Local geographic features.
Describe the steps of speciation beginning with geographic isolation?
Two populations are isolated geographically (or mechanically - perhaps there is a mutation that prevents physical copulation, like a change in the direction of the turn of snail shells). One undergoes some selective pressure that the other does not, such as a change in the environment or new predators moving in. The population under stress adapts to the changes, and the genetic mutations involved are extensive enough such that if the two populations do meet again, they can no longer produce viable offspring.
The type of reproductive barrier that occurs when two species mate but produce sterile hybrids is referred to as?
a post-zygotic barrier
What is Hollandia Produce's population?
The population of Hollandia Produce is 70.
What is KM Produce's population?
KM Produce's population is 33.
Do the plants produce anything in the great barrier reef?
probably - depends on what the wage is
What is the population of Fresh Del Monte Produce?
The population of Fresh Del Monte Produce is 44,000.
The type of reproductive barrier that occurs when two species mate but fail to produce fertile hybrids is referred to as?
The Postzygotic Barrier prevents animals of different species from producing fertile offspring. This barrier is a mechanism of reproductive isolation.
What is productivity in ecosystem?
it is defined as the biomass produce in one growing seasion in a particular geographic area.
How is sympatric speciation similar to allopatric speciations?
allopatric speciation happens when a physical barrier divides two populations of the same species and sympatric speciation happen when no physical barrier divides the member of a population, but methods such as polyploidy (chromosome doubling) do not let the members of the species have fertile offspring, 2 species are formed (the parental "normal" species and the divergent species "polyploids"). Remember that a species is defined as a population that when mated with one another produce fertile offspring. A polyploid and a parental organisms can not produce fertile offspring together so they become two different species and speciation is said to have occurred.
