The student will investigate and understand that organisms reproduce and transmit genetic information to new generations. Key concepts include
a) the role of DNA;
b) the function of genes and chromosomes;
c) genotypes and phenotypes;
d) factors affecting the expression of traits;
e) characteristics that can and cannot be inherited;
f) genetic engineering and its applications; and
g) historical contributions and significance of discoveries related to genetics.
Overview / Key Concepts
DNA is a
double helix molecule.
are expressed through genes can be inherited. Characteristics that are
acquired through environmental influences, such as injuries or practiced
skills, cannot be inherited.
• In genetic engineering, the genetic code is manipulated to obtain a desired product.
• Genetic engineering has numerous practical applications in medicine, agriculture, and biology.
• A series of contributions and discoveries led to the current level of genetic science.
Knowledge & Skills
the appearance of DNA as double helix in shape.
• explain that DNA contains coded instructions that store and pass on genetic information from one generation to the next.
• demonstrate variation within a single genetic trait.
• explain the necessity of DNA replication for the continuity of life.
• differentiate between characteristics that can be inherited and those that cannot be inherited.
between dominant and recessive traits.
• distinguish between genotype and phenotype.
• use Punnett squares to predict the possible combinations of inherited factors resulting from single trait crosses.
• identify aspects of genetic engineering and supply examples of applications. Evaluate the examples for possible controversial aspects.
• describe the contributions of Mendel, Franklin, and Watson and Crick to our basic understanding of genetics
