You can be a carrier of a recessive gene as part of your genotype.
She is a carrier of hemophilia but does not have the condition
heterozygous
If their genotype contains both a dominant and a recessive allele for a trait.
if someone is a Heterozygous carrier of Tay-Sachs they would have to be Tt. Because TT is Homozygous.
The genotype of a person with CF is cc. The genotype of a carrier of a CF mutation is Cc.
Mary's father is normal and has a normal genotype XY while her mother is the carrier of hemophilia and has one X of her genotype infected i.e. she is X*X.
I think no. It's caused by a recessive gene so if a person has albinism their genotype can only be recessive, recessive ---> AA (small a small a or whatever you call it). No other genotype will mean that person has Albinism, like if it has at least one big A, that means it's just a carrier of albinism.

Genotype
As long as a persons genotype consists of at least one recessive gene, they can pass it on to offspring to give them the disease, which makes them a carrier. Since this persons genes are both recessive, it is definite that they will pass on the recessive gene.
A genetic carrier has a dominant and a recessive version of an allele. Normally, the term genetic carrier is used in relation to genetic illnesses where two copies of the recessive allele cause that illness. Therefore, a carrier does not have the illness themself (as the dominant, non-disease allele is expressed over the recessive allele). However, they have the ability to create an offspring who has the double recessive genotype and therefore has the condition if they mate with another carrier or someone who is double recessive (who has the disease).
