Inheritance dominoes
Punnett square
diagram
START:
People who are
heterozygous for
the cystic fibrosis
allele
carriers
Can be used to show
the inheritance of
certain traits
family trees
Occurs in a
developing organism
when cells begin to
become specialised
cell
differentiation
A haploid
reproductive cell
such as sperm or
pollen
gamete
This is created, in
part, by sexual
reproduction as each
gamete is different
variation
Method of
reproduction used by
malarial parasites in
human red blood
cells
asexual
reproduction
Found in plants and
animals. They are
undifferentiated cells
stem cells
Except for red blood
cells, human body
cells contain 46 of
these?
chromosomes
First carried out by
Gregor Mendel in his
studies of sweet pea
plants
genetic
crosses
Involves three stages
and results in the
formation of two
identical cells
cell cycle
Offspring which are
genetically identical
to the parent
clone
Formed when sperm
and egg fuse together
zygote
Each one codes for a
different protein
gene
Different versions of
the same gene
allele
When the alleles of a
particular gene are
different
heterozygous
This form of cell
division produces
genetically identical
daughter cells

Inheritance dominoes
mitosis
A feature or trait
controlled by one or
more genes
characteristic
This form of cell
division produces sex
cells
meiosis
These alleles are
expressed in the
phenotype
dominant
The physical
structure of DNA
double helix
A sudden change in
the structure of a
gene
mutation
These are released
by fungi when
reproducing asexually
spores
The alleles for a
characteristic are the
same
homozygous
All the genetic
material of an
organism including
mitochondrial DNA
genome
This genetic disorder
affects cell
membranes and is
caused by a recessive
allele
cystic fibrosis
Method of asexual
reproduction found in
daffodils
bulb division
A polymer molecule
which carries the
genetic instructions
of an organism
DNA
The set of genes
which code for a
particular trait
genotype
These alleles are only
expressed when
inherited from both
parents
recessive
This means having
extra fingers of toes,
and is caused by a
dominant allele
polydactyly
Is what a particular
trait actually looks
like i.e. how it is
expressed
phenotype
Grid used to show the
outcome of genetic
crosses

Teaching notes
The cards cover key definitions from section 4.6.1 of AQA GCSE Biology specification –
reproduction but can be used with for other specifications.
There are 32 cards, allowing it to be used with a whole class. Cut up the domino cards before
the lesson. The activity could also be done individually, in pairs or in small groups to produce a
complete ordered set of cards.
