what is the biological theory and psychosocial theory?
When you are looking at the concept of homosexuality in regards to biological and psychosocial theories you are essentially looking at the concept of nature versus nurture. What this means is you are looking at whether someone being homosexual is a result of a biological predisposition to this preference or if they are influenced by their environment to be homosexual.
If the biological perspective is taken this is the nature side of the argument which will support that an individual who is homosexual is genetically created this way meaning it is within their biology to be attracted to the same sex.
If the psychosocial perspective is taken then the nurture side of the argument will support that the individuals environment shaped and conditioned the individual to be attracted to the same sex.
