Questions involving with DNAAA

There's some key definitions you need to understand:

The humans genome is a set of genetic information encoded in 46 chromosomes

Chromosomes are made of DNA (Deoxyribonucleic Acid) inherited from parents (sperm contains one chromosome, oocyte contains another chromosome, when fertilization occurs the chromosomes create a full genome)

DNA name given to the long double helical structure because of it's composition (Deoxyribonucleic Acid) and is split up into areas called genes it's these genes that code for specific phenotypes (i.e. physical characteristics; hair colour, height, skin colour, blood type, predispositions to some diseases).

There is a process where some genes are 'turned on' and others 'turned off', or express at different levels, and some are more dominant then others, and mutations can occur creating alleles (variant form of genes) which is why we get a range of phenotypes in humans and we don't look like exact copies on our parents.
