What is special about pea plant in genetics?
What is special about pea plant in genetics?
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. Mendel called the visible form the dominant trait and the hidden form the recessive trait.
What are the 7 characteristics of pea plants?
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)
What is pea plant in biology?
1. (Science: botany) A plant, and its fruit, of the genus Pisum, of many varieties, much cultivated for food. It has a papilionaceous flower, and the pericarp is a legume, popularly called a pod. The name pea is given to many leguminous plants more or less closely related to the common pea.
What is the importance of pea plant?
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.
What was Mendel’s experiment with pea plants?
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.
What happens when pea plants showing two different characteristics?
According to this law when two characters are taken into consideration for a cross (dihybrid cross), each one of these characters is independent to pass in the subsequent generation. It means that inheritance of a pair of factors or genes is independent of the other pairs of factors or genes.
How many traits Mendel found on pea plants?
seven different characteristics
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.
Where do peas grow?
Where to Grow Peas. Peas are a cool-season vegetable, and do best in a climate where there are two months of cool growing weather, either spring planting in the northern regions or fall planting in the warmer, southern regions. They are hardy to frost and light freezes.
Where does pea grow?
The major producing countries of field peas are Russia and China, followed by Canada, Europe, Australia and the United States. Europe, Australia, Canada and the United States raise over 4.5 million acres and are major exporters of peas.
Are pea plants edible?
Almost every part of the pea plant is edible Of course we know the peas themselves are delicious, but in many varieties such as snow peas and sugar snap peas, the pods are also edible. An often overlooked but delicious part of the pea plant is the pea shoot.
What are facts about pea plants?
Facts About Pea Plants. Peas have been eaten since ancient times, and they are grown today as an essential member of the vegetable garden. The role peas play in restoring soil fertility and their preference for cool weather distinguishes them from many other vegetable plants.
What are the seven characteristics of pea plants?
Plant Hybridization Experiments. Mendel used seven pea plant traits in his experiments which include flower color (purple or white), flower position (axil or terminal), stem length (long or short), seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted), and pod color (yellow or green).
Which type of soil is best for pea plants?
Pea plants grow best in neutral soil with a 6.0 to 6.5 pH. Test the planting area with a commercially available soil test kit to obtain the pH value. Pea plants adapt to slightly alkaline or slightly acidic soil.
What are the conditions to grow pea plants?
As peas can prefer cool growing conditions and will tolerate light frosts, they may be planted as soon as the ground can be worked and will germinate in a wide range of soil temperatures, 4-24°C (40-75°F). Sow pea seed 1 to 1½” deep, 1-2 inches apart in double rows spaced 3-6” apart, 24” between the next double row.
