Number of different alleles of a gene in a population 1 of 14 What is evolution? Change in allele frequence overtime 2 of 14 What is a species? Organisms that are same species that can breed to produce fertile offspring 3 of 14 What does courtship behaviour do? Increase chance of successful mating 4 of 14 How does courship behaviour work? Allow species to recognise each other, stimulate the release of gametes, recognise the opposite sex, indicate sexual maturity 5 of 14 What is Phylogenetic classification? Arranging species into groups based on their evolutionary origin 6 of 14 what is hierarchy? Small groups within bigger groups with no overlap between groups 7 of 14 how do you name an organism? First write it's genus, then its species. First letter capital in genus. Underline 8 of 14 What is a population? All the organisms of one species in a habitat 9 of 14 What is a community? All of the population of all the species in a habitat 10 of 14 What is biodiversity? The variety of species in an area 11 of 14 What is species richness? The number of different species in an area 12 of 14 What is index of diversity? Describes the relationship between number of species in COMMUNITY AND NUMBER OF INDIVIDULAS OF EACH SPECIES 13 of 14 What do I need to calculate index of diversity? Totals number of organisms of all species, Total number of organisms of each species 14 of 14
