In the biological species concept, it is specified that two organisms are of the same species if they breed and
Select one:
a. produce fertile offspring under normal circumstances.
b. are unsuccessful in producing offspring.
c. produce fertile offspring under laboratory conditions only.
d. produce any offspring.
Answer:-Option (a) is correct.
According to the biological species concept it is specified that, two organisms belong to the same species if they can interbreed to produce viable, fertile offsprings.
For instance- If two dogs that live in different places ,if they meet or breed they can produce healthy fertile puppies.
Even though in some cases organisms of different species can made and produce healthy offspring, but the offsprings are infertile can't produce.For example when a female horse and male donkey mate, they produce hybrid mule who is infertile.

According to the ecological species concept, in some cases different species: Group of answer choices A.can never produce offspring B.can breed and produce offspring under unnatural circumstances C. can only produce offspring in they live in the same ecosystem
Consider a group of bacteria that you are trying to classify as either the same species or different species. They are morphologically identical, reproduce by binary fission but live in slightly different environments. Which species concept(s) could be applied to these organisms? Select All that Apply. A) Binomial B) Morphological C) Phylogenetic D) Ecological E) Biological I have my assumptions but I wanted to some input on this. Please explain your reasoning for all selections and for those that you...
The biological species concept (BSC) defines species based on reproductive isolation; distinct species fail to produce fertile hybrids. If the BSC is the “gold standard” for understanding what species are, why are most species still recognized based on phenotypic differences (i.e. the morphological species concept)? a. The mating experiments necessary to confirm reproductive isolation are too time-consuming to carry out on all but a small fraction of presumed species pairs. b. Reproductive isolation is not a meaningful concept in the...
Two species interbreed occasionally and produce vigorous, fertile hybrids. When the hybrids breed with each other or with either parent species, however, the offspring are feeble or sterile. These species are affected by a) gametic isolation. b) reduced hybrid fertility. c) reduced hybrid viability. d) hybrid breakdown.
Under the biological species concept, which of the following statements is/are true? a) Gene flow can occur between species. b) Species are independent evolutionary lineages. c) Isolating mechanisms prevent gene flow between species. d) Geographic isolation and differences in the timing of mating are two mechanisms that allow populations to genetically diverge. e) Donkeys and horses are not species.
Which of the following statements about species, as defined by the biological species concept, is (are) correct? I. Biological species are defined by reproductive isolation. II. Biological species are the model used for grouping extinct forms of life. III. All members of a species can potentially interbreed. A) I and II B) I and III C) II and III D) I, II, and III
The biological species concept defines a species as a group of populations whose members have the potential to interbreed in nature and produce viable, fertile offspring. This means that all members of these populations can contribute to a common gene pool. These populations belong to the same species. Genes are transferred between these populations through both direct and indirect gene flow. Biologists used genetic techniques to look for gene flow in 12 wild populations of mice. The populations (designated A...
Which of the following scenarios would result in a different species designation for two populations under the phyiogenetic and biological species concepts Select one O a, there is no gene flow, all hybrids are sterile O b each population forms a monophyletic group; populations mate during different seasons O c. there is no gene flow, fertile hybrids are produced when bred in the lab O d each population is paraphyletic, fertile hybrids are produced when bred in the lab
A species is a. Local population that does not breed with other similar populations, although they could. b. An individual that has characteristics different from all other organisms. c. A group of organisms in which individuals can produce offspring that also reproduce. d. All of the choices.
Any group of the same biological species in a geographical area that can mate and produce offspring. A. Gene Pool b. Natural Selection c. Migration d. Cline e. Gene Flow f. Nonrandom Mating g. Genetic Load h. Population i. Genetic Drift Occurs when people with a particular genotype are more likely to produce offspring under a specific environmental condition. A. Gene Pool b. Natural Selection c. Migration d. Cline e. Gene Flow f. Nonrandom Mating g. Genetic Load h. Population...
