Deletion of centromere, results in an acentric chromosome; Duplication - mutation in which a section of DNA is duplicated and both copies end up in the same chromosomes. Can occur because of an error during the duplication process of form an error during meiosis Inversion- mutation in which a section of DNA is put in backwards. Translocation : in which two non-homologous chromosomes exchange sections of DNA Aneuploidy: when one or more chromosomes are either lost or added to the normal set of chromosomes. Result of non-disjunction, either mitotic or meiotic Polyploidy : 3 or more sets of chromosomes (can reproduce sexually and axesually ) Haploidy: Usually lethal because of the presence of recessive lethal mutations that will act as dominant characteristics in the haploid state Monoploidy : only one set of chromosomes Diploidy : Normal: 2 sets of chromosomes What is cytogenetics and how is it performed?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
