Answer:
E. 6:3:3:2:1:1
Explanation:
Look at the attached picture to see the Punnett square for your problem.
The cross for this is snapdragons who are heterozygous for both traits so the cross would be:
<em>TtRr x TtRr</em>
As you can see in the image, you have the following genotype combinations with the corresponding phenotype combinations:
GENTOTYPE PHENOTYPE NUMBER
TTRR Tall - Red 1
TtRR Tall - Red 2
TTRr Tall - Pink 2
TtRr Tall - Pink 4
TTrr Tall - White 1
Ttrr Tall - White 2
ttRR Short - Red 1
ttRr Short - Pink 2
ttrr Short - White 1
The following phenotype combinations in summary would then be:
Tall - Pink: 6
Tall - Red: 3
Tall - White: 3
Short - Pink: 2
Short - White: 1
Short - Red: 1
So the ratio is 9:3:3:2:1:1
