b. habitat Prezygotic barriers prevent fertilization from taking place. The external barriers such as geographical, physiological, behavioral, and genetic prevent the flow of gene between two sister species and results in the formation of two reproductively isolated. c. an individual lacking one or more sets of chromosomes; plants the other species does not. c. allopatric speciation. d. genetic drift. c. The fitness of the hybrids found there is only about half that of purebred individuals. They do not hybridize because they each have a unique pollinating insect. Tags: Question 9 . c.

Shared habitats C. Low survival in hybrids D. High fertility in hybrids E. All of the above, 2. This includes pre-zygotic barriers such as gametic, mechanical, geographic, behavioral, or temporal forms of barriers which prevent successful mating because no zygote can be formed. Another example of gametic isolation happens when the sperm is unable to survive or will be less mobile in the reproductive tract of a female from a different species. a. behavioral Rotational Kinematics Overview & Equations | What is Rotational Kinematics? Now Atlantic and Pacific populations of this fish are separate species, and even if they were again to come into contact with each other, they could not interbreed. Find the isentropic efficiency. It is difcult for gametes of different species, such as the red and pur-ple urchins shown here, to fuse because proteins on .

Ethological isolation: Reproductive isolation due to difference in courtship or sexual behavioural patterns between members of closely related species e.g. d. the ocean. a. b. all of the various populations can successfully mate in nature. However, since coral reefs often comprise many species that are all using this strategy, gametic isolation helps ensure that only members of the same species can reproduce with each other. d. temporal Reproductive isolation is a collection of mechanisms, behaviors, and physiological processes that prevent the members of two different species that cross or mate from producing offspring, or which ensure that any offspring that may be produced is not fertile.

For example, the sea urchins Strongylocentrotus purpuratus and S. franciscanus can be induced to release their eggs and sperm simultaneously, but most of the fertilizations that result are between eggs and sperm of the same species. Typically, only members within a species can mate. b. a. Allopatric speciation Part of the "script" calls for the male to high-step, a behavior that calls the female's attention to his bright blue feet, Describe mechanical isolation as a prezygotic isolating mechanism, Mating may be attempted, but morphological differences prevent its successful completion, The shells of two species of snails spiral in different directions:Moving inward to the center, one spirals in a counterclockwise direction, the other in a clockwise direction. answer choices. e.
