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.


Why are dominant alleles that cause lethal disorders less common that recessive alleles that cause lethal disorders?

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.


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.

Is the deletion mutation dominant or recessive?

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.


Why are lethal dominant disorders so rare?

Lethal dominant disorders are rare because they typically result in early embryonic lethality or severe health issues that prevent affected individuals from surviving to reproductive age. In these disorders, only one copy of the mutated gene is needed to manifest the condition, but if the mutation is lethal, it often leads to miscarriage or death shortly after birth. Consequently, the genes responsible for these disorders are not passed on to future generations, limiting their prevalence in the population.
