For each of the seven characters Medel studied,he found the same 3:1 ratio of plants expressing the contrasting traits in the f2 generation.

Mendel saw purple flowers in the F generation but both purple and white flowers in the F How did this help him see that traits are inherited as discrete units?
Because the traits weren't blended resulting in pink flowers. They were still purple and white.
A palnt with purple flowers is allowed to self pollinate generation after generation it produces purple flowers this is an example of?
true breeding!
What was the main experiments Gregor Mendel carried out?
In mendels first experiments, he crossed pea plants to study seven different characteristics. For example he crossed plants that had purple flowers with plants that had whit flowers, the offsprings from such a cross are called first- generation plants. All of his first generation plants had purple flowers. One trait was always present in the first generation , and the other trait seemed to disappear. Mendel chose to call the trait that appeared the dominant trait. Because the other trait seemed to fade into the background, Mendel called it recessive trait.
What did Gregor Mendel study to develop the rules for genetic traits?
Around 1857, Gregor Mendel began breeding green peas to study inheritance. Although heredity was still unknown at the time, Mendel was curious about the subject. Mendel worked with green peas because they were simple to test, produced large numbers of offspring, and had different variety of traits. Mendel discovered that when he bred two true-breeding peas: one purple and one white (a purple flower's offspring will always turn out purple) produced offspring of purple flowers (why was it only purple and not white?) because the trait for a purple color for peas is more dominant. Then he decides to breed those new purple flowers. Mendel found a 3 to 1 ratio of purple and white flowers. This led to two laws from Mendel: the law of segregation and the law of independent assortment.He studied the effects genetics had on the colors of the flowers of a plant.
What generation did Mendel get when he crossed the plants that produced the F1 generation?
100% percent of the plants expressed the dominate trait ........................................................................................ what do u get when u mix purple with purple you get 100% purple :) simple peace of cake !

What was the first generation offspring in Mendel's experiment?
3 purple flowers and 1 white flower the ratio is 3:1 ur welcome! hahaha

Mendel found purple flowers in the f1 generation both prple and white flowers in the f1 generation how did this help him see that traits are inherited as discrete units?
Because he grasped that there had to be an independant "factor" as he called genes and that even if they don't always manifest they are still there and intact.

What kind of trait seems to disappear in the first generation?
all flowers are purple
A plant with purple flowers is allowed to self-pollinate Generation after generation it produces purple flowers This is an example of?
Not necessarily. Many plants now days have been hybridized and will eventually revert to their 'orginal' colors.
What pea attributes did Mendel use?
Mendel crossbred -tall & dwarf pea plants, -green & yellow peas, -purple & white flowers, -wrinkled & smooth peas. And a few other traits.
What was the first generation of offspring in Mendels experiment?
The first generation of offspring from a cross is called the F1 generation.
Why did Mendel test one trait at a time?
Mendel tested one trait at a time so he would be able to eliminate variables. The purpose of his experiment in general was to determine the trends and patterns in inheritance, and so he had be sure he studying only one variable at a time, to understand it well. Specifically, he examined one trait at a time with self-pollinating pea plants, of which there were only two color varieties: purple and white. Before now, there was no chance of white flower's seed having previously been fertilized by a purple flower. He also chose to use peas because they spawn a new generation quickly and produce a large number of offspring. So during the first generation of his pure purple flower and pure white flower crossing, all of the offspring produced purple flowers. Because his subjects were chosen only for the reason of color, and did not differ in other ways, he knew, what would later become known as, the purple-color allele was dominant. It was previously believed that the two colors would "blend" together, producing a pale purple color. So it would make sense that the trait for producing a white flower was lost, and that the flowers would be purple from now on, right? When the this generation self-fertilized, however, there was 3:1 ratio of offspring. 3 purple flowers and 1 white flower. Mendel now had a basis for determining the law of segregation. Later, after performing other various two-option-single-trait experiments such as seed color and wrinkled vs. smooth, he discovered traits were inherited singly, and thus the law of independent assortment was born. Mendel's experiments gave in beautifully to ratios of inherited traits and the ability to determine what traits the offspring would possess as more traits were mixed. If he had tested multiple traits at one time, even unintentionally, his results could have been skewed and even meaningless.
