reproductive strategy 

• the way an animal produces, sexual or asexual

• selective breeding and natural selection

sexual reproduction

• requires two mates

continuous variation 

• a range of variations in a trait usually in measurement

chromosome 

• a gene passed down from both parents

• a pair of each chromosome

domestic animal 

• animal in captivity

• relies on humans for care

• tamed and kept by humans

artificial selection 

• humans select breeding pairs to ensure offspring acquire desirable traits

• humans pick traits

selective breeding 

• humans pick breeding pairs to ensure offspring has desirable traits

natural selection 

• breeding pairs occur naturally

structural adaptation 

• physical adaptation to the species

generalist 

• species that has adapted to a general environment

  • general food source

  • can adapt to change

specialist
