I recently read about heritability in my textbook. Since it is a concept that I don't completely understand, I thought that I should write my first weekly blog assignment about heritability. The book defines heritability as the proportion of variation among individuals that we can attribute to genes.
I found an article on EbscoHost about a recent study that was done in Ohio on 2,900 pairs of twins. They were trying to research heritability, especially how they are likely to take risks, perceive sounds, and how similar their religious beliefs are.
It is hard for me to make a connection to my personal experiences with heritability because I'm not exactly sure which traits I inherited genetically and which traits I developed due to environment. However, I do have certain things in common with both of my parents, so it makes sense that I may have inherited these traits from them. I think that heritability is how many of these inherited traits I have in common with other people whom I'm not related to who have also inherited the same traits genetically.
Heritability has a lot to do with heredity because it depends on the traits you inherit. It also depends on your interactions with other people, because these people's genetically inherited traits may be the same as yours, and you must interact with them in order to compare these traits.

Mariah,
ReplyDeleteI had trouble understanding heritability as well. I also would like to say that I think it was very smart of you to look up articles about the topic you didn't understand. The article you chose was also a smart choice and related closely to the subject.
Your own definition and your views on heritability and its relation to heredity makes a lot of sense. Your blog assignment definately made me look at heritability differently in the sense of understanding it. Thank you.
I also thought that your definition of heritability was very good, it helped me understand the subject better. I also have trouble knowing what i inherited and what i learned of experience. I obviously got my looks from genetics, but my personality...i'm not sure. My dad and i are a lot a like so maybe it could be genetics because how much can you learn from seeing how people around you act.
