A plant with red flowers was crossed with another plant with yellow flowers. If $F_1$ showed all flowers orange in colour, explain the inheritance.
This is due to the incomplete dominance as the $F_{1}$ do not resemble either of the two parents and is in between the two. As there is blending of traits.
In poultry, new comb colour appears by colaboration of two dominant gene is
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, $2$ pinkand $1$ white. What could be the genotype of the two plants used for hybridization ? Red flower colour is determined by $RR$, and white by $rr$ genes?
$RR$ $(Red)$ is crossed with $ww$ $(white)$, all the $Rw$ offsprings are pink. This is an indication that $R$ gene is
Assertion : In Mirabilis, selfing of $F_1$ pink flower plants produces same phenotypic & genotypic ratio.
Reason : Flower colour gene shows incomplete dominance.
In Mirabilis jalapa, when homozygous red-flowered and white-flowered plants are crossed, all $F_1$ plants have pink-coloured flowers. In $F_2$ produced by selfing of $F_1$ individuals, red, pink and white flowered plants appear respectively in the ratio of or What will be the ratio in $F_2$ generation if red-flowered variety of Mirabilis jalapa is crossed with white-flowered variety
