Inheritance
DNA
-
The structure of DNA was discovered by Rosalind Franklin, James Watson
and Francis Crick.
-
There is a code within DNA called the genetic code.
This code controls the production of thousands of
proteins that make up the human body.
-
Mendelian
inheritance
-
Gregor Mendel is known as ‘the father of genetics’. He carried out
research to explain how traits are passed from parent to
offspring.
Non-inherited traits do not involve genes, for example learning a
foreign language.
Inherited traits do involve genes, for example eye colour.

Chromosomes and genes
-
Genes are lengths of DNA along a
chromosome. Each gene controls the
production of a particular protein.
We have two genes for each trait: one
comes from the mother and one from the
father. Each member of the pair of genes is
located on the same place in the partner
chromosome.
Environment can affect the outcomes of
some genes. For example, if someone has
the genes to grow tall but is malnourished,
they may never grow as tall.
