Match the type of reproductive isolation with the example that describes it. Some types of isolation do not have a matching exam
andriy [413]

Answer:

1. e. Hybrid performance

2. d. Zygote death

3. a. Gametic isolation

4. f. Ecological isolation

5. g. Behavioral isolation

Explanation:

Hybrid performance is a postzygotic isolation mechanism associated with the ability to produce hybrid offspring, which are adaptively less fit than their progenitors (for example, in this case, hydric stress is a limiting factor for the viability of the hybrids). Zygote death is another postzygotic barrier where the zygote parents' genes fight one another and thus impair the development of the hybrid zygote, causing its death. Gametic isolation is a prezygotic isolation mechanism associated with the incompatibility between female and male gametes (i.e., egg and sperm in animals), which join to form a viable zygote. Ecological isolation, also known as habitat isolation, is a reproductive prezygotic barrier caused by the separation of organisms because they live in different areas or have different ecological/ environmental requirements. Finally, behavioral is another prezygotic barrier where closely related species have different mating rituals. Behavioral isolation is a common practice in many species of invertebrates (such as, for example, arachnids).

GarryVolchara [31]

Answer:

Lamarck thought that organisms came into being through spontaneous generation

He thought they changed from simple organisms to more complex organisms because they had an innate drive to become more complex and perfect

Lamarck thought that when organisms changed their behaviors in response to a changing environment, their bodies changed. When they used a part of their bodies more, it changed accordingly. When they used a part of their bodies less, it shrank
