What does low genetic diversity do?
Generally, a low rate of evolution.
What are the main mechanisms used by secular scientists to explain evolution?
All educated and not ideologically blinded scientists explain evolution by three primary mechanisms. Genetic drift, gene flow and natural selection.I have the feeling you do not know what secular means.
Is gene mutation within a species know as micro evolution?
Genetic mutation is one of the mechanisms for evolution.Micro-evolution by definition means very small changes in allele frequency (gene mutation).
Stabilizing selection results in more or less genetic diversity?
Stabilizing selection results in less genetic diversity in a population.
What are the mechanisms of evolution?
There are several mechanisms for evolution. The first (and most important) being natural selection, which plays off random mutations. Genetic drift is also another important aspect of evolution. EDIT: It depends on what you mean by "mechanism." Mutations are thought to be the mechanism that causes the change in DNA, then natural selection and Gentic drift take over. Unfortunately, mutations do not hold up and evolution is ultimately left without a mechanism. This article on mutations gives an indepth explanation http://www.answersingenesis.org/articles/wow/are-mutations-the-engine STRAIT FROM THE BIOLOGY BOOK :)
Does sexual reproduction increase or decreases genetic diversity?
increase
The wide variety of life on earth is called?
Genetic diversity
Was Genetic drift a factor in the diversity and evolution of humans?
False, was.
What does low genetic diversity do?
Generally, a low rate of evolution.
Does asexual reproduction provide for genetic diversity the raw material for evolution?
That answer is false it does not provide gentic diversity.
What is stabilizing evolution?
A mechanism (most common) of natural selection where overall genetic diversity decreases due to particular trait or genotype getting 'fixed' into the population. It is usually represented as a parabola on a graph.
What are the two major mechanisms by which bacterial populations generate genetic diversity?
gene exchange and mutation :)
What are the 4 mechanisms by which evolution can occur?
genetic drift, mutation, natural selection, and migration
Why does evolution require diversity within a species?
If everything is exactly the same, there is a lower chance of evolution occurring; diversity is not necessary, but it works quicker. This is because where random mutation is the only thing to introduce wider genetic diversity, it will take a longer time than simply mixing the gene pool up.
What three patterns of biodiversity did Darwin note?
Divergent Evolution, Convergent Evolution, and Coevolution
What is the mechanism of evolution?
The main driving mechanism of evolution is natural selection. Though genetic drigt and gene flow can also cause evolution.
Why don't archegonia and antheridia mature at the same time on a prothallus?
To avoid self-fertilisation which decreases genetic-diversity
