These are dominoes. Cut each out. They join into a circle when matched correctly.
allele
The process in which
a male gamete and
a female gamete
join together
heterozygous
A person who carries
a particular allele but
it is not expressed
fertilisation
A feature of an
organism that is passed
on from one generation
to another eg. hair
colour, eye colour
carrier
The alleles are the
same eg. BB or bb
characteristic
The sex cells of
an organism
homozygous
Made up of DNA and
contains genes
gametes
Pollen is transferred
from the anther of one
plant to the stigma of
another plant.
chromosome
Refers to the way in
which characteristics
are passed on from one
generation to another
cross-pollination
Part of a chromosome
that codes for a
particular
characteristic such as
eye colour.
inheritance
Complex molecules
that form genes
gene
An allele that is
always expressed if
it is present
DNA
Cell division to
produce gametes
dominant
allele
The way in which the
alleles are present eg.
BB or Bb or bb
meiosis
A female gamete in
animals
genotype
Cell division to
produce cells with
the same number of
chromosomes
egg
Divergence in the
characteristics of an
organism from the
species or population
norm or average
mitosis
The homologous
chromosomes of a male
variation
The part of the cell
containing nuclear
material
XY
The way in which the
alleles are expressed
eg. blue eyes or
brown eyes
nucleus
The homologous
chromosomes of a
female
phenotype
In animals, female
gametes are produced
here
XX
The male gamete
in plants
ovaries
Two copies of this
allele must be present
for it to be expressed
pollen
In animals, male
gametes are produced
here
recessive
allele
Copying of the
chromosomes
testes
A male gamete
in animals
replication
The cell that forms in
the process of
fertilisation
sperm
An individual grown
from a single body
cell of its parent
and genetically
identical to it
zygote
The study of
inheritance
clone
A pair of chromosomes
with identical genes
genetics
The alleles are
different
homologous pair
An alternative form of
a gene eg. B or b
