Gregor Mendel cross-pollinated pea plants by manually transferring pollen from the stamen of one pea plant to the pistil of another pea plant. He carefully removed the anthers from the first plant to prevent self-pollination and then applied the pollen to the stigma of the second plant. This process allowed Mendel to control the genetic makeup of the offspring and study the inheritance patterns of specific traits in pea plants.
Mendel used pea pod plants for his early experiments. See http://www.mnsu.edu/emuseum/information/biography/klmno/mendel_gregor.html
Gregor Mendel used pea plants in his experiments to study heredity
maybe he was lucky and he did so without knowing the reason but today we know the pea plant is 2n=14. so it has 7 pairs of chromosomes. if mendel had studied 8 traits for example, then at least 2 of them would've been on the same chromosome and he couldn't have used its mathematical laws of independence because then at least 2 chromosomes were linked.
pea plants
i believe his results were that after cross pollinating to non-purebred pea plants, the offspring were all tall like the female,and when he crossed the other two, he received three tall pea plants and one short
he used plants that were NOT true breeding!
he used plants that were NOT true breeding!
He pollinated the plants himself and in the process he mixed the pollen from pea plants that had different colored to see what the end result would be (I got this all from a textbook I swear)

The terms Mendel used to describe the heterozygous pea plant was the hybrid term....i hope that helped
He cross-pollinated plants
Gregor Mendel developed the model of heredity that now bears his name by experiments on various charactersitics of pea plants: height (tall vs. Short); seed color (yellow vs. Green); seat coat (smooth vs. wrinkled), etc. The following explanation uses the tall/short trait. The other traits Mendel studied can be substituted for tall and short.Mendel started out with plants that "bred true". That is, when tall plants were self-pollinated (or cross-pollinated with others like them), plants in following generations were all tall; when the short plants were self-pollinated (or cross- pollinated with others like them) the plants in following generations were all short.Mendel found that if true breeding Tall [T] plants are crossed (bred) with true breeding short [t] plants, all the next generation of plants, called F1, are all tall.Next, he showed that self-pollinated F1 plants (or cross- pollinated with other F1 plants) produce an F2 generation with 3/4 of the plants tall and 1/4 short.A. 1/4 of the F2 generation are short plants, which produce only short plants in the F3 generation, if they are self- pollinated (or crossed with other short F2 plants;) these F2 plants breed true.B, 1/4 of the F2 generation (1/3 of the tall plants) are tall plants that produce only tall plants in the F3 generation, if they are self-pollinated; these tall F2 plants breed true.C. 1/2 of the F2 generation (2/3 of the tall plants) are tall plants that produce 1/4 short plants and 3/4 tall plants in the next [F3] generation, if they are self-pollinated. This is the same proportion of tall to short that F1 plants produce.

Mendel found that every fourth plant had white flowers when he allowed the first generation to self-pollinate. Gregor Mendel was a scientist who lived from 1822 to 1884.hyuyt6yt8
Gregor Mendel's pea plant experiment allowed him great control, as pea plants can self-pollinate or cross-pollinate, and he was able to pollinate them at will. He studied the characteristics of each plant he would cross-pollinate, perform the pollination and plant the resulting seeds, then study the characteristics of the resulting plants.
Gregor Mendel did his experiments because he was looking to see how genetics and heredity worked. He used pea plants because they bred true. He found that the taller plants all produced tall plants if they were self pollinated. If short plants were used and were cross pollinated, they would all be short.
Gregor Mendel took two true-breeding plants with contrasting traits and cross-pollinated them, producing offspring with genes for both characteristics. He used selective breeding.
