A population of 1000 beetles consists of two colour morphs: green (dominant) and brown (recessive). Initially, the frequency of the green allele (G) is 0.6 and the brown allele (g) is 0.4. Over several generations, the habitat changes, resulting in brown beetles having a higher survival rate than green beetles.
Q. Predict the changes in allele frequencies over time with a selection pressure favouring gg.
Group of answer choices:
A. there will be no change
B. g will increase
C. G will increase

Sagot :

With a selection pressure favoring the gg genotype (brown beetles), the brown allele (g) will increase in frequency over time. So, the correct prediction is that g will increase.
