If two plants heterozygous for both genes are crossed, what will be the ratio of blue to nonblueflowers?

In a garden of plants of the same species 705 plants have red flowers while 224 had white flowers (i) Work out the ratio of the red to white flowers (ii)Using letter R to represent the dominant gene, work out the cross between F1 offspring and a white flowered plant (iii)what is the genotypic ratio from the cross in(i) above

Let Y = yellow and y = green, and R = round and r = wrinkled. You cross YYRR peas with yyrr peas. All of the F1 individuals are yellow and round with a genotype of YyRr. You then perform an F2 cross and get the expected 9:3:3:1 phenotypic ratio. What proportion of the F2 plants are expected to be heterozygous for both traits?Multiple Choice1/161/49/161/2

In the offspring of the two sunflowers above, determine the likely ratio of homozygous tall to heterozygous genotypes. 1:11:2:11:33:1I'm not sure

Sometimes, when Mendel crossed two pea plants with each other, he obtained a phenotypic ratio of 3:1 purple-flowered pea plants to white-flowered pea plants. These results are consistent with which set of parents?Multiple ChoiceHomozygous purple pea plant and homozygous white pea plantHeterozygous purple pea plant and homozygous purple pea plantHeterozygous purple pea plant and homozygous white pea plantHeterozygous purple pea plant and heterozygous purple pea plant

Now, consider a brown colored maize plant is crossed with another maize plant producing the following offspring [Green color is dominant over brown color; follows Mendelian inheritance pattern] If these maize plants are crossed among themselves, what is the expected genotypic ratio of the offsprings? 3:1 1:1 1:2:1 1:1:1:1
