(b) Wrinkled seed: Round is dominant: wrinkled is recessive.
What are the characters of pea plant?
The characteristics of a pea plant are:

- 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)
How many contrasting characters are there?
The correct answer is 7. Mendel selected 7 contrasting characters for his experiment.
What are the seven traits 7 of garden pea that he studied?
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).
What are the 3 laws of Mendel?
The three laws of inheritance proposed by Mendel include: Law of Dominance. Law of Segregation. Law of Independent Assortment.
What is contrasting character class 10?
The pair of contrasting characters means that a single character exhibits two opposite characters.
What is the contrasting trait of a yellow seed in a pea plant?
Yellow is the dominant one whereas Green is the recessive allele.
What is contrasting characteristic?
Contrasting character difference means two organisms differing in one particular character. For example, tall and dwarf are two contrasting characters for height of plant.
What are the 7 characteristics of plants?
The seven characteristics of plants are nutrition, respiration, movement, excretion, growth, reproduction, and Sensitivity.
Which characters 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.
Which characteristics of pea plant was not used by Mendel?
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 a contrasting character called?
A pair of contrasting characters is called alleles.
How many pairs of contrasting characters are in pea plants?
Mendel studied seven pairs of contrasting traits in pea plants and proposed the Laws of Inheritance. Statement II: Seven characters examined by Mendel in his experiment on pea plants were seed shape and colour, flower colour, pod shape and colour, flower position and stem height.
How many characters are in pea pods?
So, the correct answer is 7.

What is pea plant called?
pea, (Pisum sativum), also called garden pea, herbaceous annual plant in the family Fabaceae, grown virtually worldwide for its edible seeds.
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.
What are Mendel’s 4 principles?
The Mendel’s four postulates and laws of inheritance are: (1) Principles of Paired Factors (2) Principle of Dominance(3) Law of Segregation or Law of Purity of Gametes (Mendel’s First Law of Inheritance) and (4) Law of Independent Assortment (Mendel’s Second Law of Inheritance).
What is Mendel’s 1st and 2nd law?
Mendel’s first law describes the segregation of the two copies of alleles of a particular gene into the gametes. Mendel’s second law describes the independent assortment of alleles of different genes from each other during the formation of gametes.
