<h3><u>Answer;</u></h3>
D) Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.
<h3><u>Explanation;</u></h3>
- <em><u>Mutations are sudden, random changes that occur spontaneously in the genetic make up of an organism.</u></em> Mutation are caused by various factors which includes errors in meiosis, and other factors such as chemical mutagens.
- <em><u>Mutations may be beneficial and may play an important role in evolution as they are raw material of genetic variation</u></em>. <em><u>Mutations may lead to genetic variations in the genetic make up of an organism . Therefore mutations are important to mutation since they create new DNA sequences for a given gene and thus resulting to new alleles.</u></em>
Answer: The DNA repair process was called recombination repair.
Explanation: A sister or homologous chromatide is used to generate recombination and be repaired in this sort of cases.
Answer:
A. two or more genes because most genetic characteristics or traits are controlled by many genes.
The answer is B because theorys explain what happens and why it happens.
