These reproductive patterns can yield carrier, affected, and normal children. The possible results are: o Normal males o Affected males o Normal Females o Affected females o Carrier females But, you will notice that there is no possibility of having a carrier male. An affected male automatically carries the disease, but cannot carry the disease without being affected by it. As mentioned above, this is because a male who is carrying the disease will be affected by it because he is carrying it on his only X chromosome. Likewise, in the rare occurrence that a female is affected with an X-linked disease, she will be a carrier of it. |
