Answer:
The options
A. the postzygotic barrier called hybrid inviability
B. the postzygotic barrier called hybrid breakdown
C. the prezygotic barrier called hybrid sterility
D. gametic isolation
The CORRECT ANSWER IS A.
A. the postzygotic barrier called hybrid inviability
Explanation:
Postzygotic barrier is a mechanism that hinders reproduction after fertilization and zygote development. Hybrid inviability occurs when a mating between two organism produces a hybrid that can't strive past the embryonic stages.
In Reduced Hybrid Viability there is a lower tendency to survive for individuals whose parents possesses incompatible genetics, which may have result from sexual union of these parents from varying species.
These two frog species in this case study can be separated through the mechanism of the postzygotic barrier called hybrid inviability.
Two species of organisms from the same genus most of the time are unable to produce offspring and if some are able to, these offspring would not be fertile.
The mechanism for keeping the two frog species separate is the postzygotic barrier called hybrid inviability.
- With regards to hybrid inviability, it means a hybrid's capacity to grow and develop into a healthy, fit adult is reduced.
- This disastrous effect will not allow for gene flow that might occur between two different species as before the hybrid develops, they die..
