Document Summary

Hereditary material in humans and almost all other organisms. Nearly every cell in a human body has the same dna| Contain genetic blueprint: each gene codes for a protein product, dna->rna->protein. Brown hair, blonde hair) are a alternative form of gene that produce different characteristics. Genes contain bases, carry codes for protein manufacture. 2 copies of a gene, one from each parent: dominant genes expressed if only one copy 9 (bb, recessive only express if there is 2 copies (bb) Humans have 25000 genes, mapped every single one of them.

Heritability coefficient extent to which variation in a specific group can be attributed to genetic factors is estimated statistically. The more the gene co-occurs = possible genetic contribution. More similar regardless of environment, even when reared apart. Separated at birth, some genetic traits and personality traits were similar.
