<em>They will have a large number of genetic variations.</em>

Explanation:

Genetic variations arise due to sexual reproduction or due to the process of meiosis.  

Cross-pollination can be described as a process in which the pollen of one flower is transferred to another flower. The pollen when fertilizes the egg in the stigma, will produce offspring with varied genetic characteristics. This will be because the pollen would carry the trait of another flower and the egg of another flower. This will lead to many genetic variations.

The rock formations of eastern North the USA, Western Europe, and northwestern Africa were later found to have a not unusual starting place, and they overlapped in time with the presence of Gondwanaland. together, those discoveries supported the life of Pangea.

Wegener showed that positive styles of rocks on the continents would match with others in some other continents. What did Wegener realize approximately the oldest rocks on the African and South American continents? That they had been connected collectively whilst the continents were arranged to shape Pangaea.J
