1.	The genes that Mendel worked with were__________________(a) Variable in penetrance and expressivity(b) Variable in penetrance only(c) Variable in expressivity only(d) 100% penetrant with 100% expressivityI had been asked this question during an interview.Question is from Penetrance and Expressivity in chapter Regulating Gene Expression in Eukaryotes of Cytogenetics
Answer» The correct CHOICE is (d) 100% penetrant with 100% expressivity The best I can explain: The 7 sets of pea genes that Mendel worked with showed 100% penetrance and 100% expressivity. Due to this the dominant and recessive genes always expressed the different phenotype to the FULL degree of expression.
