The phenomenon of populations of organisms changing from generation to generation is known as biological.
Blababa [14]

The phenomenon of populations of organisms changing from generation to generation is known as biological evolution. 

<h3>What is biological evolution?</h3>

Biological evolution is a scientific term that deals with the change in inherited traits through successive generations in an organism's population. For example, penguins have typical wings over swim-friendly flippers which were there for many generations. It is also called microevolution. Biological evolution is important because it helps us to understand why an organism is the way they are. Mutation, genetic drift, gene flow, and non-random mating are some of the causes of biological evolution. Heredity and Reproduction are the top conditions for biological evolution.

Which can be accomplished by an interrupted mating experiment between Hfr and F- bacteria? Interrupted mating experiments can de
eimsori [14]

Answer:

Interrupted mating experiments can determine gene order on the Hfr bacterial chromosome.

Explanation:

Interrupted mating is a technique used in experiments involving microbiology. This experiment was created by geneticists François Jacob and Elie Wollman, in the late 1950s. This technique allows the mapping of the genes of the bacteria involved in the place where the conjugation was interrupted, within monitored and controlled time intervals. In this way, the technique allows showing the transfer mechanisms and the gene transfer itself.

In relation to the question above, we can say that the interrupted mating experiments can determine the order of the genes on the bacterial chromosome Hfr.
