When lethal genes are present in the organism's chromosomes, the organism is unable to survive. Semi Lethal genes are harmful to the organism but does not cause Death. E.g Huntington Chorea in human

What is an example of a lethal mutation?

Albinism, where the animal (or person) has no melanin (color) in their skin or hair, so they sunburn easily and are prone to skin cancer. The irises of their eyes are pink, so their eyes are sun-sensitive. Animals with no coloring of their skin can not hide from predators, so they don't live long in the wild. I don't think albinism is technically a lethal mutation. I think an example of lethal mutation is the overo gene in horses. Two copies of it produce a foal that dies shortly after birth due to problems with its digestive system. Any mutation that causes termination of pregnancy is a lethal mutation.


How mutation affect survival skills of an organism?

It depends on the mutation. Some mutations have no effect on survival, some mutations are lethal, and some mutations make an individual better adapted to its environment, so it will be more fit than those without the mutation, and therefore produce more offspring with the same mutation, which could change the allele frequency of a population.


How can a lethal gene be passed from one generation to the other?

If the lethal gene is recessive, and the parent carrying it is heterozygous for that gene, it can be passed down to offspring in the recessive form. If the mate of the parent happens to be carrying the same gene heterozygously, 50% of offspring will be expected to inherit the recessive lethal gene heterozygously. 25% of the offspring will be expected to inherit the lethal gene homozygously, leading to death. The remaining 25% of offspring we will expect to homozygously inherit the non-lethal gene. 1:2:1 ratio


Why do you think certain mutations persist if they can be lethal?

Certain mutations may persist even if they can be lethal because they may also provide some advantage or benefit to the organism. This advantage could help the organism survive and reproduce, allowing the mutation to be passed on to future generations despite the potential negative consequences. Additionally, some mutations may only be lethal in certain circumstances or at certain stages of development, allowing them to persist in a population.

What is an example of a lethal dominant mutation?

Huntington's disease is an example of a lethal dominant mutation. It is a neurodegenerative disorder caused by a dominant mutation in the HTT gene, leading to progressive loss of motor and cognitive functions, eventually resulting in death.

What is the result of mutation during of meiosis?

The mutation may be passed on to an offspring. Depending on the mutation, it may have no effect, or it could be lethal.

A mutation that results in the death of the individual is called?

A lethal mutation. It can cause severe defects or disruption in essential biological processes that are necessary for survival, leading to the death of the individual.


What impact could a point mutation do?

A point mutation could have no impact or it could be lethal. It depends on whether the mutation changes the amino acid sequence of a protein, or if it changes the amino acid at a critical location in the protein.


Does exposure to cat scans cause lethal cell mutation?

It's possible because they are x-rays.

What is an advantage of sexual repoduction?

Sexual reproduction creates variaty that asexual reproduction cannot provide. If we were all asexual, that means that there are very little variaty(the little part is caused by mutation) and that we would all look alike and be alike. The problem with this is that if a disease spreads in the population that is lethal to one person, then it will be lethal to everyone in that population(unless there was a mutation). Our being able to reproduce sexually has made it easy to not die by a disease that might be lethal to one person.


How mutations can affect organisms?

It depends on if it is in the germ line or in a somatic Cell. In the germ line a mutation can cause birth defects or lethal mutations. In somatic Cells it can cause cancer. The Genetic Mutation will have either of these effects: either beneficial or detrimental.
