Study Notes
Genetic Variability and Mutations
- Genetic mutations serve as the ultimate source of variability in populations, introducing new traits and characteristics.
- Mutations result in changes to DNA, which can lead to alterations in physical forms, functions, or behaviors of organisms.
Genetically Modified Organisms (GMOs)
- GMOs can help mitigate agricultural challenges such as pest infestations and adverse environmental conditions.
- The purpose of adding genes for insect resistance to crops is to enhance their protection against pests, reducing the need for chemical insecticides.
- Inserting specific genes into crops allows for improved traits, such as increased yield, enhanced nutritional content, or better stress resistance.
Controversies Surrounding GMOs
- GMOs are often controversial primarily due to public concerns regarding safety, environmental impact, and ethical considerations.
- The introduction of drought-resistant genes aims to improve crop survival and productivity in arid and drought-prone regions.
Public Perception and Regulations
- The terms 'mutation' and 'mutant' carry negative connotations in public discourse, leading to fears about the safety and unpredictability of genetically altered organisms.
- The banning of GMO potatoes in Peru stems from cultural and health concerns, reflecting local resistance and preference for traditional farming practices.
Genetic Modification Terminology
- The intentional modification of genes is referred to as genetic engineering, a process aimed at achieving desired traits in organisms.
