They are mistakes in copying, they are negative(never benificial to the organism), are omission of information.... got it from my test :)
NO they are not always negative. They CAN be beneficial. Look it up. It's also in your Science book.
What else can I help you with?
Does inducing mutations produce organisms with beneficial traits?
Inducing mutations can result in organisms with beneficial traits, as some mutations may lead to new desirable characteristics. However, the majority of mutations are neutral or harmful, so the chances of producing a beneficial trait are relatively low. Additionally, the process of inducing mutations can also introduce unwanted genetic changes that may negatively impact the organism.
How are mutations expressed?
Mutations are expressed through changes in DNA sequence, leading to altered protein production, which can result in various phenotypic changes. These changes can be beneficial, harmful, or neutral depending on the specific mutation and its effect on the organism. Mutations are ultimately reflected in an organism's traits and characteristics.
What are the things that mutate and cause characteristics to suddenly change?
Mutations in an organism's DNA can cause sudden changes in characteristics by altering the genetic code. Environmental factors such as radiation or chemicals can induce mutations that lead to changes in traits. Genetic recombination during reproduction can result in new combinations of traits in offspring.
Why are mutations called agents of change?
Mutations are called agents of change because they introduce new genetic variations into an organism's DNA, leading to different traits or characteristics. These changes can result in evolution and adaptation to environmental pressures, making mutations essential for genetic diversity and the survival of species.
What do mutations cause in genotype and phenotype?
Mutations can cause changes in the genotype by altering the DNA sequence. These changes can then affect the phenotype by influencing the expression of certain traits or characteristics in an organism.
What was Mendel's particular interest in agriculture?
Genetics, mutations and inheritable characteristics.
What characteristics does an abnormal genetic test have?
An abnormal chromosome analysis report will include the total number of chromosomes and will identify the abnormality found. Tests for gene mutations will report the mutations found.

Did Darwin believe that mutations are the main cause for evolution?
At the time that Darwin published his work the theory of genetic transfer of characteristics by Gregor Mendel had not been published. As a consequence genetic theory, mutations, recessive characteristics and allof those issues would be unknown.

Why are mutations useful in selective breeding?
Mutations introduce genetic diversity, allowing breeders to select for desirable traits. This diversity can lead to the development of new traits or improvements in existing ones, enhancing the breeding process. By selecting for advantageous mutations, breeders can accelerate the breeding of plants and animals with desired characteristics.
What characteristics of a population would most likely indicate the lowest potential for evolutionary change in that population?
Asexual reproduction and few mutations
New heritable characteristics can result from?
mutations of genes in an organism's sex cells & new combinations of existing genes during sexual reproduction.
What type of mutations improve and organisms chance for survival and reproduction?
Mutations that improve an organism's chance for survival and reproduction are typically beneficial mutations, which enhance traits such as disease resistance, adaptability to environmental changes, or efficiency in resource utilization. These mutations can lead to advantageous physical characteristics, behavioral adaptations, or improved metabolic processes, giving the organism a competitive edge. Natural selection then favors these beneficial mutations, increasing their prevalence in the population over generations. Examples include mutations that confer antibiotic resistance in bacteria or enhanced camouflage in prey species.
