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.

What becomes of a YY genotype?
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.
What trait masksthe othor form of a trait?
The dominant trait masks the recessive trait.
What is the name of a weak trait that is masked by a stronger 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.
Is natural gas very harmful or lethal?
It is harmful to inhale. and can be lethal if it ignites or explodes.
Why do recessive trail are more common in some cases?
They're not necessarily, but they can be. When a recessive trait is more common, it likely because it was advantageous to have that trait so the species evolved to have more of it in the gene pool. Also, since dominant traits are expressed over recessive traits, natural selection has more of an effect on them.
What is a lethal trait at the cell level of biology?
Trait, expressed in the phenotype if present in the genotype, that precludes having descendants.
What statement can you make about your cats genotype for eye color?
it is probably homozygous for the resseive allel
What is the probability that a pregnancy will abort if the mother and father both carry a lethal recessive allele?
If both parents carry a lethal recessive allele, the probability of their child inheriting two copies of the lethal allele (which would result in the pregnancy aborting) is 25%, as there are four possible combinations of alleles from the parents (25% chance of both carrying the lethal allele, 50% chance of being a carrier, and 25% chance of not having the lethal allele at all).
What is dominant lethal allele?
A dominant lethal allele is a mutation that results in the death of an organism that inherits it, regardless of the other alleles it carries. This allele will prevent the development or survival of the individual, even if it is paired with a normal allele. Dominant lethal alleles are rare in nature due to their negative impact on survival and reproduction.
What becomes of a YY genotype?
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.
How is a lethal allele maintained in a population?
A lethal allele can be maintained in a population if it is recessive and carriers of the allele have a survival advantage under certain conditions. This can result in heterozygote advantage, where individuals who are carriers of the lethal allele have some sort of beneficial trait that increases their overall fitness in the population. Additionally, genetic drift and mutation can also play a role in the maintenance of a lethal allele in a population.
A trait that is hidden?
The trait that is hidden is recessive trait.
What is the difference between a lethal and nonlethal contagion?
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=]
