Learning outcomes:
1 I can describe the relationship among chromosomes, genes and DNA, and their role
in storing genetic information.

 Each cell __________________.
To be able to fit it all in cells, they
are rolled up together in what we
call :
o Chromosomes.
 Every human
contains ______
____________:
 Different living organisms have different quantities of
chromosomes.
 These
chromosome
s are in
pairs.

A single gene is an uninterrupted segment of DNA, which
contains the ____________________________ for the
organism





Genes are located in
the chromosomes
Each chromosome
has numerous gene
locations
Genes come in ____
Both genes in a pair
carry DNA
instructions for the
same thing
Specific characteristic
genes occupy

matching locations on the two chromosomes
__________________________________________
__________________________________________
Offspring inherit genes from both parents. The genes exist in an array
of possible forms that differ as to their exact DNA sequence.

These variations in forms are called _______________.

The ____________________ of the chromosome pair is what
makes the variation possible - combining the different
variations of different characteristics to create a unique
variation.
