Question

Suppose the size of a population of marmots is 300. According to genetic drift theory, what is the probability that a newly arisen mutation will become fixed in this population? Select one:a. 1/1200b. 1/100c. 1d. 1/300e. 1/600

Answer 1

E. 1/600

Step-by-step explanation:

Hint:

The probability of fixation of a new neutral mutation is 1/(2N)

Given N as 300

= 1/(2×300)

=1/600

Therefore,

1/600 gives a sure fixation of one allele from the large population
