Answer:
If one inherits a gene for a specific disease, and the gene is recessive, the disease is not always present
Step-by-step explanation:
If one inherits a gene for a specific disease, and the gene is recessive, the disease is not always present - This statement is true, if the allele of a gene is recessive, two copies of that allele are required in order for that to be expressed. If that recessive allele is disease-causing, then the disease will likely only be present if there are two copies of the allele. Hence, the presence of the recessive disease allele does not always mean the disease will occur
A mutation always causes a genetic disease - this is false, Mutations can be harmless. Even if a mutation is disease causing, the mutation could be recessive.
Dominant genes do not carry the codes for genetic disease - this is false. Disease-causing genes can be dominant. E.g. Huntington's disease.
If an Individual inherits a gene that carries a genetic disease, it is not possible for them to pass it on to their offspring - this is false. There is a 50:50 chance that an individual passes a particular allele onto each offspring.
