In the scientific method, the 5th requirement is control of the experiment. In order to have control over his trials, Mendel could not raise the plants outside where any pollinator could have come along and ruin his carefully crafted experiments.
Probably because it was easy to use and the fact that he had red peas and white peas could help him as markers for his studies on genetics.
mendel worked with pea plants because they were easy to grow.
He studied plants and was a gardener.
The genetic experiments Mendel did with pea plants took him eight years (1856-1863) and he published his results in 1865. During this time, Mendel grew over 10,000 pea plants, keeping track of progeny number and type.
The first generation of of pea plants that Mendel bred were tall.
Mendel did his studies on pea pod plants.
Gregor Mendel used pea plants (Pisum sativum) to study heredity.
Mendel observed the characteristics of pea plants which were passed to new generations of pea plants from the parent plants to reveal the nature of genetic inheritance.
pea plants show very different traits that are easy to tell apart and they grow relatively fast
Gregor Mendel
Pea Plants
Gregor Mendel used pea plants for his hereditary experiments
Smooth yellow pea plants and wrinkly green peas.
