Question

What type of manipulation of dark mice makes them lighter

a) Exposure to UV radiation
b) Genetic modification
c) Diet change
d) Environmental enrichment

Answer 1

The correct answer is genetic modification.

Step-by-step explanation:

The correct answer is b) Genetic modification.

Genetic modification involves altering the DNA of the mice to change their physical characteristics, including their color. By modifying the genes responsible for dark coloration, scientists can create mice with lighter coats. This can be done through techniques such as gene editing or selective breeding.

For example, scientists can use genetic engineering to insert a gene that produces a protein that inhibits the production of dark pigment in the mice. This gene modification will result in mice with lighter coat color.
