In a particular species of plant, seed color is determined by a single gene. Gray seed color is dominant to white seed color. In a cross, 702 gray seeds and 698 white seeds were produced.

What is the most likely genotype of the parents?

A.

Gg × Gg
B.

GG × gg
C.

Gg × gg
D.

GG × Gg

Answer #1

Answer - option no c is correct because as we can see that punnet cross of the parents in the option no C , the outcome is similar to asked in the question(702 gray : 698 white) which is about 50 % gray and about 50% white

see the complete explanation below

A - genotype of parent Gg x Gg

G g
G GG (gray) Gg (gray)
g Gg (gray) gg (white)

B - genotype of parent GG X gg

g g
G Gg (gray) Gg (gray)
G Gg (gray) Gg (gray)

C - genotype of parent Gg X gg RESULT - 50% gray 50% white

G g
g Gg (gray) gg (white)
g Gg (gray) gg (white)

D - genotype of parent GG X Gg

G G
G GG (gray) GG (gray)
g Gg (gray) Gg (gray)

Seed color in radishes is determined by a single gene. Radish seeds come in three colors: purple, brown and orange. A gardener plants all purple seeds in his isolated garden and collects the resulting seeds produced. 157 purple, 73 brown and 81 orange seeds were collected. What type of inheritance does this represent? What is the most probable genotype of each parent? Based on your answer above, what genotypic and phenotypic ratios are expected in these progeny?

Suppose that the leaf color of a certain plant is controlled by one gene locus with two alleles. At this locus the G allele is associated with orange color and is dominant to the g allele, which is associated with green color. You have a plant with orange leaves, but do not know whether that plant's genotype is GG or Gg. Which of the following would help you determine the plant's genotype? Cross two true-breeding, orange-leaved plants to each other...

You are studying inheritance of various characters in marigolds including flower color (purple or blue), seed color (white or brown) and seed shape (round or oblong). When you cross a plant that is true breeding for blue flowers, white and oblong seeds with a plant that is true breeding for purple flowers, brown and round seeds you find that all of the offspring have blue flowers, and round, white seeds. You then cross these F1 plants with each other and...
