Question

What is the basic understanding of genetic heredity? Is DNA code must be understood but molecular details are not needed? What is the relation between genes, evolution, and natural selection? Is the distinction between learned behavioral adaptations and innate behavioral adaptations important? In this context, what meant by “3 sources of knowledge in behavior”? What are the basics of behavior genetics and the notion of the heritability estimates? Is gene-environment interactions are quite important as well?

Answer 1

• Genetic heredity is the process of passing genetic material from one generation to another.DNA is the genetic hereditary material derived from the molecules of nucleotides bases that are heterocyclic in nature.These are molecules are from purine or pyrimidine.So to understand the DNA code molecular details (purine or pyrimidine) are indeed necessary.
• Genes, evolution and natural selection are related to each other in the following way. Evolution is the process of continuously changing organisms' genetic material over generations.Furthermore, natural selection is the process where organisms which are comparatively better adapted than others,to their environment are able to survive and reproduce.
• Distinction between learned behavioral adaptations and innate behavioral adaptations: Innate behavioral adaptations are the one that are present by birth and does not need any external intervention for initiation such as, nest building.Learned behavioral adaptations are the behaviors learnt through observation, trial and error such as, hunting.

Good Luck!
