What else can I help you with?
The type of reproductive barrier that occurs when two species mate but fail to produce fertile hybrids is referred to as?
The type of reproductive barrier you are referring to is called "hybrid inviability" or "hybrid infertility." It occurs when the offspring of two different species are unable to reproduce themselves, often due to genetic incompatibility between the parents.
Which one of the following is an example of a postzygotic reproductive barrier A Hybid sterility B habitat isolation C Gamete isolation?
A Hybrid sterility is an example of a postzygotic reproductive barrier. This occurs when the offspring of two species are sterile and cannot produce viable offspring of their own. It is a mechanism that prevents gene flow between species after mating has occurred.
What is an example of a postzygotic reproductive barrier?
A postzygotic reproductive barrier occurs after fertilization. One example is hybrid inviability, where the offspring of two different species have genetic incompatibilities that prevent them from developing or surviving normally.
What could cause reproductive isolation?
Any factor that in nature prevents interbreeding between individuals of the same species or of closely related species, for example geographic separation is itself a reproductive isolation because is a factor that prevents interbreeding. -extinction of one species -production of infertile offspring -development of physical differences
What is a prezygotic mechanism?
prezygotic or postzygotic
The type of reproductive barrier that occurs when two species mate but produce sterile hybrids is referred to as?
a post-zygotic barrier
What type of reproductive barriers separate a pair of species that could interbreed except that one mates at dusk and the other at dawn?
The type of reproductive barrier in this scenario is called temporal isolation. It prevents interbreeding between species by timing their reproductive activities differently, such as one species mating at dusk and the other at dawn. This difference in mating times reduces the chances of individuals from both species coming into contact to reproduce, thus maintaining their genetic isolation.
How does temporal isolation work in preventing species from interbreeding?
Temporal isolation is a type of reproductive barrier that prevents species from interbreeding by having different mating times or seasons. This means that even if two species are in the same area, they may not be able to reproduce because they are not fertile at the same time. This helps maintain the genetic integrity of each species by keeping them from producing hybrid offspring.
What Factor is necessary in the formation of a new species?
Isolation or reproductive barrier is necessary in the formation of a new species. This can occur through geographical isolation, behavioral differences, or genetic mutations that prevent interbreeding between populations.
What animals can have a baby with a woman?
No animals can have offspring with a woman. Each species has a specific reproductive system that generally prevents interbreeding between different species.
What is it called when a species evolves into and new species without a physical barrier?
This is called sympatric speciation, where a new species forms within the same geographic area as the parent species without a physical barrier separating them. It can occur due to factors such as reproductive isolation, ecological specialization, or genetic mutations leading to divergence.
What is an example of prezygotic barriers?
An example of a prezygotic barrier is temporal isolation, where two species breed at different times of the day or year. For instance, one species of frog may breed in the spring, while another breeds in the fall, preventing them from mating even if they inhabit the same area. This reproductive timing difference ensures that the two species do not interbreed, maintaining their distinct genetic identities.
