Question

How many true-breeding pea plant varieties did Mendel select as pairs, which were similar except in one character with contrasting traits ?

• A. $4$
• B. $8$
• C. $14$
• D. $2$

Answer 1

The correct option is C $14$

A true breeding line refers to the plant that has been self-pollinated continuously and produced generations that were stable in the inheritance of the character.

Mendel selected $14$ true-breeding pea plant varieties, as pairs which were similar except for one character with contrasting traits.
Hence, the correct answer is $14$.
