An island population of 50 snakes is fixed for allele v. A population on a nearby continent has alleles R andr in Hardy-Weinberg equilibrium. A small group of 25 snakes move from the continent to the island. 9 of the snakes that move are 'rr', 12 are 'Rr' and 4 are 'RR.
What is the most likely relationship between the frequency of alleler in the group of snakes that move to the island compared to the frequency of allele r on the continent? O freq(r) in the snakes that move equals freq(r) on the continent. O freq(r) in the snakes that move is less than freq(r) on the continent. o freq(r) in the snakes that move fluctuates around an equilibrium point equal to the freq(r) on the continent. O freq(r) in the snakes that move is greater than the freq(r) on the continent. O freq(r) in the snakes that move is different from freq(r) on the continent.
What expression can be used to calculate the frequency of allele 'r' on the island after the arrival of the new group of snakes from the continent, assuming no genetic drift? Let p = freq(r) on island after new snakes arrive pl = freq(r) on island originally (before new snakes arrive from continent) pC = freq(r) on the continent p = pl(50/75) + PC(9/25) + PC(0.5)(12/25) O p = pl(50/75) + PC(25/75) O p = pl(50/75)+ pC19 + 12)/75 none of these expressions is correct Op=119+50)/75
Assume there is no genetic drift. What is the new frequency of the rallele on the island after the snakes move there? Choose the closest answer to your calculated value. O 0.17 O 0.87 O 0.66 O 0.70 O 0.80
