Heredity
Heredity refers to the process of transmitting genetic characteristics from parents to offspring. Physical traits and even physical defects are known to be hereditary. Also, some mental traits and mental defects are known to be hereditary. (http://www.slideshare.net/GenPsyche/biological-bases)
Nature and Nurture
Both nature and nurture affects all aspects of human behaviour. “Nature refers to all the evolutionary factors that have shaped the genetics that we have inherited from our parents and ancestors. Nurture refers to all the things that have influenced us since we began to develop (from the moment we were conceived).Nature determines the range of our human potential. Nurture affects the ways that our human potential is actualized, being helped or hindered by good or bad environmental inputs.” (http://www.soc.ucsb.edu/faculty/baldwin/classes/soc142/n&n.html)
In the debate versus nature and nurture, nature refers to an individual’s qualities that are inherited; for example nativism. Biological and family factors affect one’s nature. Nurture refers to personal experiences; for example, empiricism or behaviourism. Social and environmental factors affect one’s nurture. (http://www.diffen.com/difference/Nature_vs_Nurture)
Genes
According to Mcgraw-Hill, “Genes, the units of hereditary information, are short segments of chromosomes. Genes combine with other genes to determine our characteristics. There are dominant and recessive genes. Polygenic inheritance is the effect that multiple genes have on behaviors and mental processes. The study of genetics has progressed from the basic experiments of Mendel to molecular genetics and the development of genomes. Genetic methods include selective breeding and behaviour genetics.” (http://highered.mcgraw-hill.com/sites/0072937769/student_view0/chapter3/)
