Lets see this with example
if you put a red blood cell in a glass of water the red blood cell is in hypotonic solution and that water flows into less concentrated area ( in to the red blood cell ) which eventually will swell and burst.
Another plot is when we put the same red blood cell in a glass full of salty solution which is Heterogeneous solution. In these case the water will move out from the cell to the solution which cause the cell to shrink.

If a population of 1,000 individuals has 160 rr genotypes, assuming simple dominance by the A allele, what is the frequency of t

OverLord2011 [107]

<span>Here square frequency of recessive alleles r^2 = 160/1000 = 0.16

Therefore r = 0.16

Since r + d = 1; d = 1-0.16 = 0.84</span>

A geneticist claims that four species of fruit flies should appear in the ratio

Gemiola [76]

There are sufficient evidences which are of 5% significance level to reject the claim.

<h3>What is chi-square test?</h3>

A statistical test used to compare observed results with expected results is referred to as the chi-square test.

According to the given scenario,

Ratio = 1:3:3:9
Sample size = 2000
Samples = 110, 345, 360, and 1185

To calculate:

Evidence to make conclusion to the geneticist's claim.

Total fruits = 1 + 3 + 3 + 9 = 16

As per the expected number of fruit flies

Each species = 1/16(2000) = 125.3/16(2000) = 375.3/16(2000) = 375.9/16(2000)

Each species = 1125

According to Chi-Square test -

$X^{2} =\epsilon\frac{(O_{i}-E_{i})^{2} }{E_{i}}$

$X^{2}$ = ( 110 - 125)²/125 + ( 345 - 375)²/375 + ( 360 - 375)²/375 + ( 1185 - 1125)²/1125

$X^{2}$ = (15)²/125 + (30)²/375 + (15)²/375 + (60)²/1125

$X^{2}$ = 8

with df = 4 - 1 = 3, and P( x² > 8) = 0.0460.

Thus, with a P-value, it is small, indicates 5% significance level to reject the claim.
