Explanation / Answer

9) Epistasis - an allele of one gene masks the effect of the allele of the same gene

10) Penetrance - individuals with the same genotype have related phenotypes that vary in intensity

11) Pleiotrophy - a gene affecting more than one phenotype

12) There is alteration of generations in the expression of disease. Both males and females are affected. So, the pattern of inheritance is autosomal recessive. (Option a).
