what is isolation?describe the different types of reproductive isolation
Answers
Answer:
These include temporal isolation, ecological isolation, behavioral isolation, and mechanical isolation. Post-zygotic barriers: barriers that come into play after two species have mated. These include genetic incompatibility, zygotic mortality, hybrid inviability, hybrid sterility, and hybrid breakdown.
Reproductive isolation is defined as the inability of members of one population to breed with members of another population because of innate, genetic factors.
The mechanisms of reproductive isolation are a collection of evolutionary mechanisms, behaviors and physiological processes critical for speciation.
Two major types are- pre-zygotic barriers and post-zygotic barriers.
1. Pre-zygotic barriers: Pre-zygotic barriers are obstacles that are present before an egg can be fertilized. Some examples of pre-zygotic barriers include temporal isolation, ecological isolation, behavioral isolation, and mechanical isolation.
2. Post zygotic barriers: post-zygotic barriers mean the animals mated but no offspring occurred after they did so. It can also mean the offspring is a hybrid and is not viable, sterile or both.
