Strand 3: Characteristic and Interactions of Living Organisms
3. There is a genetic basis for the transfer of biological characteristics from
one generation to the next through reproductive processes
Major Objectives IS Suggested Activities
These samples activities offer ideas and are not
Concept C: Chromosomes are components of cells
that occur in pairs and carry hereditary
information from one cell to daughter cells and
from parent to offspring during reproduction
Scope and Sequence – Reproduction and Heredity

Suggested Assessments
These samples assessments offer ideas and are not
meant to limit teacher or student resourcefulness
a. Identify chromosomes as cellular structures that
occur in pairs that carry hereditary information in
units called genes
b. Recognize that when asexual reproduction occurs,
the same genetic information found in the parent
cell is copied and passed on to each new daughter
cell(Assess only the concept – not the term or
process of mitosis)
R
W
a. Students will use models to demonstrate how
genetic material is transmitted and how gene
traits are expressed in offspring (1.3; 2.2)
b. Students will create a visual representation of
the molecular mechanisms that cause asexual
reproduction to result in identical offspring
and sexual reproduction to result in variation
in offspring (1.3; 2.1)
a. Students will demonstrate that chromosomes
and genes come in pairs and are composed of
many genes. Students will discuss how
genetic material is transmitted.
b. Students will use Punnett squares and
pedigree charts to demonstrate how single
gene traits are expressed in offspring.
c. Recognize that when sexual reproduction occurs,
genetic material from both parents is passed on
and combined to form the genetic code for the new
organism (Assess only the concept - not the term
orprocess of meiosis)
Concept D: There is heritable variation within
every species of organism
Scope and Sequence – Reproduction and Heredity
c. Students will organize data, information, and
ideas into a visual representation of the
patterns and relation-ships involved in the
chromosome contributions of gametes in
sexual reproduction (1.6; 1.7; 1.10; 2.1; 3.2;
4.6)
c. Students will use technology (DVD/computer
simulations) to visually demonstrate the
movement of chromosomes from parent to
daughter cells.
a. Recognize that when asexual reproduction occurs,
the daughter cell is identical to the parent cell
(assuming no change in the parent genes)
R
a. Students will use models to demonstrate how
genetic material is transmitted and how gene
traits are expressed in offspring (1.3; 2.2)
a. Students will use Punnett squares and
pedigree charts to demonstrate how single
gene traits are expressed in offspring.
b. Recognize that when sexual reproduction occurs,
the offspring is not identical to either parent due to
the combining of the different genetic codes
contained in each sex cell
R
b. Students will use student/teacher provided
examples of variations among siblings in a
family. (1.3, 4.6)
b. Students will investigate common genetic
traits among family members and compare
these traits by looking for them among their
classmates.
