What must occur for a gene pool within a population to change?
A genetic mutation within the population.
Which mutation cannot occur in a tRNA encoding gene?
nonsense mutation
What are permanent genetic changes that occur in a body cell called?
rna A mutation.
How mutation can change the gene pool?
If a mutation is present in a gamete, then the mutation will enter the population's gene pool. Once it is in the gene pool, natural selection and genetic drift will influence the frequency that the mutation appears in the population.
If child is born with trisomy when did the mutation occur?
during meiosis
Which of these is one of the conditions for hardy-weinberg equilibrium?
Mutation cannot occur. Apex
What must occur for a gene pool within a population to change?
A genetic mutation within the population.
What conditions are necessary for populations to remain in hardy Weinberg equilibrium?
Mutation cannot occur
Which mutation cannot occur in a tRNA encoding gene?
nonsense mutation
When a child is born chromosomal mutation when did the mutation occur?
During meiosis
When a child is born with a chromosomal mutation when did mutation occur?
during meiosis
How do variation occur in asexually reproducing organisms?
mutation of the DNA is the only way asexually reproducing organisms can obtain variations in their population
What is the one of the conditions for Hardy-Weinberg equilibrium?
All organisms must reproduce.
What are the types of mutations that can occur?
nonsense mutation, missense mutation, frameshift muation, deletion or addition mutation
If an enzyme is absent during polypeptide production a mutation can occur?
This is a true statement. If an enzyme that is involved in DNA replication is not there, then a mutation can occur.
What are mutations that occur at a single point?
Such mutations are called point mutation or gene mutation.
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.
