Question

Step 3: Make a claim.

a) Recall what you know about crossing over, independent assortment, and random joining of
sex cells during sexual reproduction.
b) Now, go back to the claims in Step 2a. Do you support these claims? If so, do you support the
totality of the claims or just parts of the claims?
c) Based on your prior knowledge, make a claim about the factors that cause inherited genetic
variations within populations. Also make a claim about the effects of mutations. Write your
claim in your notebook.
Step 4: Conduct research to support your claim.
a) For each part of your claim, conduct research to provide two examples of scientific
information that supports it.
i. Scientific information may be gathered from reputable websites, scientific journals,
and video lessons from scientists or educators, information from government
agencies, or interactive activities from universities or other educational sites.
b) Be sure to take notes in your notebook.
c) Keep track of the sources you use. You will need to cite them later.

Answer 1

Answer: Inherited genetic variations are caused by the process of meiosis.

Inherited genetic variations are caused by the process of meiosis. Meiosis can be described as a phenomenon in which parent cell divides into four new daughter cells each having half the number of chromosomes of the parent cell. During meiosis, the phenomenon of crossing over and homologous recombination occurs which cause inherited genetic variations.

Mutations can also cause genetic variations to arise. A mutation can be described as a change in the genetic sequence which can occur naturally or can be induced. The change in the genetic sequence causes variations to arise.
