for q 7,mitochondrial inheritance dis are always transmitted from mother to all the siblings,as mother is affected,there is 100%chance of each child having the dis.

q5 shd be prevalence of dis,as ppv depends on prevalnce,if prevalence is low,very high specificity test also will hav low predictive value as the fp will b more than tp..

4-9 is a male not female....n his partner dsnt hav ds
