No. Point mutations, or those resulting from a change in one or a few nucleotides at a single location in a DNA sequence. There are two types of point mutations: base substitutions and frameshift mutations. Not all mutations are in these coding sequences but if they are, then the result can be different or non-functioning proteins. They are considered to be neutral, beneficial or harmful. Two harmful point mutations are sickle cell anemia and polycystic kidney disease.
it can be.......well atleast it was for a Chinese hamster who was temperature sensitive due to the point mutation
the example of lethal dominant mutation is huntington's disease.
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.
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.

A mutation
This would be a point mutation, which may be harmless, or could be lethal, depending on the protein in which it occurred.
Point Mutation- a type of gene mutation in which only a single nucleotide in a gene has been changed.
No
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.
point mutation
point! good luck
