After studying the textbook reading assignment, pick a specific organ or structure from the systems covered this week. Describe how its form supports its function. Discuss the relationship of form and function in general and suggest ways that particular organs or structures might be improved to better fit their functions. Tell us about the organ system that it is part of, and describe some specific ways that system interacts with at least one other organ system.

Family History Taking/Pedigree Construction
Assignment
Mary Jones Fictitious Family History
Mary Jones, age 47, is presenting to the family practice office as
a new patient due to a change in her insurance coverage. Her
history is as follows; in the past she has had 2 normal screening
mammograms (last one performed 14 months ago) and all past pap
smears have been negative (the last one performed 13 months ago).
She has had two full term pregnancies and one documented
miscarriage. She is currently an administrator in a community
hospital. She exercises regularly and has no chronic health
conditions. She has been married for 13 years.
For this assignment you will need to construct Mary Jones’s family
pedigree. In order to do this, you will first need to take a family
history. Please provide a list of detailed questions you would ask
Mary to construct her family pedigree. Once you have completed your
questions you will then use the information below to construct the
pedigree.
The following bulleted text contains information about Mary’s
family members (you can choose / make up the ancestral backgrounds
of the different family branches)
• Mary’s 1st child: Cathy Baker, age 31, healthy, has a son and
daughter ages 10 and 4. Cathy lives out of state, infrequently
communicates with her mother, was adopted and raised by her
paternal grandparents. There is no information about Cathy's
biological father's health other than he is alive as are his
parents. Nothing else is known about his family history.
• Mary’s Twin son and daughter, age 8, o Son, Derrick - (twin A)
has Down syndrome, is healthy (used to have problems with ear
infections but this has resolved), no structural heart anomalies,
wears glasses, is mainstreamed in 2nd grade classes with full time
teacher aide, receives speech services in school o Daughter, Tammie
- (twin B) healthy, in 2nd grade, good student
• Miscarriage was two years prior to delivery of the twins. The
miscarriage occurred during the 1st trimester. Gender is unknown.
No testing was performed on fetal tissue.
• Husband, David Jones, is 50 years old and healthy. He does not
have children from previous relationships.
• Mary has no brothers or sisters.
• Her mother, Martha Stewart, is 70 years old, has insulin
dependent diabetes, started taking insulin in early 50s, is obese,
and on medications for high blood pressure o Her mother had 5
siblings - 2 are still living: Sister, Hannah, died at age 8
years from pneumonia Sister, Susan, died in her mid 70s from
complications of diabetes. She had 1 son who is in his 50's,
apparently healthy and he has 4 adult children - health status and
number of offspring unknown Brother, Bill Junior, died at age 3
from pneumonia Living sister; Debbie, is in her late 60s, is also
obese and takes insulin injections. She has 4 children: 3 boys and
1 girl - health status and number of children unknown Living
brother; Mike, is in his early 60's, is on dialysis, is an
alcoholic, has two sons - health status and number of children
unknown (birth order: Hannah, Susan, Martha, Bill, Debbie,
Mike)
• Her father, Bill Stewart, died last year at age 69, COD - liver
failure, was also said to have an enlarged heart, rarely drank
alcohol, was slender in build, was on medication for arthritis in
the hips and knees. O Bill's only brother, David, is 67 years old,
and has arthritis. He has one son who is healthy and he has 2
sons.
• Mary’s Maternal grandmother, died in her 60's due to female
cancer
• Mary’s Maternal grandfather, died in his 60's, cirrhosis of the
liver, was an alcoholic
• Mary’s Paternal grandmother died in her 80's, heart failure
• Mary’s Paternal grandfather, died in his late 50's, lung cancer,
heavy smoker
I will rate it with thumbs up.
I need answers.

3. In mice, genes for albinism (a), chronic inflammation (i), and reduced sense of smell (r) are linked. You initially crossed a mouse that is homozygous dominant for all three traits with a mouse that is homozygous recessive for all three traits. You then crossed several of the resulting F1 offspring to mice that are homozygous recessive for all three traits. You observe the following phenotypes in the offspring:
colored, healthy, normal smell sense |
41 |
albino, chronically inflamed, reduced smell sense |
45 |
colored, chronically inflamed, reduced smell sense |
11 |
albino, healthy, normal smell sense |
12 |
colored, healthy, reduced smell sense |
2 |
albino, chronically inflamed, normal smell sense |
3 |
colored, chronically inflamed, normal smell sense |
14 |
albino, healthy, reduced smell sense |

a. (3 points) Diagram a map between these three genes and calculate the map distances between the genes.
b. (3 points) Calculate the coefficient of coincidence and the interference values for double crossovers amongst these genes.
c. (2 points) Using the interference value calculated in part (b), how many double recombinant F2 progeny will you observe if you continue to breed your F1 mice until you have 200 total offspring?
d. (2 points) If a fourth gene (z) exhibits 50% recombination with gene i, 36% recombination with gene a and 50% recombination with gene r, is this gene on the same chromosome or a separate chromosome? If gene z is on the same chromosome as the other three genes, indicate its location by copying and modifying your genetic map from part (a).
Please for part c and d explain it with detail because i have more problem with part c and d , thank you

I got to the part in bold and I have no idea where to go from here.
Step 1:Find the pair with the smallest distance.
Step 2:Join them in one group and draw those branches.
Step 3:Compute average distance between this group and all other taxa one-by-one and create new table with those values.
Step 4:Repeat Steps 1 to 3 using the new distance matrix.

Based on above data, find the first two characters with the shortest distance and draw those branches with the respective distances on the branches below according to the example given in class or online. This should be your first two branch tips.
C and D is the pair with the shortest distance as it is 2 units. A sub tree will be drawn with the branch point half way between the two given units. Each branch is 1 unit as this is 2 units divided equally and each point is 1 unit away from the center node.
Recalculate distances based on the combination of the last characters. This first table has been partially filled out for you. Determine and enter the missing values. (You need not fill out the boxes above the dashes as they are mirror values to the below-dash values.)

It is 3pm and you are hungry, but it is too early for dinner so you decide to eat a Snickers bar. Since a Snickers has sugar, fat and protein many of the metabolic pathways you have learned about this semester kick into gear.
a. Explain (words or diagram or combo of both) how the fat from the candy is processed, starting with absorption in the digestive system and ending with storage in adipose cells.
b. Apply the redundancy = efficiency theme specifically between glucose metabolism and protein metabolism from the ingested candy bar. You may write sentences, draw diagrams, make a bulleted list, etc. or any combo.
