Question

The genes controlling the seven pea characters studied by Mendel are now known to be located on how many different chromosomes?

• A. 5
• B. 6
• C. 4
• D. 7

Answer 1

The correct option is C

4

The correct option is C.

Explanation of correct option:

1. Mendel studied 7 characters of the pea plant in his experiments.
2. The characters chosen by Mendel were seed color, seed shape, stem height, flower color, flower position, pod color, and pod shape.
3. All the genes controlling these seven pea characters are located on 4 different chromosomes (1,4,5,7).
4. The genes for seed color and flower color are located on chromosome 1.
5. Genes for stem height, flower position and pod shape are located on chromosome 4
6. Genes for pod color genes are located on chromosome 5
7. Genes for seed shape is located on chromosome 7.

Final answer: The genes controlling the seven pea characters studied by Mendel are now known to be located on 4 different chromosomes.
