Pedigree Analysis
* A pedigree is a family tree that describes the interrelationships of parents and children across generations
* Inheritance patterns of particular traits can be traced and described using pedigrees
* Pedigrees can also be used to make predictions about future offspring
* We can use the multiplication and addition rules to predict the probability of specific phenotypes
Recessively Inherited Disorders
* Many genetic disorders are inherited in a recessive manner
* These range from relatively mild to life-threatening
Probability laws govern Mendelian inheritance
* Mendel?s laws of segregation and independent assortment reflect the rules of probability
* When tossing a coin, the outcome of one toss has no impact on the outcome of the next toss
* In the same way, the alleles of one gene segregate into gametes independently of another gene?s alleles
Genetic variation produced in sexual life cycles contributes to evolution
* Mutations (changes in an organism?s DNA) are the original source of genetic diversity
* Mutations create different versions of genes called alleles
* Reshuffling of alleles during sexual reproduction produces genetic variation
Concept 13.3: Meiosis reduces the number of chromosome sets from diploid to haploid
* Like mitosis, meiosis is preceded by the replication of chromosomes
* Meiosis takes place in two consecutive cell divisions, called meiosis I and meiosis II
* The two cell divisions result in four daughter cells, rather than the two daughter cells in mitosis
* Each daughter cell has only half as many chromosomes as the parent cell
Meiosis and Sexual Life Cycles
Variations on a Theme
* Offspring resemble their parents more than they do unrelated individuals
* Heredity is the transmission of traits from one generation to the next
* Variation is demonstrated by the differences in appearance that offspring show from parents and siblings
* Genetics is the scientific study of heredity and variation

CHAPTER 9: STOICHIOMETRY
The following pages contain the bulk (but not all) of the information for the chapter 9 test.
Focus on this content, but make sure to review class notes, activities, handouts, questions, etc.
If you study this document and NOTHING else, you should at least be able to PASS the test.
