What is a detrimental gene?
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
Is an organism that is homozygous for many recessive traits at a disadvantage?
An organism that is homozygous for many recessive traits may be at a disadvantage due to the expression of those recessive traits. These traits may negatively impact the organism's overall fitness, making it less well-adapted to its environment compared to organisms that do not have as many recessive traits expressed.
What element has negatively charged protons neutron's and electrons?
None.Protons are always positively charged, electrons are always negatively charged and neutrons are always electrically neutral. And this is true in the case of all elements.
Mutations that occur in body cells will always be life threatening to the organism?
Not necessarily. Mutations in body cells can vary in their impact, ranging from harmless to life-threatening. Whether a mutation is life-threatening often depends on factors such as where the mutation occurs, its effects on important genes, and whether it leads to uncontrolled cell growth or other harmful consequences.
What is the difference between genetic polymorphism and mutation?
A mutation is a genetic change that has occurred in an individual organism. (e.g. an A is changed to a G in a cell of an organism.) A polymorphism is the existence of multiple genetic varieties within a population. (e.g. At a particular place in the genome, some organisms within a population have A's and other organisms within the population have G's.) Note: 1. Mutations and polymorphisms can be advantageous, deleterious, or neutral. 2. All polymorphisms began their existence as mutations. A mutation always occurs in an individual, but can become a polymorphism if it is heritable (i.e. if the mutation affected the germ line) and if it succeeds in spreading through a significant proportion of the population.
What is the result if mutations occur during meiosis?
Mutations during meiosis can lead to genetic variability in offspring. Depending on the type and location of the mutation, it can result in genetic disorders, altered traits, or have no noticeable effect.
How stress affects you?
Stress always affects the person negatively. It causes the person to suicide sometimes. But that person should do anything foolish that to hurt himself.
What stress causes to the mind and body?
Strain
What is a detrimental gene?
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
Is a mutation always negative?
Mutations do not necessarily have to affect organisms negatively. It is occasionally through the mutation of genes that species are able to evolve and become better adapted to their climate. For example, it has been theorised that one of the mutations of the jaw muscle lead partially to the evolution of humans. Such a mutation had both negative and positive effects: it decreased jaw strength, but allowed the headcase to expand, allowing for the brain to increase in size. So while it could be taken as a negative influence, there have been much greater positive affects to the organism.
Stress has a positive impact on both attitudes and performance?
No stress does not have any positive effect. It always affects the person negatively. It causes the person to behave foul manner.
A mutation in a gene may not affect an individual's phenotype because?
the mutation may occur in a non-coding region of the gene, resulting in no change to the protein produced. Additionally, the mutation may be silent, meaning it does not alter the amino acid sequence of the protein. In some cases, the organism may have redundant genes that compensate for the mutation, allowing it to function normally.
What type of mutation is a beneficial to an organism?
Those that increase your health, your survival, your ability to have children and of course too many other benefits to name, here. Generally mutations are the key to natural selection. Beneficial mutations that occur allow an organism to survive longer, thus reproduce more, passing this mutated trait down to their offspring.
Describe the differences between the original and mutated sequences?
An original sequence is a sequence of DNA that has no mutations or damage. A mutated sequence is one that has had some type of damage or change occurs to the DNA. A mutation is not always a bad thing, and may have very little impact on the organism that has the mutation.
Is 'mutations are beneficial to organisms' a true statement about mutations?
Not always. Mutations can have either beneficial, neutral, or harmful effects on organisms. Whether a mutation is beneficial or not depends on how it impacts the organism's ability to survive and reproduce in its environment.
Is A somatic mutation is always transmitted to the offspring?
no
Does a DNA mutation always result in a change to the protein?
No, a DNA mutation does not always result in a change to the protein. Some mutations are silent and do not affect the protein's function.
