Question
Read the given statements carefully. Statement I: All genes are essentially present on the chromosome Statement II: Genes, that are located on the same chromosome will always pass together from one generation to another Statement III: The distance between two genes can never be mapped without cloning experiments Statement IV: All genes are essentially overlapping present on the chromosome Pick the INCORRECT interpretation for the molecular explanation of chromosomal theory of inheritance. Statement I Statement II Statement III Statement IV
Solution
The incorrect interpretation for the molecular explanation of chromosomal theory of inheritance is Statement II. While it is true that genes located on the same chromosome are often inherited together, this is not always the case due to the process of crossing over during meiosis. Crossing over can result in the recombination of genes, meaning that genes on the same chromosome can be separated and passed on to offspring independently.
Statement III is also incorrect. The distance between two genes can be mapped without cloning experiments. This is done through the process of genetic mapping, which involves determining the relative positions of genes on a chromosome and the distance between them based on recombination frequencies.
Statement I and IV are correct. All genes are present on chromosomes, and they can be overlapping.
