Abook describes a future society in which the dna of each child is mapped and the child is raised in a school that emphasizes development in the child’s area of highest potential. which statement best describes the author’s central theme? traits that are acquired through experiences can overcome traits that are genetically encoded. environmental influences can improve the expression and performance of inherited traits. traits that are determined by genetic makeup will be expressed despite what a person might learn. inherited traits can be changed through the proper environmental influence if identified early in life.

The correct answer would be "Environmental influences can improve the expression and performance of inherited traits".  

The expression of genes in an organism is highly influenced by both external and internal environment.

Internal environment includes metabolism, hormones et cetera.

External environment factors include light, temperature, drugs, chemicals et cetera.

For example, it is believed that sports activities tend to increase the mental and physical health of a person.

The genes associated with pigmentation of skin or fur are highly influenced by light and temperature. For example, organisms inhabiting the regions with lower temperature tend to have bright or light colored skin whereas the organisms which inhabit the regions with high temperature tend to have dark colored skin.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
