Genes and Chromosomes Justified True or False Worksheet
Statement
The instructions that determine
an organism’s traits are found
in an organism’s DNA.
PRE
True or
False
TRUE
PRE
JustificationWhy did you choose T or F?
Because in our last unit we
learned about DNA and I know
that it’s like an encyclopedia. All
information is in it.
I Guessed
POST
True or
False
TRUE
POST
JustificationWhy did you choose T or F?
They are found in the genes,
which are pieces of DNA.
TRUE
We learned this in class and on
the website activity.
We learned from the video on
our homework that genes are in
DNA which are found in
chromosomes which are found in
a nucleus of a cell.
The traits are found in a gene,
which are determined from the
parents. So technically yes.
Genes are found in DNA,
which are found in
chromosomes, which are
found in a cell’s nucleus.
TRUE
Each trait of an organism is
determined by a gene.
TRUE
The DNA is the instructions for an
organism are found in a gene.
The gene is the cell for the DNA
like the epithelial cells for skin.
TRUE
Humans have 46
chromosomes, half come from
each parent.
FALSE
I guessed
TRUE
We learned it in class. Plus I
thought it meant in the entire
body not each cell.
The cells in a person’s eyes
only have the eye color gene,
all other cells do not have that
gene.
FALSE
I guessed
FALSE
Each cell has every gene but the
cell only uses the traits that are
relevant to that particular cell.

Only some organism’s cells
contain chromosomes, genes,
and DNA.
FALSE
Didn’t sound right. Every single
cell has genes, chromosomes,
and DNA. How would it now
what to be?
(what type of cell)
I guessed. PLUS
I think you get a gene from both
parents for everything but the
body only reads one of them.
FALSE
All organisms cells contain
chromosomes, genes, and DNA.
It just depends on how many the
organisms have.
We have two genes for each
trait in our cells but each gene
might have different
instructions for the same trait.
TRUE
TRUE
The mother might have green
eyes and the father might have
brown. So both traits are given to
the child so that’s why there’s 2
and they might be different.
They get passed from the process
of heredity and genes contain
the traits that are passed to you
that tell whether you get your
dad or mom’s eyes.
They are found in genes.
Genes contain information that
can be passed from parent to
offspring.
TRUE
That’s how you become who you TRUE
are.
Inherited characteristics are
called traits and are passed
from parent to offspring.
FALSE
I guessed
TRUE
Reproduction does not play a
role in inheriting traits.
FALSE
I can’t put it into words.
FALSE
That is the 1st step in the whole
process. Without that their would
be nothing.
Reproduction helps to inherit the
traits because reproduction
passes genes to the offspring.
And inside genes there are traits.
