Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

Question

the choices are homogenization and speciation for all three

Identify whether hybridization would likely lead to speciation or homogenization in each scenario.
Several breeding pairs of cactus finch ground finch hybrids have successfully produced fertile, viable offspring for at
least three consecutive generations. These hybrids have been unsuccessful breeding to non-hybrid cactus finches or
ground finches. Are the hybrid finches likely to be speciating or homogenizing?
The Texas bluebonnet, a flower native to Texas, grows wild along roadsides. It is also planted along roadsides in many
beautification projects across Texas. Breeding between the planted bluebonnets and wild bluebonnets produces a hybrid
that is genetically compatible with both parental varieties. Are the hyrbid bluebonnets likely to be speciating
or homogenizing?
Helianthus anomalus is a hybrid sunflower created by the natural breeding of H. annuus and H. petiolarus. Helianthus
anomalus is a fertile, viable hybrid that can only successfully reproduce with other H. anaomalus. Are the hybrid
sunflowers likely to be speciating or homogenizing?

Definition Definition Process by which new species arise. This occurs when populations of a species become isolated and diverge, developing unique traits through natural selection, genetic drift, or other mechanisms. Over time, these differences accumulate until the populations can no longer interbreed and are considered separate species.

Which of the follwing data would support the suggestion of natural interspecific hybridization with weak postzygotic isolation? A. magenta flowered hybrids found in the wild were infertile and bidirectionally crossing with parental species B. magenta flowered hybrids found in the wild were preferentially pollinated by introduced honeybees rather than parental pollinators C. In the laboratory, offspring resulting from crosses between I. cavalcantei, I. marabaensis showed a mixture of parental floral characteristics D. In the laboratory, offspring resulting from crosses between I. cavalcantei, I. marabaensis and magenta flowered hybrid plants were autotropic and showed hybrid viability
Distinct species that are able to interbreed in nature are said to “hybridize,” and their offspring are called “hybrids.” The gray oak and the Gambel oak can mate to produce fertile hybrids in regions where they co-occur. However, the gene ﬂow in nature is sufﬁciently limited that, overall, the two species remain phenotypically distinct. If the hybrid offspring survive well and reproduce to the extent that there is a large population of hybrid individuals that breed between themselves but do not interbreed with either of the two original parent species (the gray and the Gambel), which of the following would you say most likely led to the new hybrid species?(a) prezygotic reproductive barriers (b) sympatric speciation (c) allopatric speciation (d) postzygotic reproductive barriers (e) none of the above
Within a population of sunflowers, a new individual has a novel dominant mutation that causes it to flower 4 months earlier than the rest of the population. That sunflower survives and successfully self-fertilizes, leading over time to a novel population that evolves larger leaves and smaller flowers. This new population does not interbreed with the original population, although they are found in the same areas. This is an example of Allopolyploid speciation O Behavioral isolation O Allopatric speciation O Sympatric speciation O Adaptive radiation
Which of these is an example of a key innovation? A caterpillar of a butterfly species provides honey to an ant colony in order to receive protection and care. A founding population of honeycreepers evolves beaks capable of cracking the seed of a tree species in their new habitat. A new flower color morph arises in a plant population, but an associated pollinator does not distinguish flowers by color. Co-occurring diploid species of wheat and goatgrass hybridize to form a viable tetraploid offspring that can no longer breed with its parents.

Indicate the order in which the following steps would take place to result in Sympatric Speciation [enter 1 for the first step, 2 for the second, etc; write only the number -- no words, no spaces] As they adapt to their specific environments, the fitness of any hybrid formed is reduced. Reproductive isolating mechanisms are selected for so that less fit hybrids are not formed. Two species now exist. Interbreeding populations connected via gene flow occur across a range. The populations in the new environment adapt to their particular circumstances while the remainder stay as they were. Something happens so that some members of the populations/species change their environment (shift hosts; have a genetic change like polyploidy or inversions), so that they are separated from the others even thought hey are living in the same area.
a) How many of the gene trees do you expect to look like the species tree? b) You observe three gene trees in which species X and Z are the closest relatives and seven gene trees where X and Y are the closest relatives.

A genome duplication event, creating a tetraploid plant from a diploid parent plant, can sometimes result in the creation of a new species. This type of speciation is called allopatric adaptive radiation sympatric gradual speciation Which of the following is an example of a postzygotic barrier?

Sympatric speciation by allotetraploidy has been proposed as acommon mechanism for speciation. Let’s suppose you were interestedin the origin of certain grass species in southern California.Experimentally, how would you go about determining if some ofthe grass species are the result of allotetraploidy?
Hybridization was not originally recognized as a mechanism of speciation by either Darwin or the researchers of the "new synthesis". However, today there are many examples of species that have originated through hybridization. What is the best explanation for why we have so many examples of species originating through hybridization? Hybridization is more likely to occur in regions where scientists have put in more effort studying speciation Hybridization has been carried out frequently by farmers attempting to produce new, better species to grow Hybridization occurs fairly regularly, and when it leads to new species only takes a few generations, which is fast enough for researchers to see fairly easily Hybridization is fairly easy to study in captivity
