(1/12/15 and 1/15/15)
Standard: LS3.B Variation of Traits
In sexual reproductions, chromosomes can sometimes swap sections during the process of meiosis (cell division), thereby creating new genetic combinations and thus more genetic variation. Although DNA replication is tightly regulated and remarkably accurate, errors do occur and result in mutations, which are also a source of genetic variation, Environmental factors can also cause mutations in genes and viable mutations are inherited (HS-LS3-2)
Objective: To understand the process of meiosis and how it can produce variations among a population.
Anticipatory Set: Brief discussion on Mitosis as a refresher. Brought up concepts such as chromosomes, and alleles.
Guided Practice: Students read the handout which was a copy of a section from the book. Students then answered the vocabulary questions and the big picture questions from the end of the section. Students then completed a supplemental worksheet that referenced information from the section of the book.
Closure: Students handed in worksheets and answers to section questions which are to be graded.
