|
4.1.2 |
Define gene, allele
and genome. |
|
4.3.1 |
Define genotype,
phenotype, dominant allele, recessive allele,
codominant alleles, locus, homozygous,
heterozygous, carrier and test cross. |
|
4.3.2 |
Determine the
genotypes and phenotypes of the offspring of a
monohybrid cross using a Punnett grid. |
|
4.3.3 |
State that some genes
have more than two alleles (multiple alleles). |
|
4.3.4 |
Describe ABO blood
groups as an example of codominance and multiple
alleles. |
|
4.3.5 |
Explain how the sex
chromosomes control gender by referring to the
inheritance of X and Y chromosomes in humans. |
|
4.3.6 |
State that some genes
are present on the X chromosome and absent from
the shorter Y chromosome in humans. |
|
4.3.7 |
Define sex linkage. |
|
4.3.8 |
Describe the
inheritance of colour blindness and hemophilia
as examples of sex linkage. |
|
4.3.9 |
State that a human
female can be homozygous or heterozygous with
respect to sex-linked genes. |
|
4.3.10 |
Explain that female
carriers are heterozygous for X-linked recessive
alleles. |
|
4.3.11 |
Predict the genotypic
and phenotypic ratios of offspring of monohybrid
crosses involving any of the above patterns of
inheritance. |
|
10.2.2 |
Distinguish between
autosomes and sex chromosomes. |
|
10.2.1 |
Calculate and predict
the genotypic and phenotypic ratio of offspring
of dihybrid crosses involving unlinked autosomal
genes. |
|
10.3.1 |
Define polygenic
inheritance. |
|
10.3.2 |
Explain that
polygenic inheritance can contribute to
continuous variation using two examples, one of
which must be human skin colour. |
|
4.3.12 |
Deduce the genotypes
and phenotypes of individuals in pedigree
charts. |
