Vedclass · Answer

(d): The inheritance of flower colour in the dog flower (snapdragon or Antirrhinum $sp$.) is a good example which shows incomplete dominance. In a cross between true&shy;breeding red&shy;flowered $(RR)$ and true&shy;breeding white&shy;flowered plants $(rr)$, the $F_1\ (Rr)$ was pink. When the $F_1$ was self&shy;pollinated the $F_2$ resulted in the following ratio, $1\ (RR)$ Red : $2\ (Rr)$ Pink : $1\ (rr)$ White. Here the genotype ratios were $1 : 2: 1$ as in any Mendelian monohybrid cross, but the phenotype ratios had changed from the $3 : 1$ dominant: recessive ratio to $1 : 2 : 1.$

$F_2$ generation in a Mendelian cross showed that both genotypic and phenotypic ratios are same as $1 : 2 : 1$. It represents a case of
