Question
1. In which of the following scenarios does allele q have the highest likelihood of going to fixation in the future, assuming that genetic drift is the only evolutionary force?
a. allele q entered the population as a new mutation not long ago, but presently has a frequency of 0.44
b. allele q is a brand-new mutation found in only one individual in a large population
c. allele q previously had a frequency of 0.73 but now has a frequency of 0.51
d. allele q is presently found only in heterozygous individuals that also have allele Q
e. allele q is lethal
Explanation / Answer
Ans a) allele q entered the population as a new mutation not long ago , but presently has a frequency of 0.44
Frequency of 0.44 is quite good , if the allele has recently entered into the population . Rest if the frequency is decreasing or the allele has lethal effects , it is not likely to stay in the population .
The nature selects the trait which is most favourable in the population , unfavourable ones are gradually eliminated.
