• what is meant by a gene locus

  this is the location of a gene o other DNA sequence on a chromosome
• what is selection pressure

  this is an environmental factor which can alter the allele frequencies of the alleles .
• what will affect breeding success

  inter and intraspecific competition
• what selective agents may exert selection pressure

  climate,human impact, breeding site availability and availability of food
• what are selective agencies


  these are factors that exert pressure for select advantages
• what is meant by a animal with a selective advantage

  these are animals with a specific phenotype that will help them survive a specific pressure.
• what is meant by an animal that is selective against
