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 is the probability that a pregnancy will abort if the mother and father both carry a lethal recessive allele?
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.
What is dominant lethal allele?
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.
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.
A trait that is hidden?

How is a lethal allele maintained in a population?
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.
What is the difference between a lethal and nonlethal contagion?
