N-normal l-lethal Nl so, dominant normal and recessive lethal, making him/her normal but carries a lethal allele.
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
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 lethal is a genetic trait. If the genome of an individual has the trait, it is expressed and makes it impossible for the individual to have descendants. Its effects cause foetal or embryonic death.
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.
Yes. Once it hits your throat, it can possibly freeze it, due to the extreme temperature of -109 degrees F. dry ice is LETHAL.
Environmental temperature change would effect everything from crop growth to hibernation. It would effect me as a homo sapien greatly as all of my crops would be dying - leaving me to starve - and the temperatures that I have adapted to would no longer be the ones I would be subjected to. This could potentially be lethal. Of course, the effects of environmental temperature change would vary depending on the scale of the change.
A fever, but not lethal.
There is NO "no effect dose" dose or "lethal effect" dose for viruses, bacteria, and other microorganisms, because they make you ill by multiplying at first in number ('growth')

Yes. The effect can be lethal.
It keeps a potentially lethal amperage from going through your body.
Any metallic bullet fired from a gun can be lethal. Pistol ammo is not designed for different degrees of lethality, but is designed for effectiveness in stopping and attacker. That is likely to be a jacketed hollowpoint cartridge.
It is not lethal to take whiskey with nitravet 10 mg. It is a sleep induced agent. So, It increases the effect of alcohol and insomnia behaviour.
Lethal dose means you die from it. hair falls out, gums start to bleed. internal organ failure. extreme cases, damage similar to heat burns.
The mutation may be passed on to an offspring. Depending on the mutation, it may have no effect, or it could be lethal.
Thermoduric bacteria are those that survive the temperatures used in pasteurisation: 63ºC for 30 minutes or the equivalently lethal temperature.
