Question

fill in the blank: fill in the blank with the correct words.

1. the process by which certain traits become more common in a population because they help organisms survive and reproduce is called __________
2. __________ are features or characteristics that come from an organism’s genes, such as fur color or beak size.
3. scientists use __________ to read the genetic code of organisms and understand which genes control specific traits.
4. a __________ is a random change in dna that can create new traits.
5. the tool called __________ allows scientists to \cut and paste\ dna, editing genes with extreme accuracy.

Explanation:

1. The process described is natural selection, where advantageous traits for survival and reproduction increase in a population.
2. Inherited traits (or simply Traits in the context of genetic inheritance) are features from an organism's genes like fur color or beak size.
3. Genetic sequencing (or DNA sequencing) is used by scientists to read the genetic code and understand trait - controlling genes.
4. A mutation is a random change in DNA that can introduce new traits.
5. CRISPR - Cas9 is the tool that enables scientists to precisely "cut and paste" DNA for gene editing.

Answer:

1. natural selection
2. Traits (or Inherited Traits)
3. genetic sequencing (or DNA sequencing)
4. mutation
5. CRISPR - Cas9
