The inheritance of gene expression patterns, in the absence of the initiating signal, is called what
Veronika [31]

The inheritance of gene expression patterns, in the absence of the initiating signal, is called Epigenetic regulation.

Epigenetic changes can be defined as inherited variations which are not present in the DNA sequence. Gene expression is regulated at different levels and not merely in response to DNA modifications. Examples of epigenetic control include DNA methylation, histone deacetylation and mi-RNA expression.

Epigenetic mechanisms add an adaptive layer of control in the regulation of gene expression that allows an organism to adapt to a dynamic environment.

Epigenetic regulation increases the functional intricacy of deoxyribonucleic acid (DNA) by changing chromatin structure, nuclear organization as well as transcript stability.

Codominance.

Codominance occurs when, for example, a Dominant Blue color gene for a leaf crosses with a Dominant White color gene for a leaf. The genotype would be BW. This would result in, for example, a blue and white spotted leaf color. INCOMPLETE dominance occurs when both dominant alleles blend together, resulting in, eg, a pale blue color resulting from the blue and white colors mixing.

The sugar glider in Australia and the flying squirrel in North America are both small mammals with large expanses of loose skin
Flauer [41]

Answer:

Each have adapted in very similar ways to similar habitats.

Explanation:

According to Darwin, given a similar set of conditions, two different organisms can adapt in the same direction. Here, the sugar glider inhabits Australia and the flying squirrel inhabits North America. There is a huge distance between their locations and also they are two different species with no direct evolutionary relation. However, because of the similar conditions present in their habitats, they developed same traits over the time. Both of them live in forested areas so they developed loose skin between their limbs which allowed them to glide freely between the trees.
