Answer:
74%
Explanation:
The frequency in such cases (diallelic cases) is estimated by following formula which is attached in the image:
So as per our question, the frequency of the "R allele" as per data given below will be as under:
58 red-phase (RR)
32 cross-phase (RS)
10 black/silver-phase (SS) foxes
Total plants = 58 + 32 + 10 = 100
f(R) = 58 x 2 + 32/ 2 (58+32+10)
= 116 + 32 / 200
= 148/200
= 0.74 i.e. 74%
