Resource summary
DNA and patterns of inheritance
DNA is a molecule arranged in a double helix spiral, and is our genetic structure
Chromosomes carry genes (pieces of information)
DNA is short for doexyribonucleic acid
Each human cell contains about 2m of DNA strands forming a double helix
The average human has 46 chromosomes
Genes contain thousands of bases. They control the development of inherited characteristics such as hair colour, eye colour and nose shape etc
They also control the production of hormones such as insulin
Each chromosome also contains mother and father genes
For example, if your father had blue eyes, and your mother brown, you would inherit one of these two
Similarly, this works for blood type, being able to roll you tongue, skin colour etc
A normal human cell contains 23 pairs of chromosomes
Genes are made of DNA
Male sex chromosomes are XY
Female sex chromosomes are XX
A dominant allele will always express it's characteristic
