In an environment in which insect populations are decreasing, which bird,small insect eater,cactus eater,seed eater,bud,leaf and
Svetllana [295]

Answer:

The population of insect eater birds are decreasing due unavailability of food.

Explanation:

If the population of insects in an ecosystem decreases, so the organisms which feed on them i. e. insect eater birds also decreases and die due to hunger. In an ecosystem, every organism is the food of other organism, if one organism is eliminated or reduced in population, then the other organisms will also be affected.

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.
