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 the lethal gene in hamsters?

With most lethal genes in hamsters where both germ cells contain the mutant gene death or significant deformity results, but where only one germ cell contains the mutant gene the resultant offspring are healthy. A lethal gene is created when a mutation carries a "double helping" of a particular gene. The result will be the death of the hamster. The only lethal genes currently known that the average pet owner might come into contact with is the Light Grey (or Lethal Grey) and the Dominant Spot. There are other lethal genes out there but they are not in general circulation and most are confined primarily to laboratories. In the event that two hamsters carrying lethal genes are bred, approximately one quarter of the unborn pups will die before the birth. Under normal conditions the mother's body would absorb the dead pups, if not, it is likely that the mother will also die. Any surviving hamsters with these genes do not generally show any adverse affects.


Explain why lethal dominant genes are much rarer than lethal recessive genes?

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.

How would a lethal allele be dominant?

Since we inherit genes and not traits, the dominant allele might contain the genes that increase risk for disease or disorder. Genetic disorders most often occur in early human development.
