courtship behavior Flashcards
What is courtship behavior?
= essential for sucessful mating
= and for species recognition
What is a species?
= a group of similar organisms, that can breed to make fertile offspring
= species must reproduce and pass on advantageous alleles for the surivival of the species
=
What are courtship rituals?
= a sequence of actions which is unique to the species, this is how animals identify members of their own species to reproduce with
Which genders is more likely to do these rituals?
= males
= females obsevre the ritual and decide if they want to mate with the male
What do these rituals contain?
= sequence of dance moves
= sounds
= releae of pheromeomes
= display of feathers
= fighting
What is the importance of courtship rituals?
= ensure sucessful reproduction
= recognise their own species and opposite sex
= suncrhonises mating behaiour- indicates sexually mature and in season (releasing egg)- if they werent sexually mature feryile gametes are not made, if wont be sucessful reproduction- can mate and produce fertile offspring
How does courtship behaviour allow for the survival of offspring:
= form a pair bond-
= choose a strong and healthy mate
How can you study these rituals to determine how closley related diferent species are?
= the more similar a courtship ritual is beyweem 2 species that are different the more closley related the species are
What does a similar sequence show?
= courtship sequence is genetically determined so the more similar a species sequence is the more similar the DNA base sequencwe is
