Question

Mules, the offspring of a horse and a donkey, fail to produce offspring when mating with horses O The sperm of one species of sea urchin are unable to fertilize the eggs of a similar species o Large dogs and wolves can successfully breed and produce healthy offspring for multiple generations Question 6 The Gradualism model of speciation is best supported by a fossil record with O long periods where the fossils show little change separated by short periods where there is a lot of change O numerous gaps between morphological forms numerous different morphological forms in each period O intermediate forms expressing the accumulation of small changes over time Question 7 In the process of allopatric speciation, what must occur prior to reproductive isolation? geographic isolation O interbreeding

Answer 1

Answer- (d) intermediate forms expressing the accumulation of small changes over time

Gradualism is a model of evolution which theorizes that most occurs from existing species in a slow, uniform and gradual manner. Unlike punctuated equilibrium which states that species remain static until changes occur in spurts of time periodically.
