In a population there are 400 AA, 400 Aa, and 200 aa individuals. (a) Calculate allele frequencies. f(A) = 0.6 if(a) = 0.4 (b) Calculate predicted HWE genotype frequencies. f(AA) = 0.36 f(Aa) = 0.48 f(aa) = 0.16 (c) Is this population in Hardy-Weinberg equilibrium? Provide a chi-square value and p-value, and your statistical and biological decision. chi-square value = 15.23 X (round up your answer nearest 100th) 0.1 x > p-value > 0.05 IX Statistical decision: reject (reject / fail to reject) Biological decision: This population is not (is / is not) in HWE.
Based on the chi-square value and p-value, the statistical decision is to reject the null hypothesis that the population is in Hardy-Weinberg equilibrium. The biological decision is that this population is not in Hardy-Weinberg equilibrium.
Chi-square value: 15.23
P-value: 0.05
Statistical decision: Reject
Biological decision: This population is not in HWE.
Step 1: Calculate allele frequencies
To calculate allele frequencies, we need to know the total number of alleles in the population. In this case, there are 400 AA, 400 Aa, and 200 aa individuals, for a total of 1200 alleles. Since there are two alleles (A and a), we can calculate the frequency of each allele by dividing the total number of each allele by the total number of alleles:
f(A) = 400/1200 = 0.6
f(a) = 800/1200 = 0.4
Step 2: Calculate predicted HWE genotype frequencies
Using the allele frequencies, we can calculate the predicted HWE genotype frequencies using the equation:
f(AA) = f(A)*f(A) = 0.6*0.6 = 0.36
f(Aa) = 2*f(A)*f(a) = 2*0.6*0.4 = 0.48
f(aa) = f(a)*f(a) = 0.4*0.4 = 0.16
Step 3: Calculate chi-square value and p-value
The chi-square value is calculated by comparing the observed and expected frequencies of the genotypes in the population. In this case, the observed frequencies are 400 AA, 400 Aa, and 200 aa individuals, while the expected frequencies are 0.36 AA, 0.48 Aa, and 0.16 aa individuals. The chi-square value is then calculated as follows:
chi-square value = 15.23
The p-value is calculated by comparing the chi-square value to a chi-square table with 1 degree of freedom. In this case, the p-value is greater than 0.05.
Step 4: Make a statistical and biological decision
Based on the chi-square value and p-value, the statistical decision is to reject the null hypothesis that the population is in Hardy-Weinberg equilibrium. The biological decision is that this population is not in Hardy-Weinberg equilibrium.

2. Bone
A 68-year-old Asian female presents with mildly achy muscles and joints. The aches seem to “come and go” quite often lasting for several days at a time. Upon examination you take note of a hunch-backed appearance on the patient. An x-ray is performed and showed a significant decrease in bone tissue mass. After further diagnostic testing is performed the patient is diagnosed with Osteoporosis. TAKE NOTE: Osteoblast cells build bone matrix while osteocytes maintain the matrix. Osteoclast cells break down bone matrix and reabsorb the nutrients.
Using your knowledge of the human physiology, which of the following do you predict is a potential cause of the Osteoporosis?
A. Decreased osteoblast activity B. All choices are potential causes
C. Increased osteoclast activity D. Secondary to external factors like drugs/cancers
Osteoporosis causes bone density to decrease due to decreased osteoblast activity, increased osteoclast activity, and external factors like long-term medication. Option B. All choices are potential causes.
What are the factors that promote osteoporosis?
Let us first review what the bone cells are and their functions,
• Osteoprogenitores → in charge of osteocytes production
• Osteocytes → maintain the matrix
• Osteoblasts → Synthesize and secrete osteoid matrix that will later calcify
• Osteoclasts → Phagocytic cells in charge of osseous resorption and bone modulation.
Osteoporosis is a no-symptoms disease -silent- that causes a decrease in the bone mineral and mass density and might change the bone structure.
Osteoporosis weakens the bone until it breaks. So this affection becomes evident when a fracture occurs.
Several factors lead to osteoporosis development. Among them, we can mention,
genetic factors, habits factors (lifestyle),hormonal alterations,drugs/medication
The increased rate of bone resorption is the major mechanism by which osteoporosis occurs. It deteriorates bone structure and decreases bone density.
Bone resorption and deterioration might be caused by
a decrease in osteoblast activity, leading to the decrease in osteoid matrix formation and calcification,an increase in osteoclast activity, enhancing the activity of these phagocytic cells.
Other external factors also increase the probability of developing osteoporosis. Some of them are,
long-term medications (for instance, those used in cancer treatment) excessive alcohol consumption and smokingsedentary lifestylepoor dietAccording to this framework, the potential causes of the Osteoporosis are Decreased osteoblast activity, Increased osteoclast activity, Secondary to external factors like drugs/cancers.
Hence, option B is correct, All choices are potential causes.

Altruistic behavior in animals may be a result of kin selection, a theory maintaining that:
a) genes promote the survival of copies of themselves when behaviors by animals possessing those genes assist other animals that share those genes.
b) aggression within sexes increases the survival and reproduction of the fittest individuals.
c) companionship is advantageous to animals because, in the future, they can recognize those that have helped them and provide help to those individuals.
d) aggression between the sexes increases the survival and reproduction of the fittest individuals.
e) companionship is advantageous to animals because, in the future, they can recognize those that have helped them and request help once again.
Kin selection, which contends that genes are more likely to survive within a population when they result in actions that benefit other animals who share those genes, may be the cause of altruistic behavior in animals.
What is the kin selection theory in animal behavior?According to the kin selection theory, animals are more likely to show altruistic behavior toward their relatives than toward other members of their species. Furthermore, data suggests that the stronger the bond, the greater the degree of altruism.
What does altruistic behavior theory entail?When a person's actions are driven by a desire to help another person for that person's sake rather than their own, that behavior is typically referred to as altruistic. The phrase is used to contrast with being "self-interested" or "selfish."
