Choose the best cause and effect sequence for the process of speciation by natural selection. One plant species blooms in June-July, and a second plant species blooms in August-September. One plant species is pollinated by bees and a second plant species is pollinated by moths. Two plant species live on the same mountainside, but one lives on rocky outcrops and the other in open meadows. O Two plant species have inghmpatible gametes.

Choose the answer that best describes Allopatric Speciation. evolution that occurs when populations are separated by behavioral traits. All of these answers are true O evolution that occurs when populations are separated by geographic or physical barriers. O evolution that occurs when populations live in different habitats or exploit different niches.
Consider two species that diverged whilegeographically separated but resumed contactbefore reproduction isolation was complete. Predictwhat would happen over time if two species matedindiscriminately and a. hybrid offspring survived and reproducedmore poorly than offspring from intraspecificmating or b. hybrid offspring survived and reproduced aswell as offspring from intraspecific mating.Provide an example for each to illustrate yourpoint.
Which of the following are good candidates for allopatric speciation? Within a meadow, some butterflies prefer to feed on red flowers while others prefer blue flowers A novel cold ocean current arises and isolates a large portion of mackerel fish individuals A group of male peacock spiders starts displaying a different nuptial dance O A polyploidy event occurring in quaking aspen
To determine: Whether the two hybridized oak tree species in central and eastern North America are "true species" or not.
Describe some models of speciation and give examples of each.
If the two populations in question 2 are determined to still be the same species, did allopatric speciation occur?
Which reproductive barrier is most likely to prevent interbreeding between a polyploid species and its diploid sister species? Behavioral isolation: the two species will not recognize each other as mates O Gametic isolation: sperm and egg with different chromosome numbers cannot complete fertilization Hybrid infertility: differences in chromosome numbers will result in infertile hybrids O Mechanical isolation: differences in reproductive structures will prevent interbreeding O Temporal isolation: the two species will not reproduce at the same time of year
Prezygotic Isolating Mechanisms: Behavioral isolation canprevent individuals of different species from mating. Explorehow sexual selection contributes to behavioral reproductiveisolation. Explain your answer in a well defined manner.
