It’s genetics,
Inheritance.
It’s genetics:
How traits are passed on

It’s genetics:
How traits are passed on
We each have
genes
Found on every
chromosome
and
They code for
traits
Your eyes are green
But his are grey and
mine are brown
All caused by genes
You have two
genes, one from
mom and one
from dad
They’re called
alleles
homozygous
Two of the same
and homozygous
is your name
You’re
heterozygous if
it’s one of each
heterozygous

It’s genetics:
How traits are passed on
Phenotype 
expression of
genes, what you
look like
These are your
traits
Genotype  the
genes that control
characteristics
On chromosomes
Dominance 
expressing one
trait over another
Recessive is
masked
Autosomes  they
do not determine
gender,
Like sex
chromosomes
