Underlying the morphological species concept is the assumption that anatomical differences reflect Select one 0 a. different mating behaviors b. signiricant difterences in lifestyle c. substantial genetic difterences O d. the occupation of unique ecological niches. The most significant forces dnving allopatric speciation are the Select one a. different genetic drits affecting each population b. behaviors that prevent the two populations from mating O c. different selective pressures affecting each population. d anatomical differences that prevent the two populations from mating Sympatric spiaton occurs when a subpopulation forms a new species Select one O a. after being separated from its parent population. b. that is identical to its parent population c. located among its parent population. d. that evolves faster than its parent population.Explanation / Answer
1. Underlying the morphological species concept is the assumption that anatomical differences reflect - substantial genetic differences.others can not be true as morphological difference does not really be proved for mating or occupation or lifestyle.As by morphology a fish and a whale can be similar but actualy they are not.A fish is a pisces whereas a whale is a mammal.
2. The most significant forces dividing allopatric speciation are the - different genetic drift affecting each population.By definition allopatric speciation is caused by geographiacal barriers and genetic drift can be a reason for geographical barrier.
3. Sympatric speciation occurs when a subpopulation forms a new species - that evolves faster than its parent population .As by definition sympatric speciation occurs by chromosomal aberration and evolving faster from parent population can be caused by chromosomal aberration.
