What is a reproductive barrier in which the zygote dies before birth?
postzygotic barrier
Can horses live in the coastal plains in Georgia?
of course they can, there are wild horses on the barrier islands. Cumberland for example, and some of the most successful ranches in Georgia are in the coastal plains.
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
Fringing reef that has grown oceanward?
barrier reef
What is an example of a postzygotic reproductive barrier?
the correct answer is:A. hybrid sterility
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?
Hybid sterility would be a barrier to postzygotic reproduction. This means that the hybid is sterile. Hybid breakdown and inviability are also barriers.
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?
postzygotic
The type of reproductive barrier that occurs when two species mate but fail to produce fertile hybrids is referred to as?
The Postzygotic Barrier prevents animals of different species from producing fertile offspring. This barrier is a mechanism of reproductive isolation.
What is an example of postzygotic isolation?
a) Offspring of two individuals of interbreeding species die early
What is Mechanical Isolation?
There are two types: prezygotic and postzygotic. Prezygotic barriers prevent mating from even happening. If mating does occur, postzygotic barriers reduce the chances that an offspring will survive before being born. One prezygotic reproductive barrier is mechanical isolation.
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.
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
