Rh-positive individuals have the Rh antigen on their red blood cells, while Rh-negative individuals do not. If the Rh-positive phenotype is produced by a dominant gene (A), and the Rh-negative phenotype is due to its recessive allele

(a). what is the frequency of the Rh-positive allele if 84% of a population is Rh-positive?

Frequency of the Rh-positive allele

Explanation:

Given-

A represents the dominant gene i.e Rh-positive

a represents the recessive gene i.e Rh-negative

It is given that 84% of a population is Rh-positive. This means that 84% of a population will have genotype either Aa or AA

Now as per Hardy Weinberg's equation -

 is the frequency of Aa or AA genotype

is the frequency of aa genotype

Frequency of recessive allele

As per first equation of HW equilibrium -

Substituting the value of q in above equation , we get

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
