A researcher genetically engineers a mouse strain by deleting the mouse lyst gene and replacing it with the polar bear lyst gene. Predict the most likely difference in phenotype of the transgenic mouse strain compared to the wild-type mouse strain. Justify your prediction.

The transgenic mouse must present fur without pigmentation, or with reduced pigmentation.

Explanation:

As seen in the question above, a group of scientists genetically engineers a mouse strain by deleting the mouse lyst gene and replacing it with the polar bear lyst gene. This will modify the genotype of the mice making them transgenic mice different from ordinary mice.

As you may already know, polar bears have pigment-free fur, for that reason, these animals have white fur, allowing them to camouflage themselves in the environment in which they live.

When the genes of these bears are not added to the genome of a mouse, we can expect the mouse fur to change, appearing without any type of pigmentation, becoming totally white, or, appearing lighter than normal.

I predict that the transgenic mouse fur will be lighter.

Explanation:

the most likely difference in phenotype of the transgenic mouse strain compared to the wild-type mouse strain is that The mouse fur will be lighter because the Polar bear lyst gene is known with its lack of pigment or white hair. since the mouses lyst gene has been deleted and it now has the polar bears lyst gene, its fur shows this characteristic of the polar bear, and makes it different from the wild mouse.
