Answer:
f(A1) = 0.9700, f(A2) = 0.0300
Explanation:
According to Hardy-Weinberg equilibrium equation:
p + q = 1
p² + 2pq + q² = 1
where,
p = frequency of dominant allele
q = frequency of recessive allele
p² = frequency of dominant homozygous genotype
2pq = frequency of heterozygous genotype
q² = frequency of recessive homozygous genotype
q² = 9/10000 = 0.0009
A2 = q
= √0.0009 = 0.03
A1 = p
= 1-q
= 1-0.03 = 0.97
Answer:
It is a motor reflex response
Explanation:
This motor reflex is carried out by motor neurons which are located in the Brain and spinal cord. They are of two types, the upper motor neuron and the lower motor neuron. They upper motor neuron connects with the lower motor neuron in the transmission of impulses. Their presynaptic tract is in the cerebral motor area via the corticospinal tract while their post synaptic tract is in muscle fibres. Thus when she hit her legs on the glass, afferent fires was sent to the brain which then sent efferent impulses to the muscle fibers to quickly withdraw the leg due to action of motor neurons.
