe the answer to your question is 23.
The trisomy 21 in a karyotype would look like extra chromosome 21 I ^^

There are 46 chromosomes in a human Karyotype.
A normal karyotype will show all 23 chromosomes at normal growth, and the end will show an either XY (boy) or XX (girl). Karyotypes of people with autosomal diseases and other diseases associated with chromosomes will show abnormalities on that certain chromosome. For example, Down syndrome is caused by a whole extra chromosome on chromosome 21. This extra chromosome can be seen on the karyotype.

Yes. A karyotype will show the chromosomes and an affected person will have XXY instead of XY for a normal male.

A karyotype tells you if you have the normal ammont of chromosomes (46 for humans), it can also tell you if you have more or less and if this is the case what it is that you have. The most common syndrome would be Down Syndrome, or trisomy 21. Down Syndrome is also called trisomy 21 because if you look at a karyotype from someone that has this syndrome then they have three coppies of the 21st chromosome.
A normal female karyotype would be described as 46 XX. A karotype shows the pairs of metaphase chromosomes of an individual cell and sorted according to size.
The pair of sex chromosomes (X and Y) is not homologous in a normal male karyotype. Males have one X and one Y chromosome, while females have two X chromosomes.
