Autosomes
The chromosome of a bacterium does essentially the same thing that chromosomes do for all life forms. It describes the formation of proteins for the organism, allowing it to produce and grow the proper structures at the proper time, allowing it to survive most efficiently.
An extra chromosome can cause genetic disorders such as Down syndrome, which is caused by an extra copy of chromosome 21. This leads to developmental delays, intellectual disabilities, and certain physical characteristics.
The word "chromosome" comes from the Greek words "chroma", meaning color, and "soma", meaning body, referring to the colored bodies seen in cells during cell division when chromosomes are most condensed and visible.
nucleus → chromosome → gene
genome -> chromosome -> DNA -> gene
Most have 2. Some have 3 :-(
Most homologous pairs look alike. They carry genes for the same characteristics and line up on the chromosome in the same order!

The most useful characteristics for matching homologous pairs of chromosomes are size, centromere position, and pattern of banding. Size refers to the length of the chromosome, centromere position is the location of the centromere on the chromosome, and banding patterns are unique patterns of light and dark bands that can be used to identify specific regions on the chromosome.
Many sex-linked genes are found on the X chromosome. More than 100 sex-linked genetic disorders have now been mapped to the X chromosome. The human Y chromosome is much smaller than the X chromosome and appears to contain only few genes.
Yes, not all genes located on the X chromosome control female sexual characteristics. The SRY gene on the Y chromosome is responsible for male sexual development. However, genes on the X chromosome like the XIST gene are involved in the regulation of X chromosome inactivation, a process critical for normal development in females.

The topic itself will dictate where the most leverage should occur.
If you mean haploid, as in half of each chromosome, or containing only one chromatid from each full chromosome, thenthe cell is called haploid.
