The answer is the second one: To act as a 'blueprint' for an organism's genetic information.

Explanation for each option:

  • To show the physical structure of chromosomes: This option is incorrect. While genome maps can provide information about the location of genes on chromosomes, their main purpose is not to show the physical structure of chromosomes. That is more the role of a karyotype or a cytogenetic map.

  • To act as a 'blueprint' for an organism's genetic information: This option is correct. A genome map provides a comprehensive overview of the genetic makeup of an organism, detailing the location and function of genes and other significant sequences. It serves as a 'blueprint' for understanding the genetic instructions that govern the development and functioning of an organism.

  • To illustrate the evolution of species: This option is incorrect. While genome maps can be used to study evolutionary relationships by comparing the genomes of different species, illustrating evolution is not their primary purpose.

  • To demonstrate how diseases are inherited: This option is incorrect. Although genome maps can help identify genes associated with certain diseases and understand inheritance patterns, their main purpose is not specifically to demonstrate disease inheritance.

In summary, the main purpose of a genome map is to act as a 'blueprint' for an organism's genetic information.
