Flip-flopping Gene Expression Can Be Advantageous

Summary:One gene for pea pod color generates green pods while a variant of that gene gives rise to the yellow-pod phenotype, a feature that helped Gregor Mendel, the 19th century Austrian priest and scientist, first describe genetic inheritance. However, many modern-day geneticists are focused on the strange ability of some genes to be expressed spontaneously in either of two possible ways.

Mendel and Genetics
Explain the phenomenon being described in the article.pea pods being green or yellow
What is the difference between a genotype and a phenotype?genotype are the letters and phenotype are the physical apperance.
List three things you learned from this article in your own words.Mendel used pea pods for his experiment, he was a priest, and he described genetic inheritence.
What impact would the not understanding genetics have on medicine or agriculture?We would not have some of the medicines and crops that we have now.

Mendel and the mixed up moggie

http://www.newscientist.com/article/mg15220596.000-review--mendel-and-the-mixed-up-moggie.html

Summary: Laura Gould brings home a calico cat named George. George should be female, because everyone knows that only females can be calicos. Even a glance at George's body shaows that he is all male. This unusual discovery her on a search for the genetic anomaly that created her mixed-up moggi.

Explain the phenomenon being described in the article. A cat that is suppose to be a female looks like a male

What is the difference between a genotype and a phenotype? A genotype is the letters, the phenotype is the appearance

List three things you learned from this article in your own words.
1.) Calico cats are all female.
2.) Calico's are red, black, or white
3.) Mendel made a mistake with his experiment

What impact would the not understanding genetics have on medicine or agriculture? you wouldnt be able to know how to make medicines and cure people

Summary: the passage is bassed on when a woman brings home a cat and she thinks because it is a certain color it should be sex linked by that. she goes by the theory that only females can be calicos (black, red and white).it linked between mendles experiment with One crucial revelation being the difference in the method of sex determination between cats and peas (Gregor Mendel's favourite vegetable)

Questions: Explain the phenomenon being described in the article. N?A
What is the difference between a genotype and a phenotype?phenotype is when your determaning 1:1 or 2:4 percent is this or that while genotype is almost the same but u use letters not whole words and u determine 100% or 50%ect.

Sickle-cell mice cured with their own cells

Summary: The article is about mice with the blood disorder Sickle-cell anaemia who were cured with stem cells, but even bigger is the fact that they retrieved the cells from the mouses tail, avoiding the ethically controversial alternative of deriving them from embryos. The problem with using this in human is they can't use viruses to ferry the reprogramming genes into cells because it may cause Cancer later in life.


Explain the phenomenon being described in the article. The phenomenon described in this article is the transformation of tissue cells into stem cells which can be used to treat diseases.


What is the difference between a genotype and a phenotype? Phenotype is physical such as eye color and genotype is the code that tells what the phenotype is such as Tt

List three things you learned from this article in your own words. Stem cells can cure some diseases, tissue cells can be turned into stem cells, their is a way to get stem cells without using embryos


What impact would the not understanding genetics have on medicine or agriculture? Without understanding genetics, genetic diseases would not be identified leaving many infants dead.

Gregor Mendel was very dedicated to his work. He was a monk but on his spare time he worked with plants which led him to genetics. Today he is called the father of genetics. He studied the inheretance of traits in plants.

Mendel and Genetics
Explain the phenomenon being described in the article.talks about Gregor Mendel
What is the difference between a genotype and a phenotype?geno is letters, pheno is looks
List three things you learned from this article in your own words.Gregor was a monk, he loved plants, he was dedicated to his work
What impact would the not understanding genetics have on medicine or agriculture?we wouldn't know our blood types, we wouldn't know how to cure the flu and other diseases or viruses
