Penetrance is the percentage of individuals having a particular genotype, who express the associated phenotype, following statement, are correct about Penetrance.

#Part-A Aptitude & General Biotechnology
  1. Incomplete penetrance of dominant mutant gene must produced mutant phenotype. 

  2. A gene might encode an enzyme that produces a particular phenotype within limited temperature due to complete penetrance

  3. The genotype does always produce the expected phenotype, a phenomenon termed incomplete penetrance.

  4. Penetrance variability of sex influence gene is differ in male and female
