When a chromosome is abnormal, it can cause health problems in the body. Each chromosome arm is divided into regions, or cytogenetic bands, that can be seen using a microscope and special stains. The Y chromosome is one of two sex chromosomes in therian mammals, including humans, and many other animals.The other is the X chromosome.Y is normally the sex-determining chromosome in many species, since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproduction.In mammals, the Y chromosome contains the gene SRY, which ⦠Aneuploidy can be full, involving a whole chromosome missing or added, or partial, where only part of a chromosome is missing or added.

Chromosome mutations can affect both homologous and non-homologous chromosomes. So while the chromatin is a lower order of DNA organization, chromosomes are the higher order of DNA organization. Diploid definition is - having two haploid sets of homologous chromosomes. Period. Chromosome mutation: Change or alteration into the structure or number of chromosomes is known as chromosomal mutation.

Definition: Each human chromosome has a short arm ("p" for "petit") and long arm ("q" for "queue"), separated by a centromere. The most common type of chromosomal abnormality is known as aneuploidy, an abnormal chromosome number due to an extra or missing chromosome.Most people with aneuploidy have trisomy (three copies of a chromosome) instead of monosomy (single copy of a chromosome). In most sexually reproducing organisms, somatic cells are diploid, containing two copies of each chromosome, while the sex cells are haploid, having one copy of each chromosome.
