> May i ask what is Mendelian?

*** It means one gene is responsible for the disorder. Examples of such disorders are Turner Syndrome, etc. They are inherited in specific patterns and based on whether you have the specific gene or not determines whether or not you have the disorder.

All i recall was
> something to do with plants by Mendel.

*** Yes, Mendel studied pea plants. For example, if a pea plant has a form of one gene, the peas will be yellow, but if it has two 'green' copies it will be green. It's a lot easier explained with a picture, unfortunately.

And what
> is the significance of a Mendelian gene to behavioural abnormalities.

**** I don't know of any behavioral abnormalities that are simply inherited like Mendelian disorders are.

Also, would you say
> that homosexuality is a more-than-one-single-gene phenomenon, for example?

*** One of my classmates did a research project on that, and found that most of the researchers today think that multiple genes contribute to it, as well as environment. It's a complex trait.
