Mutations are added to a gene pool when a mutation (completely random) occurs in a person. They will pass this gene on to their offspring (and so on, and so forth).

What does not add new alleles to a population gene pool?
1.Which does not add new alleles to a population gene pool?
If a couple with normal phenotypes get married and have a child then what is the chance that the child will develope achondroplasia?
People with achondroplasia can be born to parents who don't have the condition. This is the result of a new mutations. New gene mutations leading to achondroplasia are associated with the paternal age effect (over 35 years old). Studies have demonstrated that new gene mutations for achondroplasia are exclusively inherited from the father and occur during spermatogenesis.
What process produces new alleles of a gene?
There isn't ONLY one way, except for genetic manipulation (from an injected virus which is NOT for immunization); the only other way is via reproduction.
What are 3 causes of variation within a population?
Changes within a gene pool occurring from generation to generation is called microevolution. Allele frequencies in a population may change due to gene flow, genetic drift, natural selection and mutation. These are referred to as the four fundamental forces of evolution. Only mutation can create new genetic variation...the other three forces simply rearrange this variation within and among populations.
Mutations are important for evolution because they .?
Mutations are very important for evolution today because they usually lead to the genetic changes in a given gene pool. They also allow the species to change with the environment.
What can lead to the development of new mutations in the gene pool?
do it own your own ;p
What change in genes or chromosomes that causes a new trait to be inherited?
Mutations create variation in the gene pool by causing new traits to appear
Are mutations the only way to add new genes to a gene pool?
yes. independent assortment and crossing over in mitosis will add new combinations of alleles to the DNA but only mutations will create new genes.
How do new traits arise to create genetic variability?
Random mutations of DNA happen and these get inserted into the gene pool as the species breed.

What type of mutation result when bases are added to gene?
Frame shift mutation occurs when a new codon in inserted. Point mutations occurs when one base, sometimes two, are inserted.

What effect does platae tectonics have on evolution of new species?
If a land mass separates and moves many miles away from it's parent land mass you will possibly split apart a species that lived in the vicinity. Geographic isolation ensues and any mutations that happen in the two populations now statistically vary and can not enter a common gene pool, but enter each separate gene pool. This can cause allele frequencies to change in the separate gene pools, among other processes, to begin new species.
What is cause for mutations of genes can be cause by?
A gene mutation can be caused by radiation. A gene mutation can also be inherited from family members, such as grandparents and parents.
