What is Hardy-Weinberg principle ?

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

From the Hardy Weinberg Law of Population and Genetics,

We have

x²+2xy+y²=1 and

x+y=1

where

x = frequency of the dominant allele in the population

y = frequency of the recessive allele in the population

x2 = percentage of homozygous dominant individuals

y2 = percentage of homozygous recessive individuals

2xy = percentage of heterozygous individuals

Given 2xy = 0.56

from here, y=0.28/x, (the frequency of the recessive allele ) can be obtained

we need to find 'x'

recall, x+y=1, x=1-y

substituting this gives us

y=0.28/(1-y), which becomes,

y(1-y)=0.28

y²- y + 0.28 (quadratic equation)

Solving this to find 'y' gives two imaginary values of y = 0.44 but ,

There is no imaginary solution  .

Where do scientists obtain adult stem cells?<br> saliva<br> pancreas<br> skin<br> bone marrow
Alex17521 [72]
<span> Embryonic stem cell research is kind of a dead area now since there is no way to control the differentiation. Most research is being done on adult stem cells to help map and control the differentiation process.

Stem-cells from aborted fetuses - The government doesn't sponsor this, if it is done it is by private companies not located in the USA. You could try researching umbilical cord stem cells to be somewhere near your topic. They come from the afterbirth of normal deliveries.

You could do a much easier report by covering cloning of mice through stem-cell technology. It is happening and helping scientists understand diseases. </span>

When bacteria are inoculated into a new sterile nutrient broth, their numbers don’t begin to increase immediately. Instead, ther
Delicious77 [7]

Answer: First, the bacteria will adjust and then it will divide.

Explanation:

Once the bacterial species is put into the cultural medium, there the bacteria present in the medium needs to acclimatize in the medium and then start growing.

There is a lag phase before the log phase because first the bacteria will adjust into the medium and then start dividing.

As we know that the growing medium contains amino acids, growth factors, enzymes and many more things which first needs to be utilized by the bacteria and then it will start dividing.
