Genetic
The Huntington's gene is inherited as a dominant gene. This means that a person only needs to inherit one copy of the mutated gene from either parent to develop the condition.
a gene
Phenylketonuria (PKU) is inherited when both parents are carriers of the gene. Since it is a recessive gene, there is a 25% chance that any baby conceived by two people carrying the PKU gene will have PKU.
In humans, alleles for each gene are inherited from both parents, with each parent contributing one allele for each gene. This means that individuals have two alleles for each gene, one inherited from the mother and one from the father. The combination of these alleles determines the individual's traits and characteristics.
gene
When a gene is linked to a chromosome, it means that the gene is physically located on that chromosome. This means that the gene is inherited along with the chromosome it is located on, and may be inherited together with other nearby genes on the same chromosome.
A gene mutation can be caused by radiation. A gene mutation can also be inherited from family members, such as grandparents and parents.
That gene is said to be dominant. Dominant genes will be expressed over recessive genes in a heterozygous individual.
