this is a tree that groups relationships between different life forms on earth, they are separated by the presence of the nucleus

what is family homididi
this shows the closeness of humans and chimpanzees in genetics.
2 of 22
what is the brain size theory
suggestion that as humans evolved, their brains got larger, which leads to more intellectual development
3 of 22
who developed the encephalitic quotient
jensson, 1973
4 of 22
what is the encephalitic quotient
takes into account brain:body weight ratio, and places it along a prediction quotient which places humans as the highest
5 of 22
what is LHS
LHS is a short DNA sequence that has a double helix. these are base pairs.
6 of 22
what are the four nucleaide types
adenine, thymonine, guarine, cytosine
7 of 22
what is RHS
the DNA is in 23 pairs, one comes from the mother, and one comes from the father. the last pair is either ** or XY. these pairs are homologus, meaning they arent identical.
8 of 22
what is an allele
these are variations in the functions of genes
9 of 22
what is protein production
this is when strands of DNA separate, which exposes the base pairs, which means RNA can transcript it. it sends a message to the mRNA, which is translated into amino acid. proteins are chains of amino acids.

what is mitosis
cell divides creating two identical daughter cells
11 of 22
what is miosis
cell divides creating four different daughter cells
12 of 22
what is a genotype
a persons genetic makeup
13 of 22
what is a phenotype
this is the expressed characteristic of the genotype
14 of 22
what is PKU
this is a metabolic disorder of the PHE metabolism that can cause brain damage, as well as abnormality of PAH gene on chromosone 12. both parents must have the PKU allelle.
15 of 22
what is downs syndrome
this is when people have an extra copy of the 21st chromosome. the chromosome produces certain characteristics such as reduced intellectual capacity, visual problems, short stature, ect
16 of 22
what is huntingtons disease
a fatal neurogenic disease, from the dominant mutation of the Huntington gene on chromosome 4. this is important in normal nerve function.
17 of 22
what is behavioural genetics
defined as the study of genetic influences on behaviour
18 of 22
what did tyson do with his rats
1934, rewarded rats with food, errors were counted for maze. breeded those that made most and least errors. found significant differences between performance of better rats.
19 of 22
what did amit and smith do
1992, found out animals alcohol consumption can be selectively breeded for a gene for alcoholism
20 of 22
what did cooper and zubeck do
looked at the effect of environment on rats. either restricted or enriched cages. restricted made way more errors.
21 of 22
what is genetic analysis
lots of criticism as twins are also often raised in the same environment . however, in IQ little difference so suggests theres a biological element even without shared enviornment
