the example of lethal dominant mutation is huntington's disease.
Lethal Mutation.
lethal mutation
The mutation may be passed on to an offspring. Depending on the mutation, it may have no effect, or it could be lethal.
Deviation causes death/mutation of cell, bro.
Chromosomal mutations can be either dominant or recessive, depending on the specific mutation and how it affects the expression of genes on the altered chromosome. Some chromosomal mutations can lead to a dominant phenotype if they result in the duplication or gain of genetic material, while others can lead to a recessive phenotype if they result in the loss or deletion of genetic material.
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.
A lethal dominant gene prohibits the organism from reproducing irregardless of the paired gene, so it is removed from the gene pool as soon as it appears. A lethal recessive gene, on the other hand, does not prevent reproduction unless it is paired with another lethal recessive, so it may be passed down through many generations before becoming paired and preventing reproduction.
dominant
The mutation may be passed on to an offspring. Depending on the mutation, it may have no effect, or it could be lethal.
it depends on what mutation you speak of. some are and some are not.
It's an autosomal dominant disease. Source: http://en.wikipedia.org/wiki/Achondroplasia
Asthma doesn't have a gene so its neither
A deletion mutation can be dominant or recessive, depending on the specific gene affected and the consequences of the deletion on the protein encoded by that gene. In general, the impact of a deletion mutation on an individual's phenotype will determine whether it is dominant or recessive.
No, it is a dominant gene
yes
