Which major change can occur in a small population that is the result of genetic drift?
One problem is that the population will loose it genetic variation. With little genetic variation a population is less likely to have some individuals that will be able to adapt to a changing environment.
One method of protecting the genetic identity of a population is the inability of spermatozoa to fertilize ova of a different species This is called?
Gametic incompatibility is a method of protecting the genetic identity of a population. In this method, sperm transfer occurs but the egg is not fertilized.
Where does reduction occur in an electrolytic cell?
The electrode where reduction occurs
What term is defined as the change in allele frequencies that occurs when a new population is established?
Founder Effect
Reproduction that occurs with an exchange of genetic material is?
sexual
What process occurs when local units of a population become reproductively isolated from other units?
genetic divergence
What are the mechanisms of natural selection?
Basically, natural selection, genetic drift and gene flow into and out of population of organisms.

The situation in which allele frequencies of a population remain constant is called?
That situation is called a Hardy-Weinberg equilibrium. Not actually seen outside of the lab.

What occurs when oxygen is taken from a substance?
reduction
Genetic variation occurs when chromosomes are shuffled in and fertilization?

What is a change in the genetic composition of a population of organism over a period of time?
A change in the genetic composition of a population of organisms over time is known as evolution. This occurs through processes such as natural selection, genetic drift, and gene flow, leading to changes in allele frequencies in a population's gene pool. These changes can result in the emergence of new traits, species, and adaptations.
Reduction of oxygen which forms water occurs during?
The reduction of oxygen that forms water occurs during respiration. It occurs when oxygen and hydrogen mix to form what is called metabolic water.
What is a part of microevolution?
One example of microevolution is genetic variation within a population. This occurs because of the accumulation of small changes in the frequency of alleles (alternative forms of a gene) over generations.
