Consider the following statements regarding the theory of linkage and choose the correct answer:
1. Genes are arranged in a linear fashion in the chromosomes
2. Genes that show linkage are situated in the chromosome
3. Linked genes remain in their original combination during the course of inheritance
4. The genes which are widely separated show strong linkage, while those closely located, have more chances to get separated by crossing over
Consider the following statements and choose the correct answer:
1. In the phenomenon of linkage and crossing over, the genes are arranged in a linear order in a chromosome
2. The linkage groups in an organism are equivalent to the number of chromosome pairs
3. The chances of crossing over are more between two closely placed genes as compared to the genes placed in far proximity
4. The position of genes is very definite in the chromatid
