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.

Chapter 11.1 & 11.2 notes section 11.1 1. every living thing has a set of ? inherited from its parents. 2. after becoming a ? , mendel spent several years studying ? and mathematics at the university of vienna. 3. during sexual reproduction, male and female reproductive cells join, a process known as ? . 4. pea flowers are normally ? , which means that sperm cells in pollen fertilize the egg cells in the ? flowers. 5. when mendel crossed plants with ? characters for the same trait, the resulting offspring had only one of the characters. 6. a ? is a specific characteristic, such as seed color or plant height, that varies from one individual to another. 7. filius and filia are the latin words for ? and ? . 8. the offspring of crosses between parents with different traits are called ? . 9.to mendel's surprise, all of the offspring had the character of only ? of the parents. 10. mendel's first conclusion was that biological inheritance is determined by ? that are ? from one generation to the next. 11. scientist calls the chemical factors that determine traits ? . 12. mendel's second conclusion is the ? . 13. the principle of dominance states that some alleles are ? and others are ? . 14. when mendel allowed the f1 plants to reproduce by self-pollination the traits controlled by ? alleles reappeared in about ? of the f2 plants in each cross.
