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).
What is trans heterozygous?
Trans heterozygous is a diploid organism that is heterozygous but it has two different loci(genes). They each have one natural allele and allele that is different from the natural allele due to a mutation.
What factor would cause a mutation that would cause an allele frequency to increase?
One factor would be isolation and then interbreeding or incest.
How would you describe what an allele is?
*An allele is basically the different forms a particular gene can take (describes the various genotypes/phenotypes a gene can take).* For example there is an allele of a gene which codes for haemoglobin in red blood cells, which gives them their characteristic concave shape. But there can also be a mutation in that gene, which causes a different allele to be produced which gives it a sickle-cell shape, which leads to sickle-cell anaemia.
What is an example of allele frequency?
The frequency for the mutant cystic fibrosis allele among Caucasians is 0.025, while the frequency of the normal allele is 0.975.
What factor determines whether the frequency of the new allele will increase?
Which factor might determine whether the frequency of the new allele will increase in a population where a mutation occurs?
What are three mechanisms that cause allele frequency differences in a population?
Mutation, migration, and genetic drift
When does a mutation have the mutation impact on allele frequency?
When the population is small or When there is no gene flow Small population, germ line mutation, beneficial mutation that gets into many progeny and a good deal of luck.
Which best describes genetic drift?
random changes in allele frequency - apex

When does mutation have a most impact on Allele frequency?
When the population is small or When there is no gene flow Small population, germ line mutation, beneficial mutation that gets into many progeny and a good deal of luck.
Under is condition would a mutation have most impact on allele frequency?
There is no gene flow.
What is trans heterozygous?
Trans heterozygous is a diploid organism that is heterozygous but it has two different loci(genes). They each have one natural allele and allele that is different from the natural allele due to a mutation.
Is homologous recombination a type of mutation?
No. A mutation can change an allele into any other allele. Homologous recombination can only change an allele to the allele of the homologous chromosome.
What describes an allele whose characteristic phenotype is masked by the presence of a different allele?
recessive
What factor would cause a mutation that would cause an allele frequency to increase?
One factor would be isolation and then interbreeding or incest.
Which allele is associated with the BRCA2 mutation?
Allele 3
