The original source of genetic variation that serves as the raw material for natural selection is what?
Generally, mutation.
What are two types of mutation?
From another angle: beneficial and detrimental.
A change in the nucleotide base sequence of gene or DNA molecule is called a what?
this is called a mutation
Difference between body cell mutation and sex cell mutation?
A mutation in a sex cell may be passed on to an offspring. A mutation in a somatic (body) cell cannot be passed on to an offspring, but can potentially cause cancer in the person who has the mutation.
How a mutation may not affect an organisms traits?
A mutation does not affect an organism trait for a reason. It is neutral which depends on the environment.
What is spectation?
a person that watches a sport or competion of any sort
Why is it important that exact copies of DNA are produced during replication?
it is important because without same replication you will have a mutation
Why are somatic mutations generally less important than germ mutations?
Because the somatic mutation only produces the color of the iris of the eye. The germ mutation is in charge of the cell which will produce a gamete. It may be passed onto the offspring. So the somatic mutation isn't as important as the germ mutation.
What is the term for any permanent change in a gene of chromosome?
The permanent change in a gene or a chromosome is called Mutation.

Name 2 major types of mutation?

What is a change or error in the structure of a gene or chromosome?
Chromosomal mutation
Mutation is any change in a gene or chromosome?
mutations
Which type of mutation will have the most evolutionary consequence?
A frameshift mutation will have the most serious effects.A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three.Divisible by three is important because the cell reads a gene in groups of three bases.Each group of three bases corresponds to one of 20 different amino acids used to build a protein.If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly.
What concept is important in Darwin's theory if evolution by natural selection?
That a certain animal will have a mutation and if the mutation is more successful then the original then mutation will live if not, then the mutation will die out and also if you split a group of animals up and have say a rat species from Europe and introduce them to a cold climate or an island like Madagascar then they may evolve to better survive in their environment
What is random errors when DNA is copied called?
It's called a mutation.
A mistake made during copying of genetic information is called a?
A mistake made during copying of genetic information is called a
