In certain plant species, red flower colour is incompletely dominant to white flower colour (the heterozygote is pink) and tall stems are completely dominant to dwarf stem. If a tall pink plant $(TtRr)$ is crossed with a tall white plant $(TTrr),$ which one of the following type of plants would be produced in the offsprings?
Tall pink and tall white
Dwarf pink and tall red
Dwarf red and tall pink
Tall pink and dwarf white
The phenotype of an individual may be affected if the modified allele produces
$(a)$ No enzyme at all
$(b)$ The normal/less efficient enzyme
$(c)$ $A$ non-functional enzyme
$RR$ $(Red)$ is crossed with $ww$ $(white)$, all the $Rw$ offsprings are pink. This is an indication that $R$ gene is
In case of incomplete dominance in $F_2$ generation
$F_2$ generation in a Mendelian cross showed that both genotypic and phenotypic ratios are same as $1 : 2 : 1$. It represents a case of
Geno typic and phenotypic ration in the offspring is $1:2:1$ it explain the principle of
