WEEK-7-Interspecific Hybridization
Interspecific hybridization is the mating between two different species.
• The first reproductive isolating mechanism is geographical,
• The second mechanism is mechanical, basically a lockand-key mechanism,
• The third reproductive isolating mechanism is behavioural,
• The fourth one is temporal,
• The fifth reproductive isolating mechanism is cellular,
• The sixth one is gamete incompatibility,
• The seventh mechanism is F1 hybrid sterility,
• The eighth reproductive isolating mechanism is F2 breakdown.
