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 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 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.
Hybrid inviability is an example of what kind of isolation?
postzygotic
What is an example of postzygotic isolation?
a) Offspring of two individuals of interbreeding species die early
What is a reproductive barrier in which the zygote dies before birth?

What is thought to be essential for the formation of distinct species rather than a continnum form one from of life to another?
Reproductive isolating mechanisms are either prezygotic or postzygotic. These mechanisms ensure that species remain distinct in nature.ChaCha!answer
