What do our parents have to do with our DNA?

Why do we have chromosomes
Well, our parents will 'mate' (sexual reproduction) which will produce two gametes (reproductive cells) (male gamete=sperm, female gamete=egg) and then a zygote (a single cell that forms you) is formed, and as soon as the zygote forms, the sperm and the egg's chromosomes are mixed with each other. That's how you get your DNA and that's how your parents are involved in making you.

Genes
The four codings
A-Adenine (can only go with Thiamine)
T-Thiamine(can only go with Adenine)
C-Cytosine(can only go with Guanine)
G-Guanine(can only go with Cytosine)
These four chemicals compose your entire genetic code.
