Chapter 7 - Diybryd/Gregor Mendal Flashcards
In the case of the Pea experiment, what ratio did Gregor Mendel find in his studies when crossing a homozygous dominant and homozygous recessive?
He found that every offspring and every possible offspring only had the dominant phenotype.
In the second generation (all hetrozygous) of comparing round (W), wrinkly (w), yellow coloured (G) and green coloured (g). What was all the possible combinations and their ratios?
Round/Green: 3/16 WWgg or Wwgg
Round/Yellow: 9/16 WwGg, WWGg, WwGG or WWGG
Wrinkly/Green: 1/16 wwgg
Wrinkly/Yellow: 3/16 wwGg or wwGG
In the second generation (all hetrozygous) of comparing round (W), wrinkly (w), yellow coloured (G) and green coloured (g). What was all the possible combinations and their ratios?
Round/Green: 3/16 WWgg or Wwgg
Round/Yellow: 9/16 WwGg, WWGg, WwGG or WWGG
Wrinkly/Green: 1/16 wwgg
Wrinkly/Yellow: 3/16 wwGg or wwGG
What rules did Gregor Mendel establish?
The rules of heredity.
What is Gregor Mendel most famous for?
The pea plant experiment(s) 1856 -1863
Like many legendary artists and scientists, Gregor Johann Mendel’s work was not recognized or used until after he (____).
Died
His work was excepted and used decades later. Since then his studies have became known as Mendel’s Laws and he is now considered the “father of modern genetics”
Before becoming a monk or even going to school. Where did Gregor Mendel live and to what age?
He lived on a farm and he lived there until age 11.
With all of Mendel’s observations. What two points do they come down too?
- Principle of segregation
2. Principle of independent assortment
At the time Gregor Mendel was alive, what was the common belief when it came to genetics?
That a trait blended as it passed through generations.
There are three other findings that Gregor Mendel had, what is the first one?
That each trait is decided by “units” (now referred to as genes) that is passed on from generation to generation.
There are three other findings that Gregor Mendel had, what is the second one?
That the offspring inherits one “unit” from their parent.
There are three other findings that Gregor Mendel had, what is the third one?
That you may not be able to see the trait in a person, but the trait can still be passed on.
