Genetics Unit Standards - First 4 of 8 Weeks - December
SB2. Obtain, evaluate, and communicate information to analyze how genetic information is expressed in cells.
a. Construct an explanation of how the structures of DNA and RNA lead to the expression of information within the cell via the processes of replication, transcription, and translation.
b. Construct an argument based on evidence to support the claim that inheritable genetic variations may result from:
· new genetic combinations through meiosis (crossing over, nondisjunction);
· non-lethal errors occurring during replication (insertions, deletions, substitutions); and/or
· heritable mutations caused by environmental factors (radiation, chemicals, and viruses).
c. Ask questions to gather and communicate information about the use and ethical considerations of biotechnology in forensics, medicine, and agriculture. (Clarification statement: The element is intended to include advancements in technology relating to economics and society such as advancements may include Genetically Modified Organisms.)
Genetics Unit Standards - last 4 of 8 Weeks - January
SB3. Obtain, evaluate, and communicate information to analyze how biological traits are passed on to successive generations.
a. Use Mendel’s laws (segregation and independent assortment) to ask questions and define problems that explain the role of meiosis in reproductive variability.
b. Use mathematical models to predict and explain patterns of inheritance. (Clarification statement: Students should be able to use Punnett squares (monohybrid and dihybrid crosses) and/or rules of probability, to analyze the following inheritance patterns: dominance, codominance, incomplete dominance.)
c. Construct an argument to support a claim about the relative advantages and disadvantages of sexual and asexual reproduction.
