About This Lesson

This unit plan is designed to introduce students to the topics of DNA replication, Heredity, genentics, and mitosis. It takes students through these topics including a hook, direct instruction, inquiry based learning, and many visual aids. The allotted time is somewhat fast so students who are ELs, SN, or struggling may need some more time to get through each lesson or additional resources to help build understanding.


Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.
Students know how mutations in the DNA sequence of a gene may or may not affect the expression of the gene or the sequence of amino acids in an encoded protein.
Students know the genetic basis for Mendel's laws of segregation and independent assortment.
Students know how to predict possible combinations of alleles in a zygote from the genetic makeup of the parents.
Students know how to predict the probable outcome of phenotypes in a genetic cross from the genotypes of the parents and mode of inheritance (autosomal or X-linked, dominant or recessive).
Students know new mutations are constantly being generated in a gene pool.
Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.
Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.
