A karyotype refers to a full set of chromosomes from an individual that can be compared to a normal karyotype for the species via genetic testing. A chromosome anomaly may be detected or confirmed in this manner. Chromosome anomalies usually occur when there is an error in cell division following meiosis or mitosis.
When a chromosome deletion occurs, part of a chromosome is removed, or deleted. Most of the time, the chromosomes can be found as long thin strands of DNA in the nucleus. They are all wound round each other, so there are plenty of opportunities for interactions with other chromosomes and with themselves.hromosome mutations are due to changes in the structure of a chromosome, as opposed to gene mutations, which are changes within the chemical makeup of a chromosome. Chromosome mutations can actually be detected by looking at the DNA through a microscope.
