BLUE FAMILY




The chart above shows the family generation of a small community in Kentucky.  They had a weird skin pigment that changed their skin blue.  It was started to spread because many people had babies with their own cousins.  Its kinda gross but the gene was passed down from generation to generation.  It was a dominate gene early in the generation because it was a small community and most family members had kids together.  As the town started getting bigger due to mining the blue skin started to fade away.  Many doctors didn't know why their skin was blue but it was very interesting.  This was a very interesting article, their was so much information on this generation of blue people.

TASTE STRIPS-Genetics



This chart shows a little part of my family generation.  We were given these strips that you put on your tongue to see if you can taste it or not taste it.  My mom wasn't able to taste it or her parents or my little sister could not taste the strips.  On the other had my dad could taste it.  I could also taste it and so could my older brother and sister.  The squares stand for boys and the circles stand for girls.  If the shape is colored in the person could taste the strip of paper.  This all has to do with genetics if you can taste it, its a dominate gene in my family.  This little experiment was very interesting and I liked watching my dad and older brother and sister taste it because they made a funny face.  This is truly a dominate gene in my family because more people could taste the strip.

Mouth CANCER

        Mouth cancer is a very harmful cancer, there were about 35,000 people in the United States who got oral cancer in the years of 2008.  Cancer is defined as the uncontrollable growth of cells that invade and cause damage to the surrounding tissue.  Men have a higher chance of getting mouth cancer than females.  Males or smoke or use smokeless tobacco, or also know has snuff have a way higher risk of getting oral cancer.
        How can you tell that you have or are getting close to mouth cancer?  Sores is one symptom that you might have oral cancer.  Oral cancer can occur any where in the mouth, like on your tongue, gums, lips, floor of your mouth, top of your mouth, or in your throat.  Bleeding in your mouth is another way you can tell that you have oral cancer.  Smoking and chewing will make you have a higher risk of getting mouth cancer.  Genetics is another way that you can receive this horrible cancer.  If people in your family tree has had oral cancer, their is a possibility that you can get it.  Mouth cancer occurs when cells on your lips or in your mouth develop changes in their DNA, this is called mutations.  These mutations allow cancer cells to grow when the healthy cells die out.  Mouth cancer cells can grow into tumors.  Once the cancer is growing it can spread through out or body, which can cause death.  Oral cancer is very harmful and you truly have a higher risk if you smoke or chew tobacco.

STEM CELLS

-What are stem cells?
Stem cells are many types of cells that divide into many other types of cells. It matters if the cells are in multipotent or pluripotent, the both are repairing systems, that can divide as many times as they want.


-What are the different types of stem cells, and where do they come from?
The different types of stem cell are multipotent or pluripotent, and they come from many other cells like, red blood cells, muscle cells, or brain cells. The stem cells mainly come from human embryos. 
-Pluripotent stem cells can give rise to any type of cell in the body except those needed to support and develop a fetus in the womb.
-Stem cells that can give rise only to a small number of different cell types are called multipotent.



-What is the potential for new medical treatments using stem cells?
The purpose for using stem cells as medical treatments is because if some one is healthy, they can take that stem cell out.  They can freeze it over time and inject it in some one else who needs it.  They are mainly injected to the immune system to help people get better.
