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.

DNA profiling is also used in DNA paternity testing to determine if someone is the biological parent or grandparent of a child with the probability of parentage is typically 99.99% when the alleged parent is biologically related to the child.
Example calculation of a paternity index. In paternity testing, Paternity Index (PI) is a calculated value generated for a single genetic marker or locus (chromosomal location or site of DNA sequence of interest) and is associated with the statistical strength or weight of that locus in favor of or against parentage given the phenotypes of the tested participants and the inheritance scenario.
DNA ligases that join broken DNA together had been discovered earlier in 1967, [36] and by combining the two technologies, it was possible to "cut and paste" DNA sequences and create recombinant DNA. Plasmids , discovered in 1952, [ 37 ] became important tools for transferring information between cells and replicating DNA sequences.

Haplogroup P also known as P-F5850 or K2b2 is a Y-chromosome DNA haplogroup in human genetics. P-F5850 is a branch of K2b (previously Haplogroup MPS; P331), which is a branch of Haplogroup K2 (K-M526). The haplogroup K2b splits into K2b1 (haplogroup MS*) and K2b2 (haplogroup P-F580, Y-DNA P*). Basal P* (P-PF5850*) is found in Southeast Asia.
Genome size ranges (in base pairs) of various life forms. Genome size is the total amount of DNA contained within one copy of a single complete genome.It is typically measured in terms of mass in picograms (trillionths or 10 −12 of a gram, abbreviated pg) or less frequently in daltons, or as the total number of nucleotide base pairs, usually in megabases (millions of base pairs, abbreviated ...
According to the 2020 census, the population of the Philippines is 109,033,245. [7] The first census in the Philippines was held in the year 1591 which counted 667,612 people. [8] The majority of Filipinos are lowland [broken anchor] Austronesians, [9] while the Aetas , as well as other highland groups form a minority.
