Which one of the following is NOT an application of genomics?
- Correct answerAIt is used in pedigree analysis of cats, dogs, horses and human.
- BIt is used in agriculture to develop transgenic crops with desirable characters.
- CIt can lead to the introduction of new genes in microbes to produce enzymes, biofuels etc.
- DGenetic markers developed in genomics have applications in forensic analysis.
Solution
Genomics is the comprehensive study of genomes, including their structure, function, evolution, and mapping. Its major applications include:
1. In agriculture, it is used to develop transgenic crops with desirable characters.
2. In biotechnology, it leads to the introduction of new genes in microbes to produce enzymes, therapeutic proteins, and biofuels.
3. In medicine and forensics, genetic markers developed through genomics are widely used for forensic analysis and disease diagnosis.
Pedigree analysis is a classical genetics tool used to trace the inheritance of specific traits or genetic disorders through multiple generations of a family based on observable phenotypes and family history. It relies on Mendelian principles rather than genomic sequencing or analysis. Therefore, pedigree analysis is not considered an application of genomics.
