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.
Why did Mendel use pea plants?
Mendel studied inheritance in peas (Pisum sativum). He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. … To cross-pollinate peas, pollen from the stamen of 1 plant is transferred to the stigma of another.
How many different pea plants did Mendel Study?
Mendel and his assistants eventually developed 22 varieties of pea plants with combinations of these consistent characteristics. Mendel not only crossed pure-breeding parents, but he also crossed hybrid generations and crossed the hybrid progeny back to both parental lines.
What plant did Mendel research?
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.
What 7 traits did Mendel study in pea plants?
On the next screen, he reveals that there are seven different traits:
- Pea shape (round or wrinkled)
- Pea color (green or yellow)
- Pod shape (constricted or inflated)
- Pod color (green or yellow)
- Flower color (purple or white)
- Plant size (tall or dwarf)
- Position of flowers (axial or terminal)
How did Mendel cross pollinate pea plants?
Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments. Then he pollinated them by hand with pollen from other parent plants of his choice.
Why did Mendel count so many peas?
Keeping the peas.
By simply counting peas and keeping meticulous notes, Mendel established the principles of inheritance, coined the terms dominant and recessive, and was the first to use statistical methods to analyze and predict hereditary information.
Which trait is dominant in pea plants?
Green pod color is dominant and yellow is recessive. The shape of the pod has two traits – inflated and constricted. Inflated pod traits are dominant.
