bad luck in random assortment
agonistic behavior - ANS-fight or flight
social interactions
alleles - ANS-diff. forms of same gene
allelic - ANS-can occur b/n corresponding genes on homologous chromosomes
allelomimetric behavior - ANS-same species do the same thing @ same time bc they
follow

care-soliciting - ANS-=babies cry
characteristics of domestic animals - ANS-form groups
promiscuous
docile

habituation - ANS-responding without thinking
desensitization
heritability (h^2) - ANS-what part of an animal's phenotype is due to genetics and not
environment?
=portion of trait that will be passed on to the next generation
*varies by trait, 0 - .99
-> repro/survivability = no
-> growth traits = yes
