Speciation can be explained as a situation when a group within a species separates from other members of its species and develops its own unique characteristics. It can also be described as an evolutionary process by which populations evolve to become distinct species. This means that , through this process a new kind of plant or animal species is created.
The things that were known to be cause of speciation are rivers change course, mountains rise, continents drift and organisms migration.
Behavioral isolation can be described as a barrier that prevents interbreeding between closely related species because there is no mate recognition between females and males of the different species. This means the development of different behaviors that are not recognized or preferred by members in another population.
In this case, behavioral isolation has been the major driver of speciation in flowering plants ,and has been the mechanism that ensure the production of viable offspring.
The probability also depends on the other parents genotype. If the other parent has a genotype of RR then the probability is 0%. If the genotype is Rr it is 25%. And if the genotype is rr it is also 25%.
Germs can be spread many ways, including three types of transmission (or passing of germs):
Direct,
Indirect
Airborne.
Direct transmission means person-to-person contact occurs, and the germs are passed that way. Indirect means that someone spread germs onto an object and when the next person touched that object, the germs spread.
Produce can be called organic if it's certified to have grown on soil that had no prohibited substances applied for three years prior to harvest. ... Prohibited substances include most synthetic fertilizers and pesticides
