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.
Which trait of garden pea is recessive?
Explanation: Mendel based his experiments on pea plants and studied seven pairs of contrasting traits. Yellow seed colour is the dominant trait and green seed colour is the recessive trait.
What 7 traits did Mendel study in pea plants?
The characteristics included plant height, seed texture, seed color, flower color, pea-pod size, pea-pod color, and flower position.
How many contrasting traits in pea are recessive?
So, the correct option is ‘2‘.
How many traits did Mendel experiment with in 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.
What are dominant and recessive traits in pea plants?
The following table shows each of the traits and which traits are dominant and which recessive.
Explore.
| Trait | Dominant Expression | Recessive Expression |
|---|---|---|
| Form of ripe seed (R) | Smooth | Wrinkled |
| Color of seed albumen (Y) | Yellow | Green |
| Color of flower (P) | Purple | White |
| Form of ripe pods (I) | Inflated | Constricted |
What do you mean by recessive trait?
Refers to a trait that is expressed only when genotype is homozygous; a trait that tends to be masked by other inherited traits, yet persists in a population among heterozygous genotypes.
Why did Mendel choose pea plant for his experiment Class 10?
Complete Answer:
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 are the 3 laws of Mendel?
The law of inheritance was proposed by Gregor Mendel after conducting experiments on pea plants for seven years. Mendel’s laws of inheritance include law of dominance, law of segregation and law of independent assortment.
Which generation in Mendel’s experiments showed a 3 1 ratio of traits?
F2 generation
The F2 generation always produced a 3:1 ratio where the dominant trait is present three times as often as the recessive trait. Mendel coined two terms to describe the relationship of the two phenotypes based on the F1 and F2 phenotypes.
What are the 7 pairs of contrasting characters studied by Mendel?
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 were chosen by Mendel?
Mendel proposed laws of inheritance based on artificial pollination or cross-pollination experiments using 14 true-breeding pea plant varieties having seven pairs of contrasting traits. The traits include colour, shape, the colour of pods, the shape of pods, size of the plant, position of flowers and colour of flowers.
How do Mendel’s experiments show that traits Maybe dominant or recessive Class 10?
Mendel’s experiments show that the Traits may be dominant or recessive by performing a monohybrid cross. Monohybrid cross between two pure breeding varieties always obtained hybrid progeny exhibiting one parental trait while the opposite trait was never expressed in the F1 generation.
What was Mendel’s experiment with 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.
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.
Is a recessive character of pea plant?
The wrinkled seed character is recessive in garden pea plants. Gregor John Mendel, known as ‘father of genetics’, chose garden pea (Pisum sativum) for his experiments.
The _______ character is recessive in garden pea plants.
| Character | Dominant | Recessive |
|---|---|---|
| Color of unripened pods | Green | Yellow |
Which of the following is not a recessive trait of pea plant?
The axial flower position was recessive to terminal position. Green seed and wrinkled seeds were recessive to yellow and round seeds; yellow, constricted pods were recessive to green and full pods. Dwarf stem and white flowers were recessive to tall stem and violet flowers. Thus, the correct answer is option C.
What are 2 examples of recessive traits?
Examples of Recessive Traits
- Attached earlobes.
- Inability to roll tongue.
- Five fingers.
- Type O Blood.
- Hitch-hiker’s thumb.
- Blue eyes.
- Albinism: an albino lacks pigment or coloration in the skin.
- Sickle cell anemia: abnormal red blood cells make it difficult to transport oxygen throughout the body.
Is having 5 fingers a recessive trait?
In fact most animals around today only have five digits (fingers or toes) on their limbs. But sometimes something goes wrong and an animal ends up with extra or missing digits. And surprisingly, having five fingers in these cases is usually a recessive trait.
Which genes are recessive?
X-linked recessive – where the gene for a trait or condition is recessive, and is on the X-chromosome. Y-linked – where the gene for a trait or condition is on the Y-chromosome.
