there is a 50% chance that an offspring will also have the abnormal gene. As the mutation is located on one of the autosomes, the sex of the offspring will not affect the outcome of the disease or disorder. A common example of a disorder caused by autosomal dominant genes is Huntington’...
How dominant or recessive each gene expression is and how they effect the final phenotype varies based on the interactions of the genes. The term for these interactions and their resulting phenotypes is called epistasis.Answer and Explanation: Complementary genes are a form of epistatic gene interact...

Autosomal dominant genetic diseases are hereditary and occur when a defective gene is passed from one parent to a child. The word 'autosomal' refers to chromosomes (structures in our cells that hold genes) that are not sex chromosomes.
So there is no such thing as dominant or recessive genes: We call a trait dominant if having just one copy of it has the noticeable effect, and we call it recessive if both copies are required to produce the effect. Eye Color For example, here’s how the above explanation applies to ...
Variations in the sequence of these genes are called alleles, and differing alleles may interact in a variety of ways depending on the chromosome on which they are located, resulting in a wide range of phenotypic effects.One allele may be dominant while the other is recessive, eye color often...

Heredity is complex. Given all the DNA in our genetic code, and given that we get stuff from mom and dad, there are almost infinite possible combinations of traits. Some traits aredominant, meaning they are more likely to be expressed. Some traits are recessive, meaning that they are less...
