1. The genetic composition of
an organism is called the
BLANK and any change to it
is called a BLANK. The
actual appearance of an
organism is called the
BLANK.

1. The genetic composition of
an organism is called the
genotype and any change to
it is called a mutation. The
actual appearance of an
organism is called the
phenotype.

2. A gene is a sequence of BLANK
along a piece of DNA that
determines a single
characteristic of an organism.
It does this by coding for
particular BLANK that make up
the enzymes needed in a
biochemical pathway.

2. A gene is a sequence of
nucleotides along a piece of
DNA that determines a single
characteristic of an organism.
It does this by coding for
particular polypeptides that
make up the enzymes needed in
a biochemical pathway.

3. The position of an allele on a
chromosome is called the
BLANK. Each gene has two
or more different forms
called BLANK.

3. The position of an allele on a
chromosome is called the
locus. Each gene has two or
more different forms called
alleles.

4. If two alleles are the same
they are said to be BLANK.
If they are different, they
are said to be BLANK.

4. If two alleles are the same
they are said to be
homozygous. If they are
different, they are said to
be heterozygous.

5. An allele which needs two
copies to be expressed is
known as BLANK. If only one
allele is needed to be
expressed it is said to be
BLANK. Two alleles are called
BLANK when they contribute
equally to the phenotype.

5. An allele which needs two
copies to be expressed is
known as recessive. If only
one allele is needed to be
expressed it is said to be
dominant. Two alleles are
called codominant when they
contribute equally to the
phenotype.
