• A. The random mutation causes changes in the DNA sequence of a gene
• B. Chromosomes are the basis for all genetic inheritance.
• C. Explains the mechanism underlying the laws of Mendelian inheritance.

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A

The random mutation causes changes in the DNA sequence of a gene

B

Chromosomes are the basis for all genetic inheritance.

C

Explains the mechanism underlying the laws of Mendelian inheritance.

D

Chromosomes are linear structures with genes located at loci

chromosomal theory of inheritance was developed by Sutton and Bovery. It explains the

• Random mutation creates changes in the DNA sequence of a gene
• Chromosomes seen in all dividing cells, pass from one generation to the next basis for all genetic inheritance.
• Chromosomes are linear structures with genes located at specific sites called loci along them.
• Mechanism underlying the laws of Mendelian inheritance by identifying chromosomes
