- Q1How does the crossing-over of chromosomes that occurs during recombination result in increased genetic variability in a population?The mutation rate decreases during crossing-over.It increases flow of genes from one population to another.It allows for new combinations of alleles to be passed on.30s
- Q2Which of the following statements regarding mutations is true? Mutations –are caused by changes in an organism’s environment.are usually harmful and cause the organisms to die.occur randomly and increase genetic variability.occur at the consistent rate in nearly every population.30s
- Q3Which of the following changes as a result of recombination?Decrease in competition.Increase in genetic variability.Increase in gene flow.Decrease in number of mutations.30s
- Q4In what ways do mutations play a part in the processes involved in the evolution of species?If the mutation is beneficial, it will become more prevalent in the population’s genes over time.Any mutation that occurs may affect the population’s gene pool that is already established.Most mutations that occur will spread quickly throughout a population, creating new species.Some mutations are contagious and lethal, which can lead to the extinction of a population.30s
- Q5Which of the following phenomena usually only has an effect on very small populations?gene flowmutationsrecombinationgenetic drift30s
- Q6Genetic drifta change in the gene pool due to a CHANCE event (fire, flood etc)movement of alleles in or out of a populationnew combinations of alleles and genotypes as a result of sexual reproduction30s
- Q7Gene flowa change in the gene pool due to a CHANCE eventirreversible changes to the alleles in a genemovement of alleles in or out of a population30s
- Q8Mutationirreversible changes to the alleles in a genemovement of alleles in or out of a populationa change in the gene pool due to a CHANCE event30s
