Question

• A. Eccentrically
• B. Linear
• C. Circular
• D. None of the above

Answer 1

Answer: (B)

The correct option is A Linear
The chromosomal theory of inheritance was proposed by Mendel. This theory states that there are certain factors which are passed on from one generation to the next in pairs which are present on the homologous chromosomes. The genes are arranged in a linear manner on the chromosomes. The genes are present along the length of the chromosome. The two homologous chromosomes form a pair only during cell division. The image shows location of the genes on certain chromosomes in Drosophila.

Thus, the correct answer is option A.
