To study genetics, Mendel chose to work with pea plants for three reasons: 1) they have easily identifiable traits, 2) they grow quickly, and 3) they can self-pollinate or be cross- pollinated.
Which characteristic of pea plants were important in their selection?
Mendel selected garden pea plant (Pisum sativum) as his experimental material because it has the following advantages: The plants were able to self fertilize. However, cross-pollination could be done easily in a controlled manner. They had easily observable traits such as plant height, flower color etc.
What characteristics of pea plants were important in the success of Mendel’s experiments?
To study genetics, Mendel chose to work with pea plants because they have easily identifiable traits (Figure below). For example, pea plants are either tall or short, which is an easy trait to observe. Furthermore, pea plants grow quickly, so he could complete many experiments in a short period of time.
What is the importance of pea plant genetically?
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 greatly expanded the understanding of genetic inheritance, and led to the development of new experimental methods.
What are the 7 characteristics of peas?
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)
Why did Mendel choose pea plant for his experiment Class 10?
Mendel selected pea plants for his experiments due to their easily detectable, contrasting characters.
What characteristics did Mendel study in pea plants?
Mendel studied the inheritance of seven different features in peas, including height, flower color, seed color, and seed shape. To do so, he first established pea lines with two different forms of a feature, such as tall vs. short height.
Why was the pea plant an ideal plant for Mendel?
Why did Mendel choose common, garden-variety pea plants for his experiments? Pea plants are a good choice because they are fast growing and easy to raise. They also have several visible characteristics that may vary.
What was Mendel’s most significant conclusion from his research with pea plants?
Traits are inherited in discrete units
So, the correct option is ‘Traits are inherited in discrete units one from each parent‘.
Why was it important for Mendel to study such a large sample of P?
They are able to sell fertilization. This makes us experiment easy to study and also he could make the experiment quickly. So the right answer for this question is selecting a large sample of pet plant to determine the probability of inheritance will be having or will be getting more accurate results.
What happens when pea plants showing two different characteristics?
When pea plants with round and green seeds are crossed with wrinkled and yellow seed (both pure line), FI generation plants have round and yellow seed.
Which is one of the seven characteristics that Mendel observed in pea plants?
The characteristics included plant height, seed texture, seed color, flower color, pea-pod size, pea-pod color, and flower position.
What are the 7 characteristics of a plant?
The seven characteristics of plants are nutrition, respiration, movement, excretion, growth, reproduction, and Sensitivity.
Which characteristics of pea plant was not used by Mendel?
Mendel chose Pisum sativum (pea plant) for his experiments. He selected seven traits of pea plant. It excludes plant colour. He chose characters like flower colour, flower position, stem length, seed shape, seed colour, pod shape and pod colour.
What is pea plant called?
pea, (Pisum sativum), also called garden pea, herbaceous annual plant in the family Fabaceae, grown virtually worldwide for its edible seeds.
How did Mendel control pollination in 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.
Which of the following is a dominant character in pea?
So, the correct answer is ‘green pod‘.
Why was Mendel successful in his experiment?
The main reason for the success of Mendel was that he took one character at one time in his experiments of hybridization. So it was easy. Other scientists also performed cross-hybridization for many characters, this made the experiments complex and they could not accurately explain the results.
What are the four important principles or laws developed by Mendel?
The Mendel’s four postulates and laws of inheritance are: (1) Principles of Paired Factors (2) Principle of Dominance(3) Law of Segregation or Law of Purity of Gametes (Mendel’s First Law of Inheritance) and (4) Law of Independent Assortment (Mendel’s Second Law of Inheritance).
What are the important conclusions made by Mendel Make a list of these conclusions?
—and, after analyzing his results, reached two of his most important conclusions: the Law of Segregation, which established that there are dominant and recessive traits passed on randomly from parents to offspring (and provided an alternative to blending inheritance, the dominant theory of the time), and the Law of
What is the conclusion of Mendel experiment?
In 1865, Mendel presented the results of his experiments with nearly 30,000 pea plants to the local Natural History Society. He demonstrated that traits are transmitted faithfully from parents to offspring independently of other traits and in dominant and recessive patterns.
