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.

Crossing over is a process in which exchange of segments occur between two non sister chromatids.

Explanation:

Crossing over is a process in which two non-sister chromatids of homologous chromosomes exchange the segments of genetic material with each other during meiosis. Due to this process, variation occurs in an organism.

Independent assortment is a process in which different alleles are sorted to different gametes which occurs independently and does not effect one another. This process occurs in metaphase of meiosis l.

Joining of sex cells is a process in which sex cells of male and female join together formed a zygote which turn into a new organism. These sex cells are formed during meiosis which are haploid in nature.

Mutation and crossing over are the factors that cause inherited genetic variations within populations.

Sudden change occurs in the genes of an organism due to the exposure of the cell to radiation or chemicals.
