After an exceptionally rainy spring, there is no longer a barrier between the populations, and some individuals migrate inland from the coast. consequently, 20 % of individuals in the new inland population are originally from the coastal population. calculate the spotted allele frequency for the inland population after migration, q combined . round the answer to the nearest hundredth.

Answer

After inland population after migration allele frequency is 0.62 or 62%

Explanation:

Given,  

Coastal striped phenotype freq. = 0.22

ss = 0.22

= 0.22

Similarly, inland striped phenotype freq. = 0.43

= 0.43

=

= 0.4690

= 0.47 i.e. 47%

= 0.655

= 0.66 i.e. 66%

the migration range (m) is given as 20%

m= 0.2

allele freq. after migration = pre migration + ∆q

here,                  

∆q = change in the allele frequency

or                    

migration of allele freq. from coastal to inland

=

= 0.2 (0.47 – 0.66)  

=

= - 0.0382    

∆q = -0.04   i.e. 4%
