Question

Which character was dominant among the 7 characters in Mendel’s experiment?
A. Plant height – Dwarf
B. Flower position – Terminal
C. Pod colour – Green
D. Seed colour – Green

Answer 1

As we all know that Mendel choose garden pea, Pisum sativum for his experiment and studied their characters which included the stem length, lower colour, flower position, pod shape, pod position, cotyledon colour and seed form.

Complete answer:
We all know that Mendel chose garden pea, Pisum sativum for his experiment since it has several advantages like well-defined discrete characters, bisexual flowers, predominant self-fertilization, easy hybridization, easy to cultivate and short life span.
He studied the characters of the pea plant which are called Mendelian characters and there are seven pairs of these contrasting characters that he included which are the stem length, lower colour, flower position, pod shape, pod position, cotyledon colour and seed form.
These characters were represented on the basis of their dominance and recessivity. We can represent them in a tabular form as:

Characters	Dominant	Recessive
Stem length	Tall	Dwarf
Flower position	Axial	Terminate
Flower colour/seed coat colour	Violet/grey	White/white
Seed form	Round	Wrinkled
Pod shape	Inflated	Constricted
Pod colour	Green	Yellow
Cotyledon colour	Yellow	Green

Comparing among the given options we can see that Green pod colour is the dominant character and all other are recessive characters.

Therefore we can say that the correct answer is option (C).

Note: In his same experiment, Mendel located these seven pairs of contrasting characters on four different chromosomes. On chromosome 1 he found the flower colour and seed colour, on chromosome 4 He located three characters which are flower position, pod shape and pod height. Pod colour was found on the chromosome and seed shape was found on chromosome 7.
