Forensic genetic detectives of Hyderabad crack Tamil Nadu monitor lizard case


The CCMB researchers said that forensic genetic evidence is a powerful tool to secure convictions in wildlife crimes.

The forensic genetic detectives of Hyderabad have uncovered a wildlife crime involving the mystery of occult and how the gullible can be taken for a ride by poachers. The DNA investigators in Hyderabad received small pieces of plant material for analysis. It turned out that the plant materials were, in reality, the gonads of male Bengal monitor lizard, which was killed by the poachers in Tamil Nadu.

Published as a case study in Springer Nature (September, 2024), the group of researchers from Hyderabad-based Centre for Cellular and Molecular Biology (CCMB), through their DNA analysis, helped investigators from Tamil Nadu to unravel the mystery and prosecute the poachers.

The poachers harvested the forked penises of monitor lizards and fraudulently sold them to individuals as the roots of a very rare plant Martynia annua, which are used in occult practices by believers. The poachers modified the penises of monitor lizards to resemble the plant roots, (which look like folded hands), and made it even more complex for investigators to make an accurate identification.

The CCMB researchers said that forensic genetic evidence is a powerful tool to secure convictions in wildlife crimes. “The bifurcated hemipenes (gonads) of any of the four species of Monitor lizards found in India are illegally traded under the name ‘Hatha Jodi’ (a plant root from Martynia annua). A rare plant root is misrepresented as a powerful charm capable of bringing property and good fortune to its possessor. As a result, there is a suspected large-scale poaching of monitors in India to fuel the trade of ‘Hatha Jodi’,” the CCMB researchers in the paper said.

Monitor lizards are copiously poached for their meat, which is considered a delicacy and assumed to have medicinal properties. Studies have documented that the products prepared from the monitor lizards are used to treat various diseases, i.e., asthma, haemorrhoids, rheumatism, and arthritis. The genital organs from Monitor lizards are traded in the name of ‘Hatha Jodi’, the root of the Tiger’s Claw plant and used for human welfare, the researchers said.

Genetics role in ovarian cancer

The Medical Minute: Genetics play big role in ovarian cancer In 2024, about 19,680 women in the United States will receive a new diagnosis of ovarian cancer and 12,740 women will die from the disease, said Dr. Shaina Bruce , a gynecologic oncologist at Penn State Cancer Institute . The median age of all patients who develop ovarian cancer is 63. Historically, women at increased risk for ovarian cancer are recommended to have their fallopian tubes and ovaries removed when they have completed having children. Taking that step to protect themselves comes at a heavy price ― surgical menopause. But Bruce said medical science is catching up with ovarian cancer. Studies could lead to new methods for preventative care and the surgery needed to lower risk may be easier than it once was. Below, during Gynecologic Cancer Awareness Month, Bruce discusses the disease and why acting to reduce your risk is worth it. What’s the connection between heredity and ovarian cancer? About 25% of all cases of ...

Migration in Population Genetics

  Migration in Population Genetics Migration in population genetics refers to the movement of individuals-and therefore their genes -between different populations of the same species. This gene flow alters allele frequencies, increasing genetic diversity within populations while reducing genetic differences between them. Migration can counteract the effects of genetic drift and inbreeding , introduce new alleles , and influence evolutionary processes such as adaptation and natural selection. The rate, direction, and scale of migration play a crucial role in shaping population structure, evolutionary potential, and long-term species survival, especially in fragmented habitats or changing environments.

Chromosomal Abnormalities

  Chromosomal Abnormalities Chromosome abnormalities refer to structural or numerical changes in chromosomes that can disrupt normal genetic function, leading to developmental disorders, congenital abnormalities, and various genetic diseases. These abnormalities may arise from errors in cell division, such as nondisjunction or chromosomal breakage, resulting in conditions like Down syndrome , Turner syndrome, Klinefelter syndrome , and various deletion or duplication syndromes. Understanding chromosome abnormalities is essential for genetic counseling, prenatal diagnosis, disease risk assessment, and research in cytogenetics and molecular genetics. Chromosome abnormalities, chromosomal disorders, chromosomal mutations, aneuploidy, structural chromosome abnormalities, nondisjunction, deletion syndrome, duplication syndrome , translocation, inversion, cytogenetics, karyotyping, prenatal diagnosis , genetic testing, genomic instability, Down syndrome, Turner syndrome, Klinefelter syn...
