Fire is a natural part of the grassland ecosystem and helps maintain its health and vigor.

erik [133]
<span>I believe the answer is REM alpha sleep. Sleep is a complex  biological process that accompany various physiological changes. Normal sleep is usually classified into non-rapid movement (NRE) and rapid eye movement sleep (REM), where the stages of NREM are followed by REM sleep. REM alpha sleep is a stage of REM that is associated with unique brain wave pattern such that during REM sleep a sleepers brain waves demonstrate characteristics similar to a walking sleep, a combination of alpha, beta and desynchronous waves.</span>

In a hardy-weinberg population with two alleles, a and a, that are in equilibrium, the frequency of allele a is 0.2. what is the
Allushta [10]
The Hardy-Weinberg equation is as follows:
( {p + q})^{2}  = 1
{p}^{2}  +2pq +   {q}^{2}  = 1
Where:
(convert all % to decimals)

p= homozygous dominant
q= homozygous recessive
pq= heterozygous

While you did not specify whether the 0.2 frequency was for dominant or recessive, we can still figure out the answer.

Using the 1st equation, we can solve for the other dominant/recessive frequency:

1-0.2=0.8

Meaning that:

p= 0.8 & q=0.2

If the heterozygouz frequency is 2pq, then it becomes a simple "plug & chug" sort of approach.

2(0.8)(0.2)= 2(0.16)= 0.32

So, the heterozygous frequency would be:
0.32

Hope this helps!
