Genes and Chromosomes Justified True or False Worksheet
Statement
Genes are found in DNA, which are
found in chromosomes, which are
found in a cell’s nucleus.
True
PRE
JustificationWhy did you choose T or F?
Traits can be found in your
DNA because the DNA comes from
your parents and that is where you
inherit your traits from.
I am just guessing!!!
Each trait of an organism is
determined by a gene.
False
I am just guessing!!!
True
Humans have 46 chromosomes, half
come from each parent.
False
Not exactly half of your traits come
from your mother and father.
True
The cells in a person’s eyes only
have the eye color gene, all other
cells do not have that gene.
True
Another part of the body would not
have the color of your mother’s eye
for example.
False
The other cells do have the eye color
gene.
Only some organism’s cells contain
chromosomes, genes, and DNA.
False
I am just guessing!!!
False
EVERY organism’s cells contain
chromosomes, genes, and DNA.
We have two genes for each trait in
our cells but each gene might have
different instructions for the same
trait.
True
I am just guessing!!!
True
The genes are the same type but they
might contain different information
and for example, one eye gene can
hold the color blue while the other
The instructions that determine an
organism’s traits are found in an
organism’s DNA.

JustificationWhy did you choose T or F?
What controls the traits are called
genes and these are found in your
DNA.
False
Genes are found in chromosomes,
which are found in DNA, which are
found in the cell’s nucleus.
You get 2 of the same types of genes
(one from mother and 1 from father)
but only 1 will be used.
You get 23 from your mother and 23
from your father and this equals 46.

Genes contain information that can
be passed from parent to offspring.
True
Genes can be passed down from your
parents that contain information.
True
Inherited characteristics are called
traits and are passed from parent to
offspring.
True
You may have a trait that one of your
parents might have.
True
Reproduction does not play a role in
inheriting traits.
False
Without reproduction we could not
inherit traits.
False
holds green but only one of these
genes will be used.
Genes hold information that can be
passed to you and this affects the
traits that you get.
In reproduction the inherited
characteristics are passed to you and
these are called traits and could be
similar from your mother or father.
Without reproduction we could not
inherit traits.
