A keystone is a organism that helps define the entire ecosystem, and if the species were to disappear from the ecosystem no other species would be able to fill its ecological niche the ecosystem would be forced to radically change allowing new and possibly invasive species to populate the habitat.

In the laboratory, a genetics student crossed flies with normal, long wings to flies with mutant, dumpy wings, which she believe
Marianna [84]

Answer:

a. Chi-Square Value = 0.12

b. Degrees of freedom = 1

c. Reject or fail to reject the hypothesis = fail to reject the hypothesis

Explanation:

<u>Available data:</u>

  • Cross: long wings to flies with mutant, dumpy wings
  • F1) 100% long-winged flies
  • F2)  672 long-winged flies 218 dumpy-winged flies
  • Hypothesis: the dumpy wing is inherited as a recessive trait

Let us name the allele for Long L and the allele for dumpy l

The number of observed individuals:

  • Total number: 890 flies (672 + 218)
  • Long-winged = 672
  • Dump-winged = 218

In the F2 generation, if l was a recessive allele and L a dominant allele, exhibiting complete dominance, we would expect a 3:1 phenotypic ratio.

Cross:          Ll   x   Ll

Gametes)   L   l    L  l

Punnett square)   L     l

                     L    LL    Ll

                      l     lL     ll

F2) 3/4 LL + Ll long-winged individuals

      1/4 ll dump-winged individuals

From this ratio and the total number of individuals in the F2 generation, we can get the expected number of individuals:

4 possible genotypes ------- 890 individuals

3 LL + Ll genotype ------------X = 667.5 long-winged individuals

1 ll genotype ---------------------X = 222.5 dump-winged individuals

 

Chi square = ∑ (O-E)²/E

LL + Ll = (O-E)² /E

LL+ Ll = (672 - 667.5) ² / 667.5

LL + Ll = 0.03

ll= (O-E)²/E        

ll= (218 - 222.5)² / 222.5

ll= 0.09  

  • Chi square= ∑ ((O-E)²/E) = 0.03 + 0.09 = 0.12
  • Freedom Degrees = genotypes - alleles = 3 - 2 = 1
  • Significance level = 0.05    
  • Table value/Critical value = 3.84

0.12 < 3.84 meaning that there is enough evidence to reject the null hypothesis.

Fail to reject the hypothesis.  The genotypes in the population might be in equilibrium H-W. L is the dominant allele, and l is the recessive allele. The dumpy wing is inherited as a recessive trait.
