Apologies all, I'm on the ole iPhone, so typing mite also be dodge! Well the three main modes of inheritance that we decided to look at were autosomal dominant, recessive and sex-linked! From our first session on Thurs, we really tried to make sure we all understood these terms. We tried to give a quick explanation of punnet squares, alleles&pedigrees. After a bit of trial and error (and a bit of time revising genetics!!) I thought that the mode of inheritance might be sex-linked? Sophie I sent an email to everybody in yellow group explaining the rationale behind this, so I can perhaps forward this to you or include it on here!
Dear Hannah Thanks for this. If its not too much of a hassle it would be great to include here, so the group can ask questions if they don't understand it and seek some clarification. Remember to perhaps include hyperlinks to some online resources that you and/or others may find useful. Thanks for being such an active learner and considerate group member.
This blog really is a good idea! After some extra tutoring from my old bioloby teacher, I agree with you Han that its sex-linked, because the autosomal inheritance didn't work in this situation. Slowly, this genetics stuff is starting to make sense! After our lecture, I'm sure it will be much easier to understand! Must remember to bring the laptop in on thursday too so we can begin our powerpoint
I know it's late but I've just had like an "eureka" moment. I finally understand it all after listening to Toby's lecture and going through the powerpoint from Han again. I also agree that it is recessive sex-linked. There can't be any carriers in the family history if the trait is autosomal dominant right? If it is autosomal recessive this means keith's dad has to carry the recessive allele but he doesn't. So the only conclusion is that Keith's condition is recessive sex-linked where the affected allele is carried on the X chromosome. In other words, Keith's dad is unaffected because he carries the undiseased allele on his X chromosome and Keith recieved the diseased allele from his mum. This took me a while to work out! Hopefully we can get our powerpoint started soon.
I actually meant "different.. not fifferent" You will notice that I am not very good at keyboard skills!!"" Apologies....

ReplyDeleteI am glad you like the blog idea Lauren. Why do you think that the autosomal inheritance hasn't worked in this situation ?
