A mutation occurs randomly and can cause a new phenotype. For example, blue eye color is caused by a random mutation in the genes governing eye color. This mutation occurred between 6000 and 10000 years ago. Before that, nobody had blue eyes.

What is the one of the conditions for Hardy-Weinberg equilibrium?
All organisms must reproduce.
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 is the result if mutations occur during meiosis?
The offspring of the organism will have a mutation.
Mutations that occur at one single nitrogen base are referred to as?
Mutations that occur at one single nitrogen base are referred to as a point mutation.
For a mutation to affect evolution it must occur in?
For a mutation to affect evolution it must occur in the dominant allele. This allele is what is passed on.
How does mutation occur in the population?
Mutation can create new alleles, therfore can change allele frequencies in a population.
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.
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
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.
Discuss the causes of variation Living organisms?
Causes of variation is random mutation. Random mutations constantly occur in the genomes of organisms; these mutations create genetic variation. If all living things were same, we will all use up one type of food as our nutrient source and eventually we will run out of food to consume.. making less likely for us to survive..
What are mutations that occur at a single point?
Such mutations are called point mutation or gene mutation.
Breeder induce mutations in organisms to?
Increasing a population's mutation rate would increase the chances of individuals within the population having desirable traits, which can then be selected for using breeding techniques.
Which of these is one of the conditions for hardy-weinberg equilibrium?
Mutation cannot occur. Apex
