Alcoholism is not inheritable.
One of the allels for a trait to it's offspring.
Segregation
The unit of heredity that passes on traits from parent to offspring is a gene. Genes are segments of DNA that encode specific instructions for the development and functioning of an organism. They are inherited from parents and determine characteristics such as eye color, blood type, and susceptibility to certain diseases.
If one parent has a dominant trait and and another parent has a recessive trait, then the recessive trait gets hidden while the dominant trait gets shown.
The probability that a parent carrying a dominant trait will pass that trait on is a 50% chance with each pregnancy
You inherent gene from your parent and they give you trait.
100% of the offspring will display the dominant trait because the homozygous dominant parent can only pass on the dominant allele. The offspring will inherit one dominant allele from the dominant parent and one recessive allele from the recessive parent, resulting in a heterozygous genotype expressing the dominant trait.
One parent has a recessive trait. For example: One parent has blood type AB, the other has blood type OO.
It is a dominant genetic trait. If you get a gene for it from either parent, you will have this trait.
In genetics, if one parent carries a recessive trait, it can only be expressed in the offspring if both parents contribute the recessive allele. If "parent one" is crossed with another parent that does not carry the recessive trait, the offspring may inherit the dominant trait. However, if the second parent also carries the recessive allele, there is a chance that the offspring could display the recessive trait depending on the genetic makeup of both parents. The reference to "aspirin" seems unclear in this context; if it pertains to a specific trait or condition, please provide more detail.
Trait
a true breeding plant always produces offspring with the same trait as the parent(s).
