When is Required NEET BIOLOGY SYLLABUS Genetics and Evelution
The genetics and evolution topics are a part of the NEET Biology syllabus. NEET (National Eligibility cum Entrance Test) is conducted by the National Testing Agency (NTA) in India for admission to undergraduate medical courses. The specific dates for the NEET exam may vary each year, and it’s recommended to check the official NTA website or the NEET information bulletin for the most up-to-date information.
Typically, the NEET exam takes place once a year, usually in the months of May or June. The syllabus for NEET Biology, including genetics and evolution, is based on the NCERT (National Council of Educational Research and Training) curriculum for class 11 and class 12. It’s important to thoroughly study the prescribed syllabus and topics to prepare effectively for the NEET Biology section.
Case Study on NEET BIOLOGY SYLLABUS Genetics and Evelution
Genetic Disorders and Evolutionary Implications
Introduction: In the NEET Biology syllabus, genetics and evolution are important topics that hold significant relevance in understanding the functioning of living organisms. This case study explores the connection between genetic disorders and their evolutionary implications. It demonstrates how mutations can lead to genetic disorders and discusses the impact of these disorders on the process of evolution.
Case Study: Mr. and Mrs. Sharma, a young couple, are planning to start a family. They both have a family history of a genetic disorder called sickle cell anemia, which is caused by a mutation in the hemoglobin gene. Sickle cell anemia is characterized by the production of abnormal hemoglobin, leading to distorted red blood cells and various health complications.
Understanding the Genetics: Sickle cell anemia is an autosomal recessive disorder. Both parents must carry a copy of the mutated gene for their child to inherit the disorder. Mr. Sharma is a carrier of the sickle cell mutation, as he has one normal copy and one mutated copy of the hemoglobin gene. Mrs. Sharma, on the other hand, does not carry the sickle cell mutation.
The Risk of Inheritance: If both parents are carriers of the sickle cell mutation, there is a 25% chance that their child will have sickle cell anemia, a 50% chance that the child will be a carrier like Mr. Sharma, and a 25% chance that the child will have two normal copies of the gene.
Evolutionary Implications: Sickle cell anemia is more prevalent in regions where malaria is endemic. It is hypothesized that carriers of the sickle cell mutation have a selective advantage against malaria. The malaria parasite cannot survive as well within red blood cells affected by sickle cell anemia. Consequently, carriers of the sickle cell mutation are more resistant to malaria, increasing their chances of survival in malaria-endemic regions.
This case study highlights the interplay between genetic disorders and evolution. While sickle cell anemia is a detrimental condition, the presence of the sickle cell mutation in the population demonstrates the evolutionary advantage it confers in malaria-endemic regions.
Conclusion: The study of genetics and evolution in the NEET Biology syllabus provides a deeper understanding of how genetic disorders can arise and impact the process of evolution. Genetic mutations can lead to various disorders, some of which may have unexpected advantages in specific environments. By exploring these concepts, aspiring medical professionals gain insights into the complexities of genetic inheritance, the development of disorders, and the evolutionary dynamics within populations.
