and animals

conditions
- changes in chemical
conditions
- competition for resources
- how the theory of evolution is
supported
- palaeontology
- biogeography
- comparative anatomy
- comparative embryology
- biochemistry
- Darwin/Wallace’s theory of
evolution by natural selection
- divergent
evolution
- convergent
evolution
- Gregor
Mendel’s
experiments
- experiments carried out
- experimental techniques led to his
success
- outcomes of monohybrid
crosses involving simple
dominance
- homozygous and
heterozygous
genotypes
- allele and
gene
- dominant and
recessive alleles and
phenotype
- importance of Mendel’s
work was not recognised
until some time after it
was published
- Inheritance
- Sutton and Boveri
and the
importance of
chromosomes
- chemical nature of chromosomes and
genes
- DNA is a double-stranded molecule twisted into a
helix with each strand comprised of a
sugar-phosphate backbone and attached bases –
adenine (A), thymine (T), cytosine (C) and guanine
(G) – connected to a complementary strand by
pairing the bases, A-T and G-C
- relationship between the structure and
behaviour of chromosomes during meiosis
and the inheritance of genes
- role of gamete formation and sexual
reproduction in variability of
offspring
- inheritance of
sex-linked genes,
and alleles that
exhibit
co-dominance and
do not produce
simple Mendelian
ratios
- work of Morgan that
led to the
understanding of sex
linkage
- relationship
between
homozygous
and
heterozygous
genotypes and
the resulting
phenotypes in
co-domanance
- environmental effects on
the expression of a gene
- DNA
- process of DNA replication
+ significance
- process by which DNA controls
the production of polypeptides
- relationship between
proteins and polypeptides
- mutations in DNA may lead to
the generation of new alleles
- evidence for the mutagenic
nature of radiation
- source of variation in
organisms has provided
support for Darwin’s
theory of evolution by
natural selection
- concept of punctuated
equilibrium in evolution +
how it differs from the
gradual process proposed
by Darwin
- reproductive
technologies
and genetic
engineering
- current reproductive techniques may
alter the genetic composition of a population
- artificial insemination
- artificial pollination
- cloning
- processes used to produce
transgenic species
- the potential impact of the use of
reproduction technologies on the
genetic diversity of species
