What distinguishes classical breeding from modern genetic engineering techniques?
What distinguishes classical breeding from modern genetic engineering techniques?
- Classical breeding is more precise and targeted than genetic engineering.
- Classical breeding introduces entirely new genetic material, while genetic engineering only modifies existing traits.
- Classical breeding relies on natural mating processes, whereas genetic engineering uses molecular techniques. (correct)
- Classical breeding is faster and more efficient compared to modern genetic engineering.
Which of the following represents a key step in the classical breeding process?
Which of the following represents a key step in the classical breeding process?
- Direct insertion of genes into the target organism.
- Selection of parents that exhibit desired traits. (correct)
- Using enzymes to cut and paste DNA sequences.
- Creating genetically modified organisms (GMOs) for specific traits.
What is the primary goal of genetic engineering?
What is the primary goal of genetic engineering?
- To precisely modify the traits of a target organism using molecular techniques. (correct)
- To enhance the biodiversity of a given species.
- To preserve traditional breeding methods without introducing new traits.
- To create random mutations in an organism's DNA.

Genetic Engineering
Genetic Engineering
Using molecular techniques to alter an organism's traits, involving the introduction of new traits or enhancement of existing ones.

Study Notes
- GENBIO REVIEWER
Genetic Engineering
- Genetic engineering involves using molecular techniques to change the traits of an organism
- New traits are introduced
- Present traits are enhanced
Classical Breeding
- Classical Breeding serves as a traditional method of genetic engineering
- Mating organisms with desirable qualities is part of the process
Process
- Determine significant traits that are to be chosen
- Select parents that exemplify the traits
- Choose the best offspring from parents to produce the next generation
- Repeat the process
Recombinant DNA technology (rDNA)
- Recombinant DNA technology (rDNA) is considered a modern way of genetic engineering
- Joining DNA molecules together takes place

Description
This section discusses genetic engineering techniques. It contrasts modern methods like recombinant DNA technology with classical breeding. The classical breeding process involves selecting traits, choosing parents, and repeating the selection to improve offspring.
