These plants are easy to control pollination artificially. Self pollination can be prevented by removing anthers from the flowers. The pollen from a flower of another plant of the same species can be transferred to the stigma of the flower. Thus cross – pollination is also possible in this plant.
What are the advantages of pea plant?
Answer: Mendel selected garden pea as his experimental material because it had the following advantages: (i) The pea plants showed a number of well defined contrasting characters. (ii) It has perfect bisexual flowers containing both male and female parts. The flowers are predominantly self pollinating.
What was the advantage of Mendel work on pea plant?
Mendel studied the common garden pea plant, Pisum sativum because it was easy to cultivate and had a relatively short life cycle of 3 months. The plant exhibited discontinuous characteristics such as flower color and pea texture.
What are some of the advantages of using a garden pea for genetic studies?
Gregor Mendel chose the pea plants for his experiments because the garden pea is an ideal subject in the study of genetics for the following reasons:
- presence of observable traits with contrasting forms.
- produces many offspring in one cross.
- short life cycle.
- ease in manipulating pollination (cross-pollination)
What are the advantages of using pea plants to study heredity select the three correct choices?
Mendel choose pea plants for his experiments because of the following reasons: (i) The flowers of this plant are bisexual. (ii) They are self-pollinating, and thus, self and cross-pollination can easily be performed. (iii) The different physical characteristics were easy to recognize and study.
What part of the plant are peas?
The pea is most commonly the small spherical seed or the seed-pod of the pod fruit Pisum sativum. Each pod contains several peas, which can be green or yellow. Botanically, pea pods are fruit, since they contain seeds and develop from the ovary of a (pea) flower.
How did Mendel control the mating of his pea plants?
Mendel controlled breeding by separating the male and female parts of the flowers so they couldn’t reproduce on their own. Next, he used a small brush to move pollen between plants. Lastly, pea plants had a number of visible traits, called phenotypes, that were easy to identify.
What is law of dominance Class 10?
Mendel’s law of dominance states that: “When parents with pure, contrasting traits are crossed together, only one form of trait appears in the next generation. The hybrid offsprings will exhibit only the dominant trait in the phenotype.” Law of dominance is known as the first law of inheritance.
Why did he choose pea plants?
(a) Reason for the selection of pea plants for the genetic experiments. Easy to grow in the garden. The flowers of pea plants are hermaphrodite, i.e flowers have bisexual characteristics. The generation time of pea plants is less.
Which characteristic of pea plants were important?
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 are peas used for?
Peas are a good source of vitamins C and E, zinc, and other antioxidants that strengthen your immune system. Other nutrients, such as vitamins A and B and coumestrol, help reduce inflammation and lower your risk of chronic conditions, including diabetes, heart disease, and arthritis.
Why is a pea called a pea?
In AngloSaxon the word became pise or pisu; later, in English it was “pease.” So many people thought pease was plural that they persisted in dropping the “s” sound, thus making the word “pea.” The Latin name resembles the older Greek pisos, or pison.
WHAT DOES pea stand for?
Pulseless electrical activity
Pulseless electrical activity (PEA) refers to cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not. Pulseless electrical activity is found initially in about 55% of people in cardiac arrest. Pulseless electrical activity. Other names.
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)
What is the definition of law of segregation in biology?
The Principle of Segregation describes how pairs of gene variants are separated into reproductive cells. The segregation of gene variants, called alleles, and their corresponding traits was first observed by Gregor Mendel in 1865. Mendel was studying genetics by performing mating crosses in pea plants.
What is the difference between law of segregation and law of Independent Assortment?
Law of segregation: During gamete formation, the alleles for each gene segregate from each other so that each gamete carries only one allele for each gene. Law of independent assortment: Genes for different traits can segregate independently during the formation of gametes.
What do you understand about independent inheritance of traits?
Independent inheritance of traits is explained in the form of Law of Independent Assortment by Mendel. Law of Independent Assortment states that, as two traits are combined in a hybrid, each trait gets segregated, so that they become independent of the other trait.
What happens when pea plants showing two different characteristics?
Answer. Answer: If the inheritance of more than one pair of characters is studied simultaneously the factors of genes for each pair of characters sort out independently.
Why did Mendel study pea plants quizlet?
Why did Mendel study pea plants? Mendel studied pea plants because they reproduced sexually and had traits that were easily observable.
Are peas good for your skin?
Good for skinPeas are an excellent source of Vitamin C, which plays a significant role in in the production of collagen. Collagen helps keep the skin firm and glowing. Vitamin C also protects the cells from damage caused by free radicals. The antioxidants help fight oxidative damage caused by the free radicals.
