protein determining feature.
Base sequence reference omitted.
DNA link with genes/alleles not shown.
Two Achievement opportunities gained
to give an overall Achievement grade
for Question One.

Gamete description
lacking reference
to sex cell.
Description lacking
reference to genotype/
different alleles.
Reference to chromosome separation.
Recognition that variation will
ensure species not eliminated in
environmental change.
Two Merit opportunities gained to give an
overall Merit grade for Question Two.
Dominant allele defined.
Punnett square shows
link to Generation 2.
Evidence linked with Generation 1 parents.
Punnett square and probability determined.
Three Merit opportunities reached to give
an overall Merit grade for Question Three.

Two Achievement opportunities
gained to give an overall grade of
Achievement for Question Four.
High Merit
Defined.
Bases, proteins linked with phenotype.
Link not established between
bases and genes/alleles.
Two Achievement opportunities gained
to reache an overall Achievement grade
for Question One.
Definition of
gametes
acceptable.
Linkage present between
number of chromosomes in
gametes and fertilised cells.
Non-specific statement.
Account of chromosome separation.
Linkage between environmental change
and variation enabling survival.
Two Merit opportunities gained to given
an overall Merit grade for Question Two.
Definition covers expression.
Reasoning links
Generation 2 and
offspring.
Explains how Generation
3 offspring must receive
recessive allele from A.
Punnett square correctly completed, as is probability
and contains reference to sample size.
Two Merit opportunities gained and one excellence opportunity
to give an overall Excellence grade for Question Three.
Described as DNA change.
Recognises that skin cells are
not linked with meiosis and
gametes.
Not discussed.
Recognises larger leaved plants of species A will be
adopted to survive and can reproduce.
Two Merit opportunities gained to give an overall
Merit grade for Question Three.
