Ok guys
Chapter 1. Random Qs 1.What is a phenotype vs genotype? 2.What is a genetic polymorphism? 3.What are the various modes of inheritance with a few examples of each? 4.What is the recurrence risk for XLinked diseases if the mom is the carrier or if the dad is carrying the mutation? 5.What do you mean by manifesting heterozygote? 6.What is a Barr body? What gene is involved in giving rise to the Barr body? 7. What are the features of mitochondrial inheritance? 9.What is incomplete penetrance? 10. What is the pathogenesis in Prader Wili & Angelman's?

i don't know about you guys but that Hardy Weinberg exception in cases of Autosomal Dominant and Xlinked situations bugged me to no end. Everytime I read it and thought I had grasped it it slipped away. I had to keep reading it till it sank in.

Hi Quasar. So what was your final understanding of Hardy-Weinberg?

hi susie1
Well, after reading I was trying to work the questions at the end of the chapter and i had trouble getting to the answer. So I went back to the book and read the HWE again . For dominant diseases 2q is the prevalence. And homozygotes for mutation are q squared. In X linked recessive the males are hemizygotes so they have one q . X liked female homozygotes =q squared and to find female carriers the answer is 2q. |
