A lethal recessive trait is a genetic condition caused by a recessive allele that, when two copies are inherited (one from each parent), leads to the death of the organism before or shortly after birth. These traits prevent affected individuals from surviving to reproductive age, resulting in the elimination of the harmful allele from the population over time.
In mice the YY genotype is lethal during embryonic development. This means that the mating of heterozygous individuals will produce a ratio of 2:1 Yy to yy offspring.A 'YY' genotype is homozygous dominant for that particular trait. If it is Yy, it will be heterozygous.
The dominant trait masks the recessive trait.
A weak trait that is masked by a stronger trait is often referred to as a "shadow trait" or a "secondary trait". These traits may not be immediately apparent due to the dominance of the stronger trait.
It is harmful to inhale. and can be lethal if it ignites or explodes.
recessive trait
Trait, expressed in the phenotype if present in the genotype, that precludes having descendants.
it is probably homozygous for the resseive allel
If both parents carry the trait then there is a only a 25 percent chance the pregnancy will abort but there is a 75 percent chance the child will carry the trait and that can cause abnormalities during the pregnancy and afterwards.
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.
In mice the YY genotype is lethal during embryonic development. This means that the mating of heterozygous individuals will produce a ratio of 2:1 Yy to yy offspring.A 'YY' genotype is homozygous dominant for that particular trait. If it is Yy, it will be heterozygous.
The trait that is hidden is recessive trait.
A lethal allele is maintained in population for example when you use bug spray on cockroaches there will be at least one cockroach with an allele that protects it from the bug spray, it then breeds and the allele Is passed to it's offspring and they will also be immune to the pesticide. Those babies will most likely breed with each other when they are mature passing on the allele from both of the parents making the offspring 100% immune. It's the same concept for lethal alleles.
the difference between nonlethal and lethal is that they both have lethal in there but non means no so nonlethal means no lethal at all. judy wardell=]

Any alcohol is lethal in large amounts.
His cooking was lethal, it had tentacles and everything!
