Vedclass · Answer

(A) In $Mirabilis$ $jalapa$ (Four o'clock plant) and $Antirrhinum$ $majus$ (Snapdragon),the inheritance of flower color follows the pattern of incomplete dominance.In this phenomenon,the dominant allele does not completely mask the expression of the recessive allele.When a red-flowered plant $(RR)$ is crossed with a white-flowered plant $(rr)$,the $F_1$ generation produces pink-flowered plants $(Rr)$.This happens because the expression of the red color is not fully dominant over the white color,resulting in an intermediate phenotype (pink).

In $Mirabilis$ and $Antirrhinum$ plants,the flowers appear pink in the hybrid $(Rr)$ condition,which is produced by crossing red $(RR)$ and white $(rr)$ parent flowers. This phenomenon is known as:
