Mating of an organism to a double recessive in order to determine whether it is homozygous or heterozygous for a character under consideration, is called

Give differences : Dominance and Recessive

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 $F_2$ 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:

Cross between $F_1$ plant and recessive female plant is called

Self pollination between $Tt$ and $Tt$ plants results into genotype ratio of

The percentage of heterozygous individuals obtained in $F_2$ generation from selfing the plants with genotype $Rr$ would be
