Which one of the following can be explained on the basis of Mendel's Law of Dominance? A. Out of one pair of factors one is dominant and the other is recessive. B. Alleles do not show any expression and both the characters appear as such in F2F_2 generation. C. Factors occur in pairs in normal diploid plants. D. The discrete unit controlling a particular character is called factor. E. The expression of only one of the parental characters is found in a monohybrid cross. Choose the correct answer from the options given below:

Options

  1. AA, C, D and E only
  2. BB, C and D only
  3. CA,B,C,D\mathrm{A}, \mathrm{B}, \mathrm{C}, \mathrm{D} and E
  4. DA, B and C only

Correct answer

A. A, C, D and E only

Step-by-step solution

According to Law of Dominance (1) Characters are controlled by discrete units called factors (2) Factors occur in pairs (3) In a dissimilar pair of factors one member of the pair dominates (dominant) the other recessive The law of dominance is used to explain the expression of only one of the parental characters in a monohybrid cross. Law of segregation is based on the fact that the alleles do not show any expression and both the characters are recovered as such in F2\mathrm{F}_2 generation
