In sexual reproduction typically half of the genes come from each parent. Sexually produced offspring are not identical to either parent. **(2.1e)** || M || Lecture || Book C || Unit Test ||  || In all organisms, genetic traits are passed on from generation to generation. **(2.2a)** || M || Lecture || Book C || Unit test ||  || Some genes are dominant and some recessive. Some traits are inherited by mechanisms other than dominance and recessive ness.(**2.2b)** || M || Lecture, Demo, Lab Activities || Book C Chapter 4 || Lab grade, Unit Test ||  || The Probability of traits being expressed can be determined using models of genetic inheritance. Some models of prediction are pedigree charts and Punnett squares. **(2.2c)** || M || Lecture, Punnett Squares, Probability Lab || Book C Chapter 4 || Lab grade, Unit Test,Final exam ||  || The processes of sexual reproduction and mutation have given rise to a variety of traits within a species. (**3.1a)** || M || Lecture || Book C Chapter 4 || Unit Test ||  || There are many methods of asexual reproduction, including division of a cell into two cells, or separation of part of an animal or plant from the parent, resulting in the growth of another individual. **(4.1b)** || M || Lecture || Book C Chapter 3 || Test ||  || The male sex cell is the sperm. The female sex cell is the egg. The fertilization of an egg by a sperm results in a fertilized egg. **(4.2a)** || M || Lecture || Book C Chapter 2,3 || Test ||  || In sexual reproduction, sperm and egg each carry one-half of the genetic information for the new individual. Therefore, the fertilization egg contains genetic information from each parent. **(4.2b)** || M || Lecture || Book C, Chapter 3 || Test ||  || In multicellular organisms, cell division is responsible for growth, maintenance, and repair. In some one-celled organisms, cell division is a method of asexual reproduction**. (4.4a)** || M || Cell City || Book C, Chapter 1 || Test ||  || In one type of cell division, chromosomes are duplicated and then separated into two identical and complete sets to be passed to each of the two resulting cells. In this type of cell division, the hereditary information is identical in all the cells that result. **(4.4b)**

Another type of cell division accounts for the production of egg and sperm cells in sexually reproducing organisms. The eggs and sperm resulting from this type of cell division contain one-half of the hereditary information. **(4.4c)** || M || Lecture || Book C, Chapter 1,3 || Unit Test ||  || R || Lecture Current Events || Book C || Unit Test ||  || I=introduce R=review M=mastery Grade Level: 7 Topic: Chemistry 4 The Physical Setting || 3 || See major understandings || Solubility, solute, solvent, surface area, solid, liquid, gas, states of matter, volume, insoluble, mixture, filtration, evaporation, physical change, chemical change, metals, nonmetals, noble gases, halogens, conservation, conservation of mass, reactant, product, atom, molecule, chemical bond, chemical reaction, reactant, product, proton, neutron, electron, endothermic, exothermic reactions, solute, solvent, solubility, || Solubility can be affected by the nature of the solute and solvent, temperature, and pressure.

Biological classification systems are arranged from general (kingdom) to specific (species). **(1.1h)** || M || Lecture, lab activities, taxonomic key || Book A, Book B || Lab grade, unit test, exam ||  || Each system is composed of organs and tissues, which perform specific functions and interact with each other, e.g. digestion, gas exchange, excretion, circulation, locomotion, control coordination, reproduction, and protection from disease **(1.2a)**

Tissue, organs and organ systems help to provide all cells with nutrients, oxygen and waste removal. **(1.2b)** || M || Lecture || Book A Book B || Unit test, final exam ||  || Disease breaks down the structures or functions of an organism. Some diseases are the result of failures of the system. Other diseases are the result of damage by infection from other organisms (germ theory). Specialized cells protect the body from infectious disease. The chemicals they produce identify and destroy microbes that enter the body. **(1.2j)** || M || Lecture || Book A, Chapter 2 || Unit test, final exam ||  || In asexual reproduction, all the genes come from a single parent. Sexually produced offspring are genetically identical to the parent. **(2.1d)** In sexual reproduction typically half of the genes come from each parent. Sexually produced offspring are not identical to either parent. **(2.1e)** || M || Lecture || Book C || Unit test ||  || Some organisms reproduce asexually. Other organisms reproduce sexually. Some organisms can reproduce both sexually and asexually. **(4.1a)** || M || Lecture || Book B, Chapter 1 Book A, Chapter 2 || Test ||  || There are many methods of asexual reproduction, including division of a cell into two cells, or separation of part of an animal or plant from the parent, resulting in the growth of another individual. **(4.1b)**

Methods of sexual reproduction depend upon the species. All methods involve the merging of sex cells to begin the development of a new individual. In many species, including plants and humans, eggs and sperm are produced. **(4.1c)** || M || Lecture || Book A, Chapter 2 || Test ||  || Fertilization and/or development in organisms may be internal or external. **(4.1d)** || M || Lab-Internal v. external fertilization || Book B || Lab Test ||  || Multicellular organisms exhibit complex changes in development, which begin after fertilization.
