Numeric abnormalities
– not a multiple of the haploid number

aneuploidy

2

ex of aneuploidy

ex. Trisomy, monosomy

3

– chromosome number higher than 46

polyploidy

4

ex of polyploidy

ex. Triploidy (3n), tetraploidy(4n) ,hypodiploid, hyperdiploid, high hyperdiploid

5


occurs after rearrangement of chromosomes

Structural Abnormalities

6

: portion of the chromosome is missing or deleted.


Deletions

7

Duplications:

portion of the chromosome is duplicated, resulting in extra genetic material.

8

In a _____, segments from two different chromosomes have been exchanged.

reciprocal translocation

9

A portion of the chromosome has broken off, turned upside down and reattached, therefore the genetic material is ..

Inversions:

10

Formed by the mirror image copy of a chromosome segment including the centromere.

Isochromosome:

11

A portion of a chromosome has broken off and formed a circle or ring.

Rings:

12

This can happen with or without loss of genetic material.

Rings:

13

technology that is used to analyse the physical and chemical characteristics of particles in a fluid as it passes through at least one laser.

flow cytometry

14

Cell components are fluorescently labelled and then excited by the laser to emit light at varying wavelengths.
