By experimenting with pea plant breeding, Mendel developed three principles of inheritance that described the transmission of genetic traits, before anyone knew genes existed. Mendel's insight ...

Oct 11, 2024 · Mendelian inheritance, principles of heredity formulated by Austrian-born botanist, teacher, and Augustinian prelate Gregor Mendel in 1865. These principles form what is known as the system of particulate inheritance by units, or genes. Mendel’s laws include the law of segregation and the law of independent assortment.

The Austrian monk Gregor Mendel experimented with pea plants. He did all of his research in the garden of the monastery where he lived. Gregor Mendel (Figure 5.10.2) was born in 1822. He grew up on his parents’ farm in Austria. He did well in school and became a friar (and later an abbot) at St. Thomas’ Abbey.

Mendel began with pure-breeding pea plants because they always produced progeny with the same characteristics as the parent plant. Mendel cross-bred these pea plants and recorded the traits of their progeny over several generations.
Key principles of genetics were developed from Mendels studies on peas. Mendel found that paired pea traits were either dominant or recessive. When pure-bred parent plants were cross-bred, dominant traits were always seen in the progeny, whereas recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. ...
Mendel proposed that, during reproduction, the inherited factors must separate into reproductive cells. He had observed that allowing hybrid pea plants to self-pollinate resulted in progeny that looked different from their parents. Separation occurs during meiosis when the alleles of each gene segregate into individual reproductive cells (eggs and ...
Mendel carried out his key experiments using the garden pea, Pisum sativum, as a model system. Pea plants make a convenient system for studies of inheritance, and they are still studied by some geneticists today. Useful features of peas include their rapid life cycle and the production of lots and lots of seeds.
