What is the primary criterion for defining a species?
individuals that share the same habitat
individuals that have similar physical characteristics
individuals that are capable of interbreeding and producing fertile offspring
individuals with identical genetic makeup
|
Which of the following factors contribute to the emergence of new species?
(Select all that apply)

|
What is the most likely consequence of postzygotic reproductive barriers?
the lack of gene flow between populations
the prevention of fertilisation and zygote formation
the formation of infertile or non-viable hybrid offspring
the formation of viable, fertile hybrid offspring
|
What is the most accurate description of genetic isolation?
the lack of gene flow between populations
the isolation of genes within a single individual

What is the main consequence of sympatric speciation?
the prevention of speciation
the formation of separate species within the same geographical location
