One of the best pieces of evidence for the process of gene duplication followed by mutations is the occurrence of?
TRANSPOSONS
How does mutation occur in the population?
Mutation can create new alleles, therfore can change allele frequencies in a population.
What is a detrimental gene?
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
What is the original source of all the different alleles of a genes?
A mutation in a pre-existing gene. If the mutation effects the phenotype derived from the gene, it is determined to be a different allele. Mutations can be small (such as a single nucleotide polymorphism) or large (such as entire genome duplication).
Does radioactive decay only cause deletion mutations in the DNA?
No. Radiation can cause rearrangements or alterations in the DNA. Additionally, radiation can cause improper gene replication, resulting in minor duplication and other errors.
What is gene duplication?
Gene duplication is a key mechanism in evolution.
What is the relationship between divergence and amplification?
Gene duplication (or chromosomal duplication or gene amplification) is any duplication of a region of DNA that contains a gene; it may occur as an error in homologous recombination, a retrotransposition event, or duplication of an entire chromosome.
Why is gene duplication seen as potentially event in evolution of species?
Yes. When a gene is duplicated you have one gene doing the job it was doing before and the possibility of the duplicated gene having a beneficial mutation and picking up a brand new job to do and making a newly beneficial protein. Of course if the mutation is deleterious that organism will not pass those genes on any further than progeny. Remember, only germline mutation are passed on to future generations.
Which do you think is generally most harmful a duplication deletion translocation or inversion?
deletion
One of the best pieces of evidence for the process of gene duplication followed by mutations is the occurrence of?
TRANSPOSONS
A chromosome's gene sequence that was abcdefg before modification and abcdlmnop afterward is an example of?
translocation
How can crossing over result in gene duplication?
No, only switches traits inside the crossed over segments
What has the author Melvin L DePamphilis written?
Melvin L. DePamphilis has written: 'Genome duplication' -- subject(s): DNA replication, Genome, Gene Duplication 'Concepts in eukaryotic DNA replication' -- subject(s): DNA replication
How does mutation occur in the population?
Mutation can create new alleles, therfore can change allele frequencies in a population.
Which is a process that eliments harmful alleles from a gene pool?
natural selection
How do gene mutations happen?
mutation are caused by radiation and are 99.9% harmful
What is a process that eliminated harmful allele from a gene pool?
negative selection.
