SMAC LAD NANVIS SALAD SANDH A hybrid is a combination of 2book Organisms , to determine if they are oful on is if they create more of that hybrid on is healthy 3 2. Compare & Contrast Allopatric & Sympatric Speciation . Allopatric speciation is when that inital population gets divided somehow ( physical barriers prevents mating over time the seperated organisms become new or different species due to differences in onviorment & gene pool) . Sympatric Speciation is when one you have random genetic abnormalities with some members of the population not being able to mate with others in the population and overtime they will most likely become different species 4. Explain the difference between the gradual and punctuated models to of speciation . Species that arise from gradual models accumulate tiny changes (mutations ) over time . Species that arise from punctuated Models are usually products of mutations that have a huge impact on the Morphology (physical changes
