Question

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

• A. 6
• B. 5
• C. 7
• D. 4

Answer 1

The correct option is D 4

Genes are the distinct sequence of nucleotides present in DNA that code for a specific protein. DNA stands for deoxyribonucleic acid. DNA is located on chromosomes.
The genes controlling the seven pea characters studied by Mendel are now known to be located on 4 different chromosomes. The table given below describes them.

We see the involvement of chromosomes 1,4,5, and 7. Pea plants have 14 chromosomes. Out of those, 4 chromosomes contain the genes controlling the seven pea characters studied by Mendel.
