How did Gregor Mendel develop genetics?
For Gregor Mendel, pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow, could be bred rapidly, and had several observable characteristics, like petal color and pea color.
May 8, 2019 · Mendelian inheritance is a term arising from the singular work of the 19th-century scientist and Austrian monk Gregor Mendel. His experiments on pea plants highlighted the mechanisms of inheritance in organisms that reproduce sexually and led to the laws of segregation and independent assortment.
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...
Mendel followed the inheritance of 7 traits in pea plants, and each trait had 2 forms. He identified pure-breeding pea plants that consistently showed 1 form of a trait after generations of self-pollination. Mendel then crossed these pure-breeding lines of plants and recorded the traits of the hybrid progeny.
By experimenting with true-breeding pea plants, Mendel avoided the appearance of unexpected traits in offspring that might occur if the plants were not true-breeding. The garden pea also grows to maturity within one season, meaning that several generations could be evaluated over a relatively short time.
Mendel’s seminal work was accomplished using the garden pea, Pisum sativum, to study inheritance. This species naturally self-fertilizes, meaning that pollen encounters ova within the same flower. The flower petals remain sealed tightly until pollination is completed to prevent the pollination of other plants.
Apr 22, 2013 · Gregor Mendel describes his experiments with peas showing that heredity is transmitted in discrete units. From earliest time, people noticed the resemblance between parents and offspring, among animals and plants as well as in human families.
