No, W and Z were just chosen as the names to distinguish them from X and Y.
They have 22 chromosome pairs or 44 chromosome and 2 sex cell. Here's a picture:
The question is not complete. You need more context than this. What chromosome is it? 21? 23? 5? it autosomal? cmon man i cant answer this
It depends which species you are. There is the XY system (which mammals use) where it is the presence of the Y chromosome that induces male development. The Y chromosome contains genes like Sry that initiate the male developmental program. Male mammals have an X and a Y chromosome, female mammals have two X chromosomes. However, for other species, like birds, use the so-called ZW sex chromosome system where it is actually the absence of the W chromosome that permits male development - male birds have two Z chromosomes and female birds have a W and a Z chromosome. And then there's the X0 system, which many insects use, where two copies of an X chromosome results in a female but a single copy of an X chromosome results in a male.
A metacentric chromosome has two equal arms because the centromere can be found in the median position. A telecontric chromosome, on the other hand, is like a straight rod. Its centromere is in the terminal position.
8 is the chromosome number, q means the long arm of the chromosome, and the 24 is the position on the long arm. It's like coordinates to find the position on the chromosome.

The chromosome's role is to tell the stem cells what to make and how to look like. For example, if you have brown eyes, and the genetic code is 01001, then that is what the chromosome tells the cell to look like and function like.

No. People with Klinefelter's syndrome have a normal Y chromosome and 2 normal X chromosomes.

then you know what your looking at and for
They are the same size and shape (identical)
The trisomy 21 in a karyotype would look like extra chromosome 21 I ^^
W. Waldeyer coined the term chromosome (1888)
wertyuiop
It doesn't, it looks like a "W".
