Question
Can a single gene determine who you are? Please read the following article and consider how genes influence our development. Last week we had a great discussion of nature vs. nurture and I think this article offers another look at how complex the "nature" part can actually be. Please pay close attention to the details of chromosomes, genes, and DNA. What makes these girls different from their fathers? In your discussion post please reflect on the science and the implications. http://phenomena.nationalgeographic.com/2013/09/02/the-tenuous-beginnings-of-men Read the article, then right click in the discussion board to participate. You may certainly include opinion and interpretation but please be sure to keep it connected to the science and grounded in studies.Explanation / Answer
In this article, they have spoken about the Swyer Syndrome which is caused due a single gene present on the Y-chromosome, the SRY gene and is the major gene for maleness. This single gene is responsible for switching the course of if the baby will be produced as boy or girl. The switching on of some genes by SRY leads to formation of testes instead of ovaries producing male. Due to mutations, embryo develops into girl despite having the Y chromosome.
Some research shows that SRY can be impacted by many environmental factors and affected by environmental genes that produce a boy by setting it into male path. SRY is one of the gene which is responsible for switching the path and leads to formation of either male or female but not solely the only gene responsible for it. Even thou father and daughter share the same copies of SRY gene, due to the trigger they can form either male or female.
The whole process of identifying who you are doesn’t depend on one single gene. SRY is sort of wobbly and is affected by many other genes. The presence of SRY or mutation does make an impact but not a single gene is responsible for determining the sex of the person.
