Vedclass · Answer

(A) In snapdragon $(Antirrhinum \, sp.)$, the inheritance of flower color shows incomplete dominance.When a homozygous red-flowered plant $(RR)$ is crossed with a homozygous white-flowered plant $(rr)$, the $F_{1}$ generation produces pink-flowered plants $(Rr)$.This happens because neither of the two alleles is completely dominant over the other, resulting in an intermediate phenotype.Therefore, both the Assertion and the Reason are correct, and the Reason is the correct explanation of the Assertion.

$A$ : In snapdragon, $F_{1}$ plants do not have red or white flowers.
$R$ : It is intermediate inheritance with neither of the two alleles of a gene being dominant over each other.
