The mating of the garden-pea flowers can be easily controlled because the male and female reproductive parts are enclosed within the same flower. 3. the garden-pea is small, grows easily, matures quickly, and produces many offsprings.
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 are the characteristic of garden peas?
What Are The 7 Characteristics Of Pea Plants?
- Colour (green or yellow)
- Shape (round or wrinkled)
- Colour of pod (green or yellow)
- Shape of pod (constricted or inflated)
- Size of the plant (tall or dwarf)
- Position of flowers (axial or terminal)
- Colour of flower (purple or white)
Can pea reproduction be controlled?
Pea plants are also easy to cross, or mate in a controlled way. This is done by transferring pollen from the anthers (male parts) of a pea plant of one variety to the carpel (female part) of a mature pea plant of a different variety.
What characteristics of the garden pea made this organism a good choice for Mendel’s experiments on heredity?
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. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate.
What happened when Mendel crossed two traits of a character in a pea plant?
Answer: Mendel also experimented to see what would happen if plants with 2 or more pure-bred traits were cross-bred. He found that each trait was inherited independently of the other and produced its own 3:1 ratio. This is the principle of independent assortment .
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)
Which characteristics of pea plant is dominant?
Green pod color is dominant and yellow is recessive. The shape of the pod has two traits – inflated and constricted.
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.
What are the essential characteristics of plants?
The essential characteristics of plants
- Plants are photosynthetic.
- Plants are multicellular, primarily terrestrial organisms descended from green algae.
- Plant growth is indeterminate and adapted to gather diffuse resources.
- Shoots consist of simple repeated units exhibiting serial homology.
Which has the most control of traits and inheritance?
Genes have the most control of traits and inheritance.
They are the basic unit of inheritance. Some traits are controlled by a single gene while other…
How do peas self-pollinate?
Pea flowers are perfect and self- pollinating. The flowers open early in the morning and do not shut. The anthers shed pollen the night before the flower opens, but this does not reach the stigma until the flower is tripped, usually by the wind.
Which of the following characteristics of pea plants was not used by Mendel in his experiments?
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 the advantage of large flowers of pea for artificial crossing purpose?
Owing to its anatomy, it was easy to control the self-pollination of the plant and cross-fertilization between desired parents could be accomplished artificially.
Why did Mendel select garden pea plants for his breeding experiments?
(a) (i) Mendel selected garden pea plant for his experiment on heredity because it is self pollinating and self fertilizing plant so pure lines are easily available.
Which among the following characters selected by Mendel in a pea plant is a recessive character?
Complete answer: Green cotyledon colour was one of the recessive traits studied by Mendel in garden pea.
What Did Mendel’s cross-pollination of pea plants prove?
Mendel’s cross-pollination of pea plants proved that genes of two separate organisms are passed to their offspring.
What trait in pea plants is being crossed?
What trait in pea plants is being studied in the cross shown above? The trait that is being studied is the height of the pea plants.
How many traits did each pea plant characteristics have?
During this time, Mendel observed seven different characteristics in the pea plants, and each of these characteristics had two forms (Figure 3). The characteristics included height (tall or short), pod shape (inflated or constricted), seed shape (smooth or winkled), pea color (green or yellow), and so on.
How many dominant characteristics are present in pea plant from given list?
Axial flower, yellow pod, flower position, pod shape, terminal flower, wrinkled seed, tall plant, white flower, seed shape.
How many traits in garden pea plants selected by Mendel for the genetics experiment were recessive?
There were 7 characters of the pea plant which were selected by Mendel for the experiments. The characters which were chosen by Mendel for his study were stem height, flower colour, flower position, pod shape, pod colour, seed shape, seed colour.
