Answer:
Describing a trait as dominant does not mean it is the most common; it means that it is expressed over the recessive trait. For example, tongue rolling is a dominant trait, controlled by the dominant version of a particular gene (R). Individuals with one or two copies of R will exhibit tongue rolling.
Answer: d. mothering style affecting the developing brain
Explanation:
Epigenetics is the study of features or "phenotypes" which do not involve changes in the DNA sequence. Epigenetics is about how genes are expressed and used instead of the DNA sequence of the genes themselves.
The behaviour of a person's genes depends not only on the DNA sequence of the genes, but also on so-called epigenetic factors. Effects on genes from the external environment can affect disease, and some of these effects can be inherited in humans.
So, Mothering style which affects the brain development is an exampe of epigenetics which do not show any genetic feature.
Hence, the correct option is d.
