C4 Genes, Evolution, Perception Flashcards
Evolution
change in heritable traits in a population over time
Behaviour
an organisms actions in response to some stimulus
Gene
the basic unit of heredity
from parents to offsprings
Genotype
genetic makeup
Phenotype
observable charcteristics
Epigenetics
lasting changes in gene expression during development that is not caused by genes themselves
external, environmental factors
Gene Knockout Process
alter specific genes so it cannot function
multiple genes and systems can be involved
Behaviour Genetics
study of how genetic and environmental components changes in behavior
CRISPR
Heredity of Intelligence
50~70% inherited by parents
Reaction Range
range of the possibilities that the genetic code allows, environmental effects determine where to fall in the range
Natural Selection
the process by which evolution occurs
Parental Investment
time, effort, risk, and energy associated with caring successfully for offspring
Humans invest a lot- a small number of offspring
little care- a large number of offspring
Cooperation
one individual helps another and gains some advantage
Altruism
one individual helps another and there’s costs involved
Kin selection theory
animals are more likely to behave altruistically toward relatives
