I can:
Give some examples of variation including flower colour in primrose
plants and tail length in squirrels

State that sexual reproduction involves combining genes from two
parents

State that this process contributes to variation within a species.

Explain that discrete variation is where a characteristic falls into
distinct groups, whereas continuous variation is where a characteristic
can have any value in a range.

State that single gene traits are controlled by one gene and show
discrete variation.

Give examples of single gene traits including flower colour and blood
type.

State that polygenic traits are controlled by many genes and show
continuous variation.

Give examples of polygenic traits including height and eye colour.

State that dominant genes always show up in the appearance of and
organism, even if there is only one copy present in the gene pair.

Identify dominant and recessive traits. For example, if a flower has
one tall gene and one dwarf gene and appears tall, I understand that
the tall gene is dominant, and the dwarf gene recessive.

State that phenotype describes the appearance of an organism.

Give examples of phenotypes of one characteristic. For example, eye
colour in humans (different phenotypes may be blue, brown or green.)

Assign a genotype to an organism based on the knowledge that
dominant characteristics are given capital letters, and recessive
characteristics are given lower case letters.

Explain that homozygous individuals have two matching alleles of one
gene. (e.g. HH or hh)

State that heterozygous individuals have two different alleles of one
gene. (e.g. Hh)

Work out the genotype of the gametes that will be produced by an
individual.

Use a punnet Square to work out the possible genotypes of the
offspring in a monohybrid cross.

Identify individuals in a pedigree chart using the key provided.

Explain that a carrier is a person who has one copy of a disease allele
but is not affected by the disease.

State that carriers and those at risk of passing on a genetic disorder
to their offspring may receive genetic counselling.
