7th+Grade+Genetics


 * Established Goals: **

 (11) Organisms and environments. The student knows that populations and species demonstrate variation and inherit many of their unique traits through gradual processes over many generations. The student is expected to:  (C) identify some changes in genetic traits that have occurred over several generations through natural selection and selective breeding such as the Galapagos Medium Ground Finch (//Geospiza fortis//) or domestic animals. (14) Organisms and environments. The student knows that reproduction is a characteristic of living organisms and that the instructions for traits are governed in the genetic material. The student is expected to: (A) define heredity as the passage of genetic instructions from one generation to the next generation; (B) compare the results of uniform or diverse offspring from sexual reproduction or asexual reproduction; and (C) recognize that inherited traits of individuals are governed in the genetic material found in the genes within chromosomes in the nucleus.
