allowed plants to self-pollinate for several generations
its allowing plants to self-pollinate for several generations.
I dont know but i have a kid
Mendel collected seedss from his pea plants, carefully recording the characteristics of the plants grew from the seeds obtained from the purple-flowering plants, but he noticed he noticed that some white-flowering plants. And when experimenting with the characteristic of plant height, he observed that while some tall plants grew from seeds obtained from tall plants. some short plants also grew from seeds obtained from tall plants.
Mendel did his studies on pea pod plants.
explain how Gre gor Mendell obtained pureline strans of pea plants for use in his studies of genetics.
Mendel selected true breeding tall (TT) and dwarf (tt) pea plants. Then, he crossed these two plants. The seeds formed after fertilization were grown and these plants that were formed represent the first filial or F1 generation. All the F1 plants obtained were tall.Then, Mendel self-pollinated the F1 plants and observed that all plants obtained in the F2 generation were not tall. Instead, one-fourth of the F2 plants were short.From this experiment, Mendel concluded that the F1 tall plants were not true breeding. They were carrying traits of both short height and tall height. They appeared tall only because the tall trait is dominant over the dwarf trait.
Gregor Mendel
Selfing, self fertilization until the offspring showed not deviation from the parental stock.
Cross-Pollinate
Whenever Mendel performed a cross with pea plants, he carefully categorized and counted the many offspring. Every time Mendel repeated a particular cross, obtained similar results. For example, whenever Mendel crossed two plants that were hybrid for stem height (Tt), about three fourths of the resulting plants were tall and about one fourth were short. Mendel realized that the principles of probability could be used to explain the results of genetic crosses.
out of total 1064 plants in f2 generation,787 plants were tall & 277 plants were dwarf.Means 3:1 ratio was obtained.

He studied dominant and recessive genes. He studied pea plants and the traits that they obtained from previous generations.
Gregor Mendel
Gregor Mendel used pea plants to study heredity.
Mendel removed the anthers of one of the plants.
