Albinism

... Genomic Imprinting. I know it's parent-specific gene expression, but my question is, what is the difference between it and normal expression? eg//ALBINISM AA-Normal pigmentation Aa-Carrier but no albino phenotype aa-Albinism In genomic imprinting, it says that one allele is masked by the other ...

... the probability to be a healthy carrier of the albinos gene in the general population and use it to calculate the probability of carriage of albinism for those individuals. Or you assume that it is to small to be relevant, and just assume that they are AA. Note that II-2 has only 50% of being

... of inheritance is involved. My ans: autosomal recessive #2 is to write the genotype for each individual using A for normal pigmentation and a for albinism and if genotype is unknown, A_ This is where I'm having a bit of difficulty. My ans: Gen I: Aa Aa AA aa Gen II: A_ Aa aa Aa Aa Aa AA Gen III: ...
