An adaptation is adapted to suit the environment as every environment is different.
Different environment aids to different kind of adaptations that perfectly suits the animals living there.

The animals that live in the polar regions have thick fur to provide insulation and heat to live in polar region.

D. before cells without a true nucleus
The resulting mice will be induced with the changed gene either on or off. The offspring will have altered genes if both the alleles have the trait. This is a heritable change.
Explanation:
Making gene on or off is a process of gene regulation when one of the gene is methylated or histone modification to prevent access to transcription factors hence no expression of the protein. This process is called epigenetics.
The resulting progeny in mice will receive the allele of on or off the gene. Such genes with altered allele are also called as
The altered genes will be expressed in the resulting progeny of mice.
The epigenetic genes can be reverted with environmental effects in the offspring paramutable alleles. They are heritable.
