The 5 forms of isolation that can lead to speciation are: temporal, behavioral, geographic, However, on rare occasions (especially in zoos), they have been known to mate and produce hybrid offspring (ligers & tigons!). Question 1 options: mitosis mutation speciation genetic drift sexual reproduction Save Question 2 (5 points) _____________ is the, After a disastrous blizzard, there was a significant increase in the allele frequency of blue eye color in Husky dogs. If this group of fish continued to remain separate from the first population, eventually sympatric speciation might occur as more genetic differences accumulated between them. Paul Andersen explains how reproductive isolation can eventually lead to speciation. The divergence of species is thought to result primarily from the geographic isolation of a population, especially when confronted with environmental conditions that vary from those experienced by the rest of the species, and from the random change in the frequency of certain alleles (known as, Timeless meditations on Earths fragility, and the damage humans do, New Fish Data Reveal How Evolutionary Bursts Create Species, When Evolution Is Infectious - Issue 90: Something Green, Speciation in the Kangaroo Rat, Dipodomys ordii, Systematics of Megachiropteran Bats in the Solomon Islands. 1 0 obj A.productive B.medium C.high.

However, if two rodent populations became divided by the formation of a new lake, continued gene flow would be unlikely; therefore, speciation would be more likely. stream for a quick overview of the content. These variances can lead to evolved differences in the owls, and over time speciation will likely occur unless gene flow between the populations is restored. One form of sympatric speciation can begin with a chromosomal error during meiosis or the formation of a hybrid individual with too many chromosomes.
