a) allelic frequencies in conglomerate population using formula Delta Pc = m (PD-Pr)
Delata Pc change in allelic frequency in conglomerate population
M= proportion of migrates in conglomerate population
PD= allele frequency in donar population
Pr=allele frequency in recipient population
For allele HbA the frequencies in conglomerate population are
M= proportion of migrates in conglomerate population = 550/10,000= 0.055%
PD= allele frequency in donar population= 0.9
Pr= allele frequency in recipient population= 0.99
Therefore, change in allelic frequency of allele Delta Pc = m (PD-Pr)
= 0.055(0.9-0.99)
= -0.00495
HbA allele found in conglomerate population is at frequency of 0.99- 0.00495=0.98505
For allele Hbs the frequencies in conglomerate population are
M= proportion of migrates in conglomerate population= 0.055
PD= allele frequency in donar population= 0.1
Pr= allele frequency in recipient population= 0.01
Therefore, change in allelic frequency of allele Delta Pc = m (PD-Pr)
= 0.055(0.1-0.01) = 0.00495
Hbs allele found in conglomerate population is at frequency of 0.01+ 0.00495= 0.01495
Delta Pc = m (PD-Pr)
Delata Pc change in allelic frequency in conglomerate population
M= proportion of migrates in conglomerate population
PD= allele frequency in donar population
Pr=allele frequency in recipient population
For allele HbA the frequencies in conglomerate population are
M= proportion of migrates in conglomerate population = 550/10,000= 0.055%
PD= allele frequency in donar population= 0.9
Pr= allele frequency in recipient population= 0.99
Therefore, change in allelic frequency of allele Delta Pc = m (PD-Pr)
= 0.055(0.9-0.99)
= -0.00495
HbA allele found in conglomerate population is at frequency of 0.99- 0.00495=0.98505
For allele Hbs the frequencies in conglomerate population are
M= proportion of migrates in conglomerate population= 0.055
PD= allele frequency in donar population= 0.1
Pr= allele frequency in recipient population= 0.01
Therefore, change in allelic frequency of allele Delta Pc = m (PD-Pr)
= 0.055(0.1-0.01) = 0.00495
Hbs allele found in conglomerate population is at frequency of 0.01+ 0.00495= 0.01495
b) Genotypic frequencies after migration
Frequency of HbA (p)=0.98505
Frequency of Hbs (q)= 0.01495
Frequency of dominant allele = p2 = 0.9703
Frequency of recipient allele = q2 = 0.00022
Frequency of heterozygote= 2pq = 0.2945
c) frequencies in next generation would not change for the population which already achieved the heardyweinburg equilibrium. There fore
Genotypic frequencies in next generation after migration are as fallows
Frequency of HbA (p)=0.98505
Frequency of Hbs (q)= 0.01495
Frequency of dominant allele = p2 = 0.9703
Frequency of recipient allele = q2 = 0.00022
Frequency of heterozygote= 2pq = 0.2945
