Applying which has the quantity and quality of sheep wool been increased?
Think it through first, then pick an option.
- a Protein C gene
- b Cys E and Cys M genes
- c Coat protein gene
- d Growth hormone gene
Answer and explanation
Correct answer: b Cys E and Cys M genes
The CysE and CysM genes were put into the sheep genome to raise wool quantity and quality.
Why the other options are wrong
- a Protein C gene: Protein C is the gene for raising protein in cow milk, not for wool.
- c Coat protein gene: The coat protein gene is linked to virus resistance, not wool.
- d Growth hormone gene: The growth hormone gene is for size and meat, not for wool.
