Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression , or through biochemical analysis to measure specific protein output.

A DNA microarray is a collection of microscopic DNA spots attached to a solid surface. Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome. When a gene is expressed in a cell, it generates messenger RNA (mRNA). Overexpressed genes generate more mRNA ...
A genealogical DNA test is a DNA-based genetic test used in genetic genealogy that looks at specific locations of a person's genome in order to find or verify ancestral genealogical relationships, or (with lower reliability) to estimate the ethnic mixture of an individual.
The use of DNA sequencing has also led to the development of new forensic techniques, such as DNA phenotyping, which allows investigators to predict an individual's physical characteristics based on their genetic data. In addition to its applications in forensic science, DNA sequencing has also been used in medical research and diagnosis.
Genetic genealogy – DNA testing to infer relationships; Haplotype – Group of genes from one parent; Meiosis – Cell division producing haploid gametes; Nucleic acid notation – Universal notation using the Roman characters A, C, G, and T to call the four DNA nucleotides; Nucleic acid sequence – Succession of nucleotides in a nucleic acid
The test also scanned for physical traits, like body size and coat color, but not personality traits like the others did. Where Basepaws shines, though, is its wealth of educational content.
