The correct answer is: b. conscious neural control

Neural control of digestive tract is unconscious achieved via the autonomic nervous system.

Local nervous system of the digestive system is called the enteric or intrinsic nervous system. The major components of this nervous system are two networks or plexuses of neurons:

• The myenteric plexus – controls digestive tract motility

• The submucous plexus - regulates gastrointestinal blood flow and controls epithelial cell function.

Black coat color in horses is conferred by the presence of a dominant B allele. Chestnut horses are genotype bb. A population of
AysviL [449]

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
