Q. No.A couple comes to you for genetic counselling. Both have a sister affected with albinism but all other members are normal. Your advice regarding the risk of their child being affected with albinism would be:
| 1. | They must both be heterozygotes so their risk of having an affected child is ¼. |
| 2. | They might both be heterozygotes so they should get tested to see if they carry the disease allele or not. |
| 3. | Since neither one of them is affected, they are not at risk of having an affected child. |
