Among a particular population of 100 plants, red flowers are dominant and yellow flowers are recessive. F is the dominant allele and f is the recessive allele.
40 plants are homozygous dominant
44 plants are heterozygous
16 plants are homozygous recessive
Use the Hardy-Weinberg equation to calculate the equilibrium frequencies of each genotype.
Answers
Answer:
The genotype of the homozygous dominant will be FF, and the total number of F alleles will be 40 × 2 = 80.
The genotype of the heterozygous plant types will be Ff. There will be 44 F alleles and 44 f alleles.
The genotype of the homozygous recessive will be ff, and the total number of f alleles will be 16 × 2 = 32.
Now the total number of alleles is 200 [(40 × 2) + 44 + 44 + (16 × 2)].
The frequency T of F allele will be .
The frequency t of f allele will be .
Now the frequency of the genotypes is represented by the equation p2+2pq+q2 = 1.
So, (0.62 × 0.62) + 2(0.62 × 0.38) + (0.38 × 0.38) = 1.Or (0.3844) + (0.4712) + (0.1444) = 1.
So, homozygous dominant frequency is 0.3844;heterozygous dominant frequency is 0.4712; and homozygous recessive frequency is 0.1444.
