2. A typical cell of any organism contains genetic instructions that specify its
traits. Those traits may be modified by environmental influences.
As a basis for understanding this concept, students know:
a. the differences between the life cycles and reproduction of sexual and
asexual organisms.
b. sexual reproduction produces offspring that inherit half their genes from
each parent.
c. an inherited trait can be determined by one or more genes.
d. plant and animal cells contain many thousands of different genes, and
typically have two copies of every gene. The two copies (or alleles) of the
gene may or may not be identical, and one may be dominant in determining
the phenotype while the other is recessive.
e. DNA is the genetic material of living organisms, and is located in the
chromosomes of each cell.
Instructional Resources/Materials: Optional: Prentice Hall 2008 Focus on Life Science text P.186 • Paper cutter or scissors to cut up cards. • Genetics vocabulary cards – printed (class set) Enough for each student (See card sort below) • Cut up cards, may be laminated for future use. Activity/Lesson: Each student takes a genetics vocabulary card and searches for the student with the matching definition. Once a match is found, students sit down together and write out definitions. These can be added to a yearlong vocabulary booklet. There are several ways to have students pair up. Students can work in pairs, search for their match or mix and match in table groups. Assessment: 1. Students write a summary using vocabulary words. 2. Oral check at the end of class “Who can give me a definition of …….” Page 1 of 5
