Species that occur in the same location and are phenotypically different are called species

Under the phylogenetic species concept Blank______.Multiple choice question.differences among geographically isolated populations cannot be used to distinguish speciespopulations with slight differences could be recognized as distinct speciespopulations that are similar cannot be differentiated as separate species

According to the biological species concept, individuals belong to the same species if they can interbreed in nature and produce viable, fertile offspring. Prezygotic and postzygotic barriers ensure that members of different species do not reproduce with one another. Match the following examples to the specific barriers at work.Two fish species spawn at different depths. Offspring of two newts are sterile. Lion-tigers don't reach maturity. Birds are active at different times of day. Flowers accommodate different insect pollinators Beetle mating display shows different spot patterns.

Which of the following is the best definition of a species?A group of organisms with identical genotypes and phenotypesA group of organisms with a range of genetic mutationsA group of organisms with a range of different characteristicsA group of organisms with similar characteristics that can interbreed to produce fertile offspring2Why are identical twins useful for studying variation? They have identical genotypesThey are brought up in the same environmentThey have identical phenotypesThey have the same parents3Which of the following are examples of genetic variation? Natural eye colourScarsWeightRegional accent4What are mutations?Random continuous changes in the DNAAlleles that cause a genetic conditionPhysical characteristics caused by a genetic conditionVery rare changes in the DNA5Which of the following statements about mutations is not true?They can be caused by a mistake made during mitosisThey can be caused by UV radiation from the sunThey can lead to cancerThey are always detrimental

According to the phylogenetic species concept, a species is a population that Blank______.Multiple choice question.is reproductively isolated from other populationshas evolved independently of other groups of populationshas substantial morphological differences from other populations
