Did the frequency of the bb individuals decrease with successive generations? Why or why not? Yes the frequency decreased because the allelic frequency of B which is dominant increased. Was the decrease in the frequency of bb individuals between successive generations always the same? Why or why not?
Yes it could be eliminated but it woul take a really long time. Since there are heterozygous pair, it may never go away but with time the dominant allele will take over and then there will be less and less of the recessive allele. Most naturally occurring selective pressures do not eliminate reproduction individuals. Instead, their reproductive capacity is reduced by a small propo your results differ if there was only 20% negative selection pressure rather

Table 7 Question 1 How does the number of immigrants effect the changes in frequencies? Table 7 Question 2 In the population 2, the B allele increased in the population while the allele decreased with time in population 1. How does the differences in allelic frequencies between the two populations effect the changes in frequencies? As the b allele decreased in population 1, the B allele frequency increased with time. In population 2, as the b allele increased, the B allelic frequency decreased. Generation
