The rate for a recessive allele to decline to half its initial frequency will depend on the presence of selective evolutionary forces and random mating.
<h3>What is recessive allele frequency?</h3>
The recessive allele frequency refers to the initial frequency of a recessive allele in a population, which is masked in heterozygous individuals.
The recessive allele frequency depends on the adaptive fitness of this gene variant, the presence of selective forces and random mating, that facet its rate of change.
In conclusion, the rate for a recessive allele to decline to half its initial frequency will depend on the presence of selective evolutionary forces and random mating.

Arthritis. Common symptoms of arthritis are: joint inflammation & swelling, and stiffness
Answer:
Frequency of B allele is 0.6681
Explanation:
If p represents the frequency of dominant allele and q represents the frequency of recessive allele, according to Hardy-Weinberg equilibrium:
p + q = 1
p² + 2pq + q² = 1
where p² = frequency of homozygous dominant genotype
q² = frequency of homozygous recessive genotype
2pq = frequency of heterozygous genotype
Given that number of recessive chestnut horse = 28
Total horses = 226 + 28 = 254
frequency of b² genotype = 28/254 = 0.1102
frequency of recessive b allele = √0.1102 = 0.3319
So, frequency of B allele =
1 - 0.3319 = 0.6681
Hence frequency of B allele is 0.6681
