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

Tracking the evolutionary history of individual genes in a group of species can reveal which genes have remained in a genome for a long time and which genes have been horizontally transferred between species.
When comparing pairs of genes or sets of genes in different genomes for this purpose, it is not mandatory for the genes to be orthologs.
Other functional classification schemes for genes include a broader category for genes involved in the same biological process, e.g., a three-group scheme for energy-related, information-related, and communication-related genes has also been used.
