Decide whether each of the following scenarios would lead to prezygotic or postzygotic reproductive
isolation:
a) Dragonflies from two different populations have genitals that do not match, so they can't mate
successfully [Select ]
b) Two different species of fish have very different courtship displays, but they can mate and produce a
non-fertile offspring [Select]
c) One species of plant flowers in the winter, while another flowers in early spring
[ Select ]
d) The gametes of two tree species can fuse, but a zygote does not form
[ Select ]
e) A mountain range separates two populations of snakes
I Select]
The reproductive isolating mechanism in which two closely related species live in the same geographic area but reproduce at different times is (a) temporal isolation (b) behavioral isolation (c) mechanical isolation (d) gametic isolation (e) hybrid inviability
Males of different species of the fruit fly Drosophilathat live in the same parts of the Hawaiian Islandshave different elaborate courtship rituals. These rituals involvefighting other males and making stylized movements thatattract females. What type of reproductive isolation does thisrepresent?(A) habitat isolation(B) temporal isolation(C) behavioral isolation(D) gametic isolation

- 1) Many organisms have the ability to reproduce asexually as well as perform sexual reproduction. A Scientist, John Smith, was conducting research on aphids that can undergo both methods of reproduction. He determined the males in his population had fertilization rate of 1.8 and a relative fitness of outcrossed offspring was 1.1. a) What is the equilibrium frequency of males in this population? b) Is this population stable equilibrium and why?arrow_forwardThe protruding tusk on a narwhal is an enlarged tooth with sensory capabilities. Narwhals are related to other whales. The extreme phenotype of the tusk demonstrates which type of selection? A)Convergent B)Stabilizing C)Directionalarrow_forwardThe spotting pattern of a guppy is inherited. A spotting pattern that is easy to see in the environment helps a guppy attract a mate. Observe the changes in the image attached below that occurred over 15 generations. The setup happened at 2 aquariums one with fine gravel and no predator present and another with course gravel and no predator present. The guppy populations diverge in their spotting pattern because… A) the guppies that were easily seen successfully found mates and that spotting pattern increased in frequency. B) the guppies that were easily seen were found by predators and that spotting pattern increased in frequency in the following generations. C) the guppies changed their spotting pattern to avoid predators in their environment. D) the guppies changed their spotting pattern to attract mates in their environment.arrow_forward
- If (positive) assortative mating increases in a population, what would expect to happen to genotype frequency over generations? O a) Frequency of the heterozygous genotype will increase. b) Frequency of the homozygous genotypes will decrease. O c) Frequency of the homozygous genotypes will increase. O d) There will be no change in genotype frequency.arrow_forwardIn lizard species "A" the males approach the females directly, bobbing their whole body up and down and displaying their bright blue belly patches as they do so. In lizard species "B", the males slither around the female and bob only their heads. They have no belly patches at all. The females of each species will reject the males of the other species because of these differences. This is an example of isolation. habitat and post-zygotic habitat and pre-zygotic mechanical and post-zygotic behavioral and post-zygotic isolation behavioral and pre-zygotic mechanical and pre-zygoticarrow_forward27) In the fruit fly speciation experiment, individuals from separate populations that were raised using the same food source were more likely to attempt mating with each other than individuals raised on different food sources. Why? A) Because they had adapted to their environment in the same way B) Because this is an example of allopatric speciation C) Because the separate populations were able to carry out some gene flow D)Because the jars were accidently placed next to each other so the males and females were able to recognize each 28) What is needed for natural selection to occur? A) Variation sexual reproduction, competition B) Variation, heritability competition C)Variation, competition, time D) Heritability, competition, sexual reproductionarrow_forward

- Based on the biological species concept, which of the following would lead biologists to conclude that different populations of lizards were actually a single species rather than two different species? A.) lizards from the two different populations mate rarely, and produce hyrbid offspring that are sterile B.) Lizards from the two differnt populations mate during different seasons C.) Lizards from the two different populations mate regularly and produce sterile offspring D.) Lizards from the two different populations matre regularly and produce viable offspring capable of reprodarrow_forwardIn the bighorn sheep population of North America, what would happen if all of the large-bodied, large-horned males were hunted, leaving only small-bodied, small-horned sheep? a)Males could no longer protect females from predators, so eventually all of the sheep would be eaten by predators. b)There would be no phenotypic variation in the population of sheep, and natural selection could not lead to males with larger horns in the future. C)The size of horns would no longer be a heritable traits, and would males would not pass this trait to their offspring. d)Males would begin to use their horns for other behaviors, such as hunting prey or being better competitors.arrow_forwardYou are studying the evolution of resistance to pesticides in pea aphids. Some pea aphids are resistant to the pesticide (solid line) and some are susceptible to the pesticide (dotted line). You compare the fitness of resistant and susceptible aphids in environments with pesticide (exposed) and without pesticide (non-exposed) and produce the graph below: 1.0 non-exposed exposed Environment Fitnessarrow_forward
