An individual with a homozygous genotype for a particular phenotype __

1.	An individual with a homozygous genotype for a particular phenotype ____________ expresses the phenotype.(a) Always(b) Never(c) Sometimes(d) Unknown relationThis question was posed to me in an interview for internship.The origin of the question is Penetrance and Expressivity topic in section Regulating Gene Expression in Eukaryotes of Cytogenetics
Answer» The correct option is (C) Sometimes Easiest explanation: It is not that the HOMOZYGOUS genotype will always express the required phenotype. It MAY or may not express it depending on some FACTORS. This gives the concept of PENETRANCE.
