Genotypingové

Genotyping is the process of determining the specific genetic makeup of an individual organism. This involves identifying variations at the DNA level, often referred to as genetic markers or polymorphisms. These variations can occur as single nucleotide polymorphisms (SNPs), insertions, deletions, or larger structural changes within the genome. Genotyping is a fundamental technique in molecular biology and genetics, with applications spanning a wide range of fields.

The primary goal of genotyping is to understand the genetic differences between individuals. This information is crucial for various purposes, including identifying genetic predispositions to diseases, tracking the inheritance of traits, and understanding evolutionary relationships. In agriculture, genotyping is used to select for desirable traits in crops and livestock, such as disease resistance or yield. In forensics, it plays a vital role in identifying individuals from biological samples.

Several technologies are employed for genotyping, each with its own advantages and limitations. These include DNA sequencing, microarrays, and PCR-based methods. DNA sequencing, particularly next-generation sequencing (NGS), provides a comprehensive view of the entire genome, allowing for the detection of a vast number of variations. Microarrays utilize immobilized DNA probes to detect specific known variations. PCR-based methods, such as allele-specific PCR or fragment length polymorphism analysis, are often used to genotype specific known markers. The choice of genotyping method depends on the specific research question, the desired resolution, and the available resources.
