Cytogenetics is a branch of genetics that is concerned with the study of the structure and function of the cell.

Molecular Cytogenetics

Molecular cytogenetics involves the combination of molecular biology and cytogenetics. In general this involves the use of a series of techniques referred to as fluorescence in situ hybridization, or FISH.

Molecular Genetics

Molecular genetics is the field of biology and genetics that studies the structure and function of genes at a molecular level.

Paternity and Parentage Testing

Parental testing is the use of genetic fingerprinting to determine whether two individuals have a biological parent–child relationship.


Pre-implantation genetic diagnosis (PGD) refers to genetic profiling of embryos prior to implantation.

Forensic Genetics

DNA profiling is used in parental testing and criminal investigation.
