Which of the following would be a desirable trait that scientists may want to introduce into a transgenic plant?

• A. Decreased tolerance to drought conditions
• B. Lower nutritional value of edible parts
• C. Reduced ability to perform photosynthesis
• D. Increased resistance to insect pests

Answer: (D)

Verified step by step guidance

1. Understand the concept of transgenic plants: Transgenic plants are genetically modified organisms (GMOs) where scientists introduce specific genes to enhance desirable traits or suppress undesirable ones. These traits can improve agricultural productivity, environmental resilience, or nutritional value.
2. Analyze the options provided: Evaluate each trait to determine whether it would be beneficial or detrimental to the plant's survival, agricultural value, or usability. For example, decreased tolerance to drought conditions would harm the plant's ability to survive in dry environments, making it undesirable.
3. Focus on the desirable trait: Increased resistance to insect pests is a beneficial trait because it helps protect the plant from damage caused by insects, reducing the need for chemical pesticides and improving crop yield.
4. Consider the implications of genetic modification: Introducing genes for insect resistance can involve incorporating genes from other organisms, such as Bacillus thuringiensis (Bt), which produces proteins toxic to certain insects but safe for humans and other animals.
5. Conclude why increased resistance to insect pests is desirable: This trait enhances the plant's ability to thrive in agricultural settings, reduces reliance on chemical pesticides, and supports sustainable farming practices, making it a highly desirable trait for transgenic plants.
