Title: Part C- Determining genotypes in autosomal recessove pedigrees Post by: LISAZ1984 on Feb 27, 2014 Pedigree 3 from Part A is shown below. Recall that this pedigree shows the inheritance of a rare, autosomal recessive condition.
Note that individual II-3 has no family history of this rare condition. Fill in the genotypes for the indicated individuals in the pedigree by dragging the best label to the appropriate location. Labels can be used once, more than once, or not at all. Please see attached diagram Title: Re: Part C- Determining genotypes in autosomal recessove pedigrees Post by: padre on Feb 28, 2014 I suggest reading up on this thread: https://biology-forums.com/index.php?topic=77247.0 (https://biology-forums.com/index.php?topic=77247.0)

Title: Re: Part C- Determining genotypes in autosomal recessove pedigrees Post by: padre on Mar 2, 2014 I will mark the thread solved. Feel free to change it back.
Title: Re: Part C- Determining genotypes in autosomal recessove pedigrees Post by: Sdoggggy on Mar 10, 2014 Isnt that the answer for autosomal dominant pedigree? Not the recessive type??
Title: Re: Part C- Determining genotypes in autosomal recessove pedigrees Post by: padre on Mar 10, 2014 How would the answer change, do you know?
Title: Re: Part C- Determining genotypes in autosomal recessove pedigrees Post by: Sdoggggy on Mar 11, 2014 Wouldnt affected people become rr? Carriers are still Rr, and RR are for people with no family history of the autosomal recessive disease?
Title: Re: Part C- Determining genotypes in autosomal recessove pedigrees Post by: dramadeur on Mar 21, 2014 So what's the answer? I tried as in picrelated, - but it's wrong.
rr = homozygous for the recessive, condition-causing allele. Rr = heterozygous carrier. RR = homozygous for the wild-type allele. R_ = an unaffected individual whose genotype cannot be determined. There's no explanation for autosomal recessive condition :( Do III-2, III-3, III-4 are all R_? If yes, why? We do know history of one of III-4 parents... or do we have to know history of both parents? Also, apparently II-3 is RR (homozygous for the wild-type allele) WTF???? Doesn't make sense.

Title: Re: Part C- Determining genotypes in autosomal recessove pedigrees Post by: vaguilera on Mar 27, 2014 This question, and what the answer ended up being was really confusing! If anyone could explain it that would be super helpful! :)
Title: Re: Part C- Determining genotypes in autosomal recessove pedigrees Post by: zxcvbnm,. on Mar 27, 2014 I totally agree this stuff is really confusing
