The $F_1$ hybrid is intermediate between the two parents. This phenomenon is known as:

In Antirrhinum,two plants with pink flowers were hybridized. The $F_1$ plants produced red,pink,and white flowers in the proportion of $1$ red,$2$ pink,and $1$ white. What could be the genotype of the two plants used for hybridization? Red flower color is determined by $RR$,and white by $rr$ genes.

When the progeny obtained in the $F_1$ generation shows the expression of both genes present in its genotype, but the expression is not complete, which of the following characteristics can be applied?

Incomplete dominance is found in

What does the Andalusian fowl exhibit?

In $Mirabilis \text{ jalapa}$, the phenotypic ratio of red : pink : white flowers in the $F_2$ generation is ....
