Let's say a geographical barrier separates a species into two different population. Which also cause a reproductive isolation ( the two pupolations cannot interbred)

Throughout the time (lets say a million years), the two populations will undergo a lot of changes in their  respective genomes and eventually will form 2 different species.

If there is no reproductive isolation, the 2 population could interbred with one another and there will be no speciation

The results of the punnet square show that one out of 16 offsprings will have both the qualities of having terminal flowers and being a dwarf.

A punnet square can be described as a diagram which depicts the likely outcomes of a cross. In the above punnett square, for the plants to have both terminal flowers and to be dwarf, both the alleles should be recessive for the traits.

Which type of species is the first to occupy a bare site?
Evgen [1.6K]

Answer:

pioneer species

Explanation:

Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support plants.
