How are genes passed on?
What carries the genetic information?
Information stored in our DNA
DNA
Deoxyribonucleic acid
Looks like twisted ladder
Dubble helix
Step of ladder made of the bases
There are four bases
Adenine (A)
Thymine (T)
Guanine (G)
Cytosine (C)
Order of different steps produces a code of letters
Code severs as building instructions
For the cel to make proteins
Gene
Specific protein builder
Own function
Chromosomes
What influence do genes have?
How our body looks and functions
Combination genes
Our enviorment
Our lifestyle
particular characteristic or trait is due to a specific gene does not happen. Genes work together.
genes come in pairs
One is inherited from the father, and one from the mother
may be slightly different to each other.
Bloodgroup
Gen A + Gen A = Bloodgroup A
Gen A + Gen B = Bloodgroup AB
Why do we have two versions of most genes?
One from you mother and one from your father.
Advantage
On gen that cause a disease
The health gen can get rid of disease
Mixing the gens can create new condition for gens.
Future generations
Better adapt to environment conditions
Protect them from diseases
What do the terms “dominant” and “recessive” mean?
Dominant
Stronger gene
Decides trait
Recessive
Weaker gene
Sometimes there are two Recessive genes
Bloodgroup
Recessive + recessive = Bloodgroep O
same traits and characteristics don’t necessarily come from identical genetic information
