Answer:
The correct answer to the question: From these data. one can conclude that there are 20 map units between the G and E loci, would be: True.
Explanation:
Inheritance of traits from chromosomes, especially during the crossover of genetical information in meiosis, is a pretty complex topic. However, with the advancement of genetics, researchers have been able to understand the way in which living beings are able to inherit specific traits, and also why, these traits are distributed in the way they are to the progeny. The answer was given then through the proposal of the Centimorgan, also known as map unit. Map units then became in genetics a means by which scientists were able to measure genetic linkage, or better said, measure the tendency of certain chromosomes to link with another when distance between them was reduced, especially during the process of meiosis. Ultimately, map units helped researchers visualize the conditions under which specific genetic material in chromosomes tended to be paired and passed on to daughter cells with others that were close by, and to what extent. In this case, 20 map units show the amount of times the G and E loci, given their positions, interacted and linked with other chromosomes nearby.
