PEDIGREE OF THE ROYAL OR YOUR FAMILY

EXPLAIN THE ROYAL FAMILY cases of hemophyllia in the picture below of the following individuals: Queen Victoria, King Albert, Queen elizabeth II, Prince Charles and Czar Alexei.

Alternatively, CONSTRUCT A PEDIGREE (use the instructions on the file "How to build a pedigree" under UNIT 3 to guide yourself or here) for your family on any of the following traits (remember females are circles, males are squares, dominant phenotype is shaded black, recessive trait is left white, marriage is a joint line between male and female, descendants come down from that joint line):
*Widow's peak
*Cleft chin
*Mid finger hair
*Detached earlobe
*Tongue rolling
*PTC tasting
*Face freckles
*Darwin's ears
*Any other trait that you are aware of or that you would like to track

Answer the following questions after you have found your family's pedigree:
1- Possible genotype of each family member
2- Explanatory hypothesis of you, other family members and your future descendants

P2,P4,P7 - Genographic Project

Go to the genographic project atlas at https://genographic.nationalgeographic.com/genographic/lan/en/atlas.html. Click on the 10,000 B.C. tab so that the migration routes of Y-chromosomes and mitochondrial DNA ancestors show up. Click on different routes that may reflect your ancestors migratory paths or if you found any resemblance with yourself or a family member. Record the haplogroups represented and the description of the traveling endeavors of that genetic marker. Write it in your comment to the blog by answering the following questions.
QUESTION 1: Which haplogroup(s) best describes your ascendant?
QUESTION 2: Describe the haplogroup and its distribution along time? (don’t copy-paste; give a succinct explanation of what you read)
QUESTION 3: How old is that haplogroup?
QUESTION 4: How would you make sure that you actually carry a marker for that haplogroup?
QUESTION 5: How much would it cost that test? (you will need to search this site at “your genetic journey” at https://genographic.nationalgeographic.com/genographic/lan/en/journey.html, and do a Google search such as “checking ancestry DNA”, to compare costs).
QUESTION 6: What is the cost of genetic predisposition tests? (you will need to search the web for something like “checking disease DNA” and look at different companies)

HBIO-P2,P4,P7: Theory vs. Law of Evolution

Comment on the validity of the expression "Theory of Evolution" vs. "Law of Evolution". As a guideline try to discuss this topic too: has there ever been a documented case that contradicts the notion of evolution? Remember to substantiate your opinion with citations from reputable sources.

3 new proposed rules for evolutionary theory - DUE WED FEB 3

This new article in the Scientist does a great job at discussing the latest new rules proposed to append the dogma of evolution (don’t you love debunkers!).

COMMENT ABOUT THE FOLLOWING 3 TOPICS (in parentheses, my comments):

  1. evolvability – (careful where your beef came from ...)
  2. facilitated variation – (call your GNC immediately and prepare for a new and improved version of “what to expect when you are expecting – a grandparents guide”)
  3. multilevel inheritance – (playing with scarier-than-ever eugenics, and freaking out on those ubiquitous plasmids ... I am getting my own carry-on mercury lamp and not taking antibiotics again in my entire life)
http://www.the-scientist.com/2010/1/1/24/1/

What about those plasmids? DUE WED, JAN 27

Antibiotic resistance seems to be on an all-time high.
So, I thought, "I will bring my carry-on Hg-lamp with me!". 
Just to be sure, "I will buy a life-time supply of Canada Dry". One would not want to die as many a Darwinian-like African explorer.
Those two should cover my bases, though maybe get my children a third arm.


Why o why? Blog about my two comments.

How to help yourselves for genetics and mol bio

Make sure you know mendelian crosses (mono and dihybrid), ABO (blood types), names of genetic diseases (X-linked, Y-linked, Huntigton's, etc),  DNA and RNA structure, DNA to RNA to proteins, what the processes do (replication, transcription, translation).

How to help yourselves with Photosynthesis and Respiration

Make yourself a drawing based on the online activity "8.2 closer look" and online activity 8.3 for photosynthesis
For cell respiration do online activity "7.5 closer look" parts 1,2 and 3, and "7.6 + closer look".

Speciation - first come, first serve

Out of these 10 questions, answer ONLY one as first come first serve. This means that 10 people per period should get their reward :-)
1. Of what did Darwin die?
2. Where did he contract it?
3. Name of the disease, scientific and common name.
4. Organism that causes it and vector that carries it.
5. Is there a treatment for it? If so, which one?
6. Who paid for Darwin's trip?
7. How many kids did he leave at home?
8. Scientific name of mosquitos in our area.
9. Of what are these species of mosquitos carriers?
10. What are the statistics for these diseases here in South Florida?

REVIEW QUESTIONS, PROBLEMS AND ESSAYS for MIDTERM

I am giving you a small proportion of my questions at different levels of complexity for you to practice. But, please, don't try the 630 of them! There is no need to do that. These are just for you to see that after doing maybe 20-30 of all of them you should be able to answer any of the others, given that the concepts are not so many. My idea is to showcase for you an assortment of types of questions that you can find. The differences lie not in the concepts but rather in the formats, phrasing and styles, some are theoretical other practical. So, have fun, practice a few and you will be ready. I will take time during class to go over some of the questions.
