What are brains made up of?
Cells, which are made of proteins that are coded by DNA
DNA code serves as instructions for making...
Different kinds of proteins
What creates neuronal diversity?
The precise order and timing of gene expression
Overall, is the blueprint for a brain conserved across evolution?
Yes
What is a genotype?
Sequence of letters of your genome
What is a phenotype.
Measurable trait- height, weight, how high you can jump, blood type
What is epigenetics?
Environments can have its effects by altering gene expression
What is heritability?
How much of a phenotype is inherited, presumably due to its genetic factors
What do twin studies show about the heritability of phenotypes?
Many phenotypes are somewhat inheritable & more inheritable in monozygotic vs dizygotic twins
What is heritability a fraught topic?
You can’t make accurate predictions on phenotypes based on genotypes
Why can’t you make accurate predictions about a phenotype based on genotype?
Because you don’t know the environment someone is in
