$RR$ $(Red)$ is crossed with $ww$ $(white)$, all the $Rw$ offsprings are pink. This is an indication that $R$ gene is

In Mirabilis jalapa, when homozygous red-flowered and white-flowered plants are crossed, all $F_1$ plants have pink-coloured flowers. In $F_2$ produced by selfing of $F_1$ individuals, red, pink and white flowered plants appear respectively in the ratio of or What will be the ratio in $F_2$ generation if red-flowered variety of Mirabilis jalapa is crossed with white-flowered variety

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

${F_1}$ hybrid is intermediate between the two parents. The phenomenon is

A pink flowered Snapdragon plant was crossed with a red flowered Snapdragon plant. What type of phenotype/s is/are expected in the progeny?

Geno typic and phenotypic ration in the offspring is $1:2:1$ it explain the principle of
