- Describe and distinguish between the several types of reproductive isolating mechanisms.
Step by step
Solved in 3 steps
- Propose several mechanisms by which animalsmay synchronize the production of offspring with favorableenvironmental conditions.Name four reproductive barriers and indicate whethereach is pre- or post-zygotic.Explain the significance of reproductive isolating mechanisms and distinguish among the various prezygotic and postzygotic barriers.
- Describe an example of each of the following: a pre-zygotic barrier to reproduction a post-zygotic barrier to reproductionWhat are the relative advantages and disadvantages ofsemelparity and iteroparity? In answering, consider iteroparousspecies that have both short and long expected life spans in theirnatural environments.Define the three types of embryo development and birth and give an example of a species for each: 1) Oviparous 2) Ovoviviparous 3) Viviparous
- 2)Why are organisms that broadcast spawn useful for studying fertilization & development? a)Fertilization does not require multiple gametes b)Fertilization occurs outside the bodies of the parents, so it can be directly observed c)Fertilization is observable because the eggs are large enough to see d)Fertilization occurs without the need for parentsWhy would paired external fertilization be preferable to group spawning?What are advantages of asexual reproduction? Select all that apply. A) In a stable environment, a population that develops from asexual reproduction can grow quickly and thrive. B) In an unstable environment, a population that develops from asexual reproduction can grow quickly and thrive. C) Species that reproduce through asexual reproduction have more genetic diversity. D) Organisms in isolated areas can still reproduce through asexual reproduction.
