identical twins that come from one split fertilised egg which splits and forms into two eggs - genetically identical

Question 2

what are dizygotic twins?

weissman et al (2005)

Question 5

what is a genome?

Answer 5

the complete set of genetic information in an organism - provides all the information the organism requires to function

Question 6

what is evolution?

Answer 6

the change in heritable characteristics of biological populations over successive generations - passed down during reproduction

Question 7

what are epigenetics?

Answer 7

the study of changes in organisms caused by genetic modification of gene expression rather than the altercation of the genetic code itself

Question 8

human mating behaviour
