species and taxonomy Flashcards
1
Q
define species
A
2 organisms that are able to breed and produce fertile offspring
2
Q
define fertile
A
able to reproduce and have offspring
3
Q
explain the similarities between 2 robins that have the same genes
A
physically similar
biochemically similar
behaviour similar
4
Q
define courtship behaviour
A
ensures successful mating as it allows members of the same species to recognise each other
5
Q
if the species are more closely related what does this mean in terms of courtship behaviour
A
more closely related = more similar courtship behaviour
6
Q
how does courtship behaviour increase the probability of successful mating
A
- synchronise mating and release of gametes
- recognise mate of opposite sex
- recognise/attract members of the same species
- identify a mate that is sexually mature and therefore capable to breed
- form a pair bond to raise offspring
