Changes in groups of organisms over time produce variations in a population. This relates to .?
both Macroevolution and Microevolution Good luck with Novanet. God help you.
How do palnts an animals breeders use genetic variations?
Genetic variations observed in phenotype can be used to produce plants or animals that either have that characteristic, or if it is an undesireable trait the individuals that have it can be culled from the reproductive population.
Changes in genes occur when organisms produce?
changes occure when organisms produce are called fertile offspring.
What is a genetic drift and when does it occur?
Genetic drift is the spread of specific random variations throughout the gene pool in the absence of specific selection pressures. There's always random variation in the population, but there aren't always changes in the environment for the population to adapt to. So natural selection, in stead of moving the population towards adaptation, might select from that random variation to move 'sideways', as it were, to a state that's equally well-adapted to the environment as what came before, but different. As random variation may produce many variants that are, more or less, equally well-adapted to their environment, the direction of evolution that results is more or less random. Because variations may spread throughout small populations faster than throughout large populations, and because a large gene pool has a stabilizing effect on the spread of variations, small populations drift faster than large populations.
What causes changes in allele frequency during genetic drift?

How does a community of pioneer plants produce change that cause its own destruction?
simple the diversity of the plants each plant has DNA just like us mutations (variations) can change for the better or the worse which then will make generations occur.
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.
Which process allows a species to produce new generations of individuals?
reproduction
''what'' changes produce new substances?
chemical changes
Why is sexual reproduction a source of genetic variations?
When alleles are recombined during sexual reproduction, they can produce dramatically different phenotypes. Thus, sexual reproduction is a major source of variation within many population.
Changes in genes occur when organisms produce?
changes occure when organisms produce are called fertile offspring.
What are two parts of sexual reproductions that produce genetic variations?
sperm and egg
