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 are the 7 contrasting characters of pea?
7 pairs of contrasting characters in pea plants were studied by Mendel in his experiments.
- 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 many traits do Peas have?
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.
What were the seven traits studied by Mendel?
Mendel studied 7 characters of the pea plant in his experiments. The characters chosen by Mendel were seed color, seed shape, stem height, flower color, flower position, pod color, and pod shape. All the genes controlling these seven pea characters are located on 4 different chromosomes (1,4,5,7).
What traits do pea plants come in pairs?
- A Rough and smooth.
- C Yellow and green.
- D Short and tall. Mendel found that pea plants have some traits which come in pairs like the seed is either rough or smooth. It is either yellow or green, and the height of the plant is either tall or short.
What are the seven contrasting traits?
There are seven contrasting traits in pea plants studied by Mendel :
- Plant height ( Tall and dwarf )
- Seed shape ( Round and wrinkled )
- Seed colour ( Yellow and green )
- Flower position ( Axial and terminal )
- Flower colour ( Violet and white )
- Pod shape ( Inflated and constricted )
- Pod colour ( Green and yellow )
What are the characteristics of pea plant?
The characteristics of a pea plant are:
- Colour of seed (green or yellow)
- Shape of seed (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 are the dominant traits in garden peas?
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.
Which is a dominant trait that Mendel observed in pea plants?
Mendel called the visible form the dominant trait and the hidden form the recessive trait. In the second generation, after plants were allowed to self-fertilize (pollinate themselves), the hidden form of the trait reappeared in a minority of the plants.
What are traits give an example?
A trait, as related to genetics, is a specific characteristic of an individual. Traits can be determined by genes, environmental factors or by a combination of both. Traits can be qualitative (such as eye color) or quantitative (such as height or blood pressure).
What was Mendel’s experiment with pea plants?
Mendel crossed pure lines of pea plants. Dominant traits, like purple flower colour, appeared in the first-generation hybrids (F1), whereas recessive traits, like white flower colour, were masked. However, recessive traits reappeared in second-generation (F2) pea plants in a ratio of 3:1 (dominant to recessive).
What traits in pea plants is being studied in the cross above?
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.
Which one of the following traits of garden pea is a recessive feature?
Solution : Green seed colour was a recessive characters.
How many contrasting traits does a pea pod have?
2 contrasting characters
Among the 7 distinct characters of pea plant, Mendel observed 2 contrasting characters of pod of a pea plant. They are pod colour (yellow or green) and pod shape (inflated or constricted).
What is inheritance and control traits?
The genes present in the DNA control characteristics or traits. The phenotypic or physical expression of a character depends upon the genotypic constitution. The expressed traits are a result of the specific genotypic combination of the alleles, which are a pair of genes .
What are the seven characters selected by Mendel?
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. All these characters belong to different chromosomes in the pea plant.
What is contrasting trait?
A trait is any character like height, shape, color etc. A trait is generally represented by two forms. When these two forms are opposite to each other they are termed as contrasting trait. For example contrasting traits for height is tall and dwarf.
How many traits were colour based contrasting traits?
There were seven contrasting traits taken by Mendel for his experiments on pea.
What are the 7 pairs of traits Mendel worked with in pea plants?
Mendel selected seven pairs of contrasting characters of pea plants for his experiments which are as follows:
- 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.
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 are the dominant and recessive traits of the pea plant’s seed shape?
The terminal flower position was recessive to axial position; yellow seed colour was recessive to green colour; green pod colour was dominant to yellow and round seed shape was dominant to wrinkled shape.
