39. Break students down into groups of 3-4. Heredity and variation are two processes involved in the inheritance of characters from parents to the offspring during sexual reproduction.An offspring produced by sexual reproduction does not completely resemble the parents. In sexual reproduction, chromosomes can sometimes swap sections during the process of meiosis (cell division), thereby creating new genetic combinations and thus more genetic variation. "Title: Subtitle of Part of Web Page, if appropriate." Supplement with your own assessment activities. [Assessment Boundary: Assessment does not include the phases of meiosis or the biochemical mechanism of specific steps in the process.

(HS-LS3-1),(HS-LS3-2), Scale, Proportion, and Quantity• Algebraic thinking is used to examine scientific data and predict the effect of a change in one variable on another (e.g., linear growth vs. exponential growth). (HS-LS3-2),(HS-LS3-3). A. www.njctl.org 7th Grade PSI Inheritance and Variation of Traits Heredity Chapter Problems Mendelian Genetics Class Work 1. Heredity: Heredity may be defined as the transmission of characters from one generation to successive generations or from parents to their off spring. Environmental factors can also cause mutations in genes, and viable mutations are inherited. Non Mendelian Inheritance: Incomplete Dominance. Understand that in sexual reproduction, chromosomes can sometimes swap sections during the process of meiosis (cell division), thereby creating new genetic combinations and thus more genetic variation. Start studying Unit 3: Heredity - Inheritance and Variation of Traits. (HS-LS3-2)MathematicsMP.2 Reason abstractly and quantitatively. Author Last Name, First Name(s). ], HS-LS3-2. Genes are regions in the DNA that contain the instructions that code for the formation of proteins. Where do you get your traits from? Inheritance depicts the pathway of the genetic traits and its expression from one to another generation. Examples of Models (depicts the concept expressed in the reading):Ask students to look at the models and explain how each illustrates the concepts they read about. Textbook pages 4. The principal of independent assortment states that the inheritance pattern of one trait will not affect the inheritance pattern of another pair. The instructions for forming species’ characteristics are carried in DNA. NGSS Note: Think, question, entertain ideas. Puedes cambiar tus preferencias de publicidad en cualquier momento. Environmental factors also affect expression of traits, and hence affect the probability of occurrences of traits in a population. Citing for websites is different from citing from books, magazines and periodicals. Performance Expectations Students who demonstrate understanding can: HS-LS3-1. LS3.A: Inheritance of Traits • Many characteristics of organisms are inherited from their parents. Additional significant descriptive information. Title: Subtitle: Section of Page if appropriate. Contact. Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring. When you research information you must cite the reference. flow chart starting with the cell down to the gene and then to a physical trait.

Environmental as well as genetic variation and the relative dominance of each of the genes in a pair play an important role in how traits develop within an individual. Although DNA replication is tightly regulated and remarkably accurate, errors do occur and result in mutations, which are also a source of genetic variation. (HS-LS3-3).
