What else can I help you with?
What is a reproductive barrier in which the zygote dies before birth?
postzygotic barrier
What is less metabolically costly to an animal prezygotic or post zygotic isolation?
Prezygotic isolation because it is usually only a result of different mating calls or times. In postzygotic isolation the organism usually dies before it has a chance to reproduce or is infertile.
The type of reproductive barrier that occurs when two species mate but produce sterile hybrids is referred to as?
a post-zygotic barrier
What is a contraceptive that physically blocks sperm from reaching the egg?
A contraceptive method that physically blocks sperm from reaching the egg is a barrier method, such as a condom or diaphragm. These devices create a barrier that prevents sperm from entering the uterus and reaching the egg, therefore preventing fertilization.
Is ecological isolation a prezygotic isolating mechanism?
Sure is. How can one mate if an ecological barrier is erected between two biological species? Even something as simple as the time of day can be a barrier to mating.
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 is a reproductive barrier in which the zygote dies before birth?
postzygotic barrier
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.
The most important factor in preserving horses and donkeys as distinct biological species?
a postzygotic barrier
Hybrid inviability is an example of what kind of isolation?
Hybrid inviability is an example of postzygotic isolation, which occurs after mating between two different species has taken place resulting in hybrid offspring that do not survive or reproduce.
A mule is prezygotic or postzygotic?
The mule would be considered postzygotic. This is because of the usually sterile reproductive traits that are commonly associated with being a hybrid.
What is an example of postzygotic isolation?
An example of postzygotic isolation is hybrid inviability, where hybrid offspring fail to develop or survive to reproductive age due to genetic incompatibilities between the parent species. This can lead to reduced fitness and ultimately prevent further gene flow between the two species.
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.
A reproductive barrier that prevents species from mating is an example of?
a prezygotic barrier
Why prezygotic isolating mechanisms have an advantage over postzygotic isolating mechanisms?
prezygotic isolating mechanisms were here first and have the advantage over postzygotic because they have had a longer time to develope and get harmful genes out of their population.
How many types of barriers of communication are there?
There are many types of barriers of communication for example; language barrier, physical barrier, emotional barrier, listening barrier, cultural barrier, gender barrier etc
What an example of a chemical barrier?
haha
