Incomplete dominance is not blending inheritance because parental characters reappear in F2 generation. ln Mirabilis jalapa, there are two types of pure breeding plants, red flowered and white flowered. On crossing them the F1 plants or hybrids possess pink flowers. On selfing them, F2 generation has plants in the ratio of 1 red: 2 pinks: 1 white-flowered plants with the phenotypic ratio being the same as a genotypic ratio. Genotypic ratio= 1RR: 2Rr: 1rr Phenotypic ratio: 1 Red : 2 Pink : 1 White Both genotypic ratio and phenotypic ratio are same, i.e., 1 :2 :1.

Follow Us: Popular Chapters by Class: When red and white flowered Mirabilis plants are crossed all pink flowers are seen in F1 generation in F1 progeny the expected phenotypic and genotypic ratios are?Both genotypic ratio and phenotypic ratio are same, i.e., 1 :2 :1. When red tailed Mirabilis crossed pink hybrids occur in F1 generation if this pink hybrid is then crossed with the white the phenotypic ratios among the progeny would be?So, the correct option is '1 pink: 1 white'. When a red flower and a white flower are crossed and produce pink offspring what type of interaction is taking place?Figure 21: A cross between a red and white snapdragon will yield 100% pink offspring. This pattern of inheritance is described as incomplete dominance, meaning that neither of the alleles is completely dominant over the other: both alleles can be seen at the same time. When a red flowered plant is crossed with a white flowered plant the F1 generation has pink flowers This is an example of?Incomplete dominance The F1-hybrid plants have a different phenotype (pink flowers) than either of the true-breeding parents. This is an example of incomplete dominance. What will be the ratio of offsprings in a cross between the red flowered and pink flowered Mirabilis jalapa plants red pink 1 1 red pink 3 1 red pink 1/3 red pink 2 3?Complete Answer:
- According to the experiment, when the plant (Rr) made in F1 generation is crossed with dominant plant i.e red coloured Mirabilis plant (RR), the offspring will be pink (Rr) and red (RR). Their genotypic ratio will be 2:2 i.e. 1:1.
What will be the ratio of offspring in a cross between the red Coloured and pink Coloured?Red : pink : white :: 1 : 2 : 1.
What will be the ratio of offspring in a cross between the red Coloured and white Coloured flowers of Mirabilis jalapa in F1 generation?So, the correct option is '1:2:1'. Was this answer helpful?
Which cross would give you the most pink flowered plants in Mirabilis jalapa?This can be seen in the plant snapdragon, where the cross between red and white flowered snapdragon plants results in an offspring having pink-colored flowers. So, the right answer is option B.
