A fly has two alleles for the color of its eyes. The green allele is recessive, and
is represented by q. The blue allele is dominant, and is represented by p. If 44
of 100 organisms are green, what is p?
Homozygous dominant+ Heterozygous + Homozygous recessive = 1
↓↓↓
p²+ 2pq+q=1
A. 0.66
B. 0.56
C. 0.44
D. 0.34
Answer: D. 0.34
Explanation:
The Hardy-Weinberg Principle is a theory in biology that represents populations of organisms that don't experience any changes in genotypic frequency from generation to generation. These populations must meet the following conditions:
No genetic mutationsCompletely random matingNo gene flowNo selection (natural or artificial)An infinite population sizeIf a population meets these criteria, its genetic and allelic frequencies will remain constant and the population will be in Hardy-Weinberg Equilibrium. However, it is not possible for this to occur in nature, because at least one condition will always be violated in natural populations.
Hardy-Weinberg EquationsThere are two important equations to use when doing problems like this. The first is p + q = 1. It represents the allelic frequency of the population.
p = the frequency of the dominant alleleq = the frequency of the recessive allele
The second equation is p² + 2pq + q² = 1, which shows the predicted frequencies of the three possible genotypes.
44 of our 100 organisms are green, and we know that to be green, they must have a homozygous recessive genotype (gg). That means that the frequency of homozygous recessives (q²) = 44/100 or 0.44. Since we have q², we can just take the square root to find q.
[tex]\sqrt{q^2}[/tex]= [tex]\sqrt{0.44}[/tex]
q = 0.66
Now, we can plug q into our first equation, p + q = 1.
p + 0.663 = 1
p = 0.337, or about 0.34
To make sure these are right, we can plug them into the Hardy-Weinberg equation to check!
p² + 2pq + q² = 1
(0.34)² + 2(0.34)(0.66) + (0.66)² = 1
0.1156 + 0.4488 + 0.4356 = 1
1 = 1

Propose an ecological solution that would protect the tiger species by maintaining the complex interactions within an ecosystem. Provide at least one strength and one limitation to this proposed solution.
Tigers have the ability to coexist with their own predators like brown bears, leopards, etc. In this condition, it is the risk that these predators may threaten the tiger species. Therefore, it is required to construct a special habitat for tigers where they get enough resources without any threat.
What is an Ecosystem?An ecosystem may be defined as a place or area where members of different species live together and interact with one another for the purpose of food, shelter, and space.
The strength of the above solution is that the population of tiger species will be maintained in near future, but the limitation is that here we provide an artificial habitat for the tiger. Now, it depends on them to reside naturally or not.
