Question

which methods of changing genes offer the most exact control over an organisms traits? (select the two correct answers.) (1 point) letting natural reproduction happen over time. changing the dna of an organism directly. choosing animals with desired traits to mate. breeding two different kinds of plants. hoping for useful random genetic changes. using gene editing tools like crispr.

Explanation:

• Letting natural reproduction happen over time is a slow and random process with no exact control.
• Changing the DNA of an organism directly allows for targeted modification.
• Choosing animals with desired traits to mate (selective breeding) has some control but is less precise than direct DNA change.
• Breeding two different kinds of plants (hybridization) is a form of selective breeding with limited precision.
• Hoping for useful random genetic changes is, as the name suggests, random.
• Using gene - editing tools like CRISPR is a highly precise method of changing genes.

Answer:

Changing the DNA of an organism directly, Using gene editing tools like CRISPR.
