A student proposes that left-handedness is a recessive trait that is therefore hidden in much of the human population. A survey

of 36 students finds that 27 (0.75) are right-handed and 9 (0.25) are left-handed. Using the Hardy-Weinberg equation, what would the expected genotype and allele frequencies be in this theoretical population?

Answer:

0.25 right-handed homozygous, 0.50 heterozygous, and 0.25 recessive homozygous for a 0.5 allele frequency for each allele

Explanation:

In the Hardy-Weinberg equilibrium equation is ( p²+2pq+q²=1 ),

  • the term 2pq represents the genotype frequency of heterozygotes (Aa) in a population in equilibrium.
  • the term p² represents the frequency of dominant homozygotes (AA) and
  • the term q² represents the frequency of recessive homozygotes (aa).

Which pathway represents the most common sequence of information flow through a neuron?
love history [14]

Answer:c. Dendrite → cell body → axon hillock → axon

Explanation:a neuron has many cytoplasmic extensions called dendrites.the dentrites enter into the cell body at one end . the cell body also leads to axon at the other end, which extends toward another dentrite.axon hillock connect the axon to the cell body.

Impulses are usually transmitted along the neuron in one direction.

From the dendrites to the cell body,to the axon hillock and then to the axon.
