Which of the following best explains the difference between micro and macro evolution? A. Microevolution is based on ideas, while macroevolution is based on facts B. Both micro and macro evolution are when you witness changes to a gene pool. C. Microevolution is small scale change to the gene pool of a population while macroevolution is larger scale changes that lead to speciation. D. Macroevolution is small scale change to the gene pool of a population while microevolution is larger scale changes that lead to speciation.

C. Microevolution is small scale change to the gene pool of a population while macroevolution is larger scale changes that lead to speciation.

Explanation:

Microevolution can be defined as a small change in the gene frequency within a gene pool of the species, these changes will be inherited by the organisms and there will not be any drastic change at the species level. But in case of macroevolution the large scale change occurs at the genetic level, which retain for long. This leads to development of new organisms or results in speciation.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.

the answer is sex-linked recessive.
