Question

B2111 Assignment Lab 5 A population of 20 flowers has 10 individuals homozygous dominant for red color (RR),5 individuals heterozygous (Rr) and 5 individuals homozygous recessive (rr) a) What is the frequency of the R allele? .a3R b) What is the frequency of the r allele? 15 C Ifthe population is in Hardy-Weinberg Equilibrium, how many RR individuals do we expect to have? Show your work. c) d) If the population is in Hardy-Weinberg Equilibrium, how many Rr individuals do we 2pa expect to have? Show your work. If the population is in Hardy-Weinberg Equilibrium, how many rr individuals do we expect to have? Show your work. e) 2 a.

Explanation / Answer

Genotypes

No. of Individuals

Genotypic Frequency

10/20 = 0.5

5/20 = 0.25

Gene Frequency of R in the population

0.5 + [1/2*0.25] = 0.625

Gene frequency of r in the population

0.25 + [1/2*0.25] = 0.375

a) Frequency of R allele – 0.625.

b) Frequency of r allele -0.375

If the population is in Hardy-Weinberg Equilibrium –

0.625 + 0.375 = 1

(0.625 + 0.375)2 = [(0.625)2 + 2*0.625*0.375 + (0.375)2]

c) The no. of RR individuals – (0.625)2 = 0.391

d) The no. of Rr individuals – 2*0.625*0.375 = 0.469

e) The no. of rr individuals – (0.375)2 = 0.141
