Answer the following after setting the assortative mating setting to 1 and running the simulation for greater than 100 generations.
After greater than 100 generations what is the new allele frequencies?
Did the assortative mating favor either allele? .
Which other population parameter was affected by the change in assortative mating?
Which mechanism of evolution was illustrated by the change in assortative mating?
Answer the following after changing the Genotype Relative Fitness for white koi to 0.5. Continue the simulation through 100 generations.
What are the allele frequencies after 100 generations?
What are the genotypic frequencies after 100 generations?
Why is the frequency of q not equal to 0.0, even if the frequency of the white koi is zero?
Which type of mechanism of evolution is demonstrated by the reduced genotype relative fitness experiment?
Which change to the genotype relative fitness parameters would simulate a natural selection pattern of stabilizing selection?

Describe in words how fatty acids are released in the body AND how fatty acids arrive at the appropriate cellular location for use (no structures). Beginning from this point, provide the details in words (names of structures, enzymes, cofactors, etc.) for one round of fatty acid degradation. Include the tissue and cellular locations for each part of the process of harvesting fatty acids for energy. What pathway does the primary product enter next? Provide details in words (names of structures, enzymes, cofactors, etc.) for the reaction steps where carbon leaves the pathway. You don't have to go over the entire pathway – only the steps where carbon is lost.

A 30 y male was delivered to andrology department for
medical evaluation due to ineffective sexual competency. His
physical examination and interview with the specialized physician
revealed some other symptoms that were related to wounds that won’t
heal, unexplained weight loss, hair loss, lack of alertness and
sometimes diarrhea. These symptoms were seen in the last 6 months
only and nothing seen before.
Semen analysis and other tests were prescribed and the
results were:
Semen analysis
Days of abstinence: 3 days
Time of collection: 9:30 am
Time of receipt: 9:45 am
Liquifaction time: 30 min
Volume: 4ml
Viscosity: normal
pH: 8.5
Sperm concentration: 12 million/ml
Sperm motility: marked decreased motility
Morphology: more than 50% normal forms
Spermatids and WBCs: less than 1 million/ml
Other tests
Fructose level was in normal range
Viability testing showed that most sperm are
viable
Low serum testosterone
Discuss these results, what is the expected case,
mention any confirmatory tests if required
Note : My doctor sad that it was related to zinc deficiency , how i
can explain that .
