Question

A woman with albinic father marries an albinic man. The proportion of her progeny is:

Answer 1

Albinism is an autosomal recessive disease, that is, two recessive genes are required to bring about the disease.
Let the dominant gene be A and recessive gene be a.
The genotype of the father is aa. 
The genotype of the daughter is Aa (As it isn't mentioned that she has the disease)
The genotype of her husband is aa (As he is affected)
Now, when the daughter and her husband have children, the types of genotype for the progeny possible are

Aa Aa aa aa

That is, there is 50% chance for the progeny to be affected by albinism.

Answer 2

A woman with albinic father marries an albinic man. The proportion of her progeny is albinic.

Explanation:  

• Albinism is a recessive inherent disorder. In this a person to be affected should contain 2 copies of affected alleles.  

• Since both the parents have 2 copies of infected alleles there is 100% chances that the kid also will be albinic.  

• This disease is widely characterised by impaired synthesis of melanin in the body.
