(B) In $Antirrhinum$ (snapdragon),the inheritance of flower color shows incomplete dominance. When a homozygous red-flowered plant $(RR)$ is crossed with a homozygous white-flowered plant $(WW)$,the $F_1$ generation produces pink-flowered plants $(RW)$. This occurs because the dominant allele $(R)$ is not completely dominant over the recessive allele $(W)$,resulting in an intermediate phenotype (pink) in the heterozygote.
