Answer:
B. The chromosomes exchange genetic information.
Explanation:
Crossing over of tetrads during meiosis is very important for the exchange of genetic information.
This step of meiosis allows for each chromosome to be genetically unique and distinct from the others, creating genetic variation.
Crossing over does not double the number of chromosomes or reduce the number. The number of chromosomes stays the same.
So, the correct answer is B. The chromosomes exchange genetic information.
In many larger organisms, evolution has favored lungs and a digestive tract with more branching or folds. Evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The heritable characteristics of biological populations change over successive generations with a diversity at every level of biological organization, including the levels of species, individuals organisms, and molecules.
