Question

The genotype of a green stemmed tomato plant is denoted by “GG” and that of a purple stemmed tomato plant as “gg”. When these two plants are crossed
a) What colour of stem would you expect in their F1 progeny

b) Give the percentage of purple stemmed plant if F1 plants are self-pollinated.
In what ratio would you find the green and purple colour in the F2 progeny

Answer 1

Answer:

a)You would get all green colour stemmed plants in F1 progeny.

b)You would get 25% of purple stemmed plants if F1 plants are self-pollinated.the ratio of green isto purple in F2 progeny would be 3:1.

Explanation:

Answer 2

If The genotype of a green stemmed tomato plant is denoted by GG” and that of a purple stemmed tomato plant as “gg”. When these two plants are crossed then :

● Colour of stem would you expect in their F1 progeny will be green as green is dominant over purple colour.

● The percentage of purple stemmed plant if F1 plants are self-pollinated 25 %.

● The ratio would you find the green and purple colour in the F2 progeny is 3:1.
