Group of answer choices zygote mortality hybrid sterility temporal isolation F2 fitnessarrow_forwardHybrid breakdown refers to which situation? Group of answer choices Two species can hybridize but their offspring do not develop fully or are frail and will not survive to reproduce. Two species can hybridize but their offspring are sterile. None of the above Two species can hybridize and their offspring are ok and can have offspring, but the next generation are more likely to die or will be sterile.

- Two sympatric species of wildflowers grow the same habitat but hybrids are extremely rare in nature despite the facts that viable hybrids can easily be produced in the lab. The rarity of hybrids is hypothesized to be the consequence of the difference in the blooming season because one species blooms in April while the other blooms in June. This hypothesis is referring to what type of reproductive isolation? Question 6 options: Mechanical isolation Behavioural isolation Temporal isolation Habitat isolation Gametic isolationarrow_forwardThe condition in which there are barriers to successful interbreeding between individuals of different species in the same community is referred to as * latent variations sterility structural differences reproductive isolationarrow_forwardTwo populations of the same species of frogs have been separated by a mountain range for thousands of years. The females from one population are no longer attracted to the mating calls of the males from the other population. This is an example of which type of reproductive isolation mechanism?

- The reproductive isolating mechanism in which two closely related species live in the same geographic area but reproduce at different times is (a) temporal isolation (b) behavioral isolation (c) mechanical isolation (d) gametic isolation (e) hybrid inviabilityarrow_forwardWhat are factors which causes two hybrid populations to separate? Reinforcement Fusion Stabilityarrow_forwardA ring species is composed by populations arranged in a circle around a barrier with one boundary characterized by reproductive isolation.

- The biological species concept distinguishes two species based on the degree of genetic exchange between their gene pools. True Falsearrow_forwardWhich of these outcomes are examples of reproductive isolation? Select all that apply. Individuals of different species are physically compatible and can engage in sex Hybrid individuals cannot produce offspring Hybrid individuals or their offspring have similar fitness to the original species Reproduction occurs at different times Mating occurs but fertilization does not occurarrow_forwardAssume you are studying a population of ocean shrimp that reproduce asexually. You sequence the ocean shrimp and the species that is their closest living relative that reproduces sexually. You find that the asexually reproducing species has a higher number of mutations in the genome. This finding would provide support for which of the following ideas?
