In the DNA are genes that determine
who you are
Genes are found in DNA, which are
found in chromosomes, which are
found in a cell’s nucleus.

TO FIND SOMONES GENES THIS IS
WHAT YOU MUST DO
Each trait of an organism is
determined by a gene.
TRUE
known
TRUE
Each gene gives us a different trait
from either parent
Humans have 46 chromosomes, half
come from each parent.
TRUE
GUESS
TRUE
We get 23 chromosomes from each
parent
The cells in a person’s eyes only
have the eye color gene, all other
cells do not have that gene.
FALSE
GUESS
TRUE
This is because these cells are only
relevant to traits that relate to their to
them.
Only some organism’s cells contain
chromosomes, genes, and DNA.
TRUE
known
FALSE
All organisms have DNA,
CHROMOSONES, and GENES
We have two genes for each trait in
our cells but each gene might have
different instructions for the same
trait.

NO IDEA WHATSO EVER
TRUE
I chose this because we do have two
genes for each trait. One from my
mom and one from my dad. And these
genes might have different
The instructions that determine an
organism’s traits are found in an
organism’s DNA.

Genes contain information that can
be passed from parent to offspring.

TRUE
Inherited characteristics are called
traits and are passed from parent to
offspring.

instructions because if it is for eye
color my mom might have green eyes,
so the gene’s instructions’ is to have
green eyes, and my dad’s might be
different.
When an egg and sperm are connected
together the genes from the sperm
and egg are copied exactly to the
offspring. This means that the
information from the genes inside the
sperm and egg are also going to be
passed to the offspring.
I chose this because we inherit two
genes from our mother and father
combined to go under the category of
the “hair color trait”.
Reproduction is the whole reason why
we inherit traits. Without reproduction
the sperm and egg wouldn’t create an
offspring with a copy of the sperm’s 23
chromosomes, and the egg wouldn’t
create a copy of it’s 23 chromosomes.
