In Sickness and in Health

          The picture above is a model of Greg and Olga's pedigree's.  The first problem was myotonic dystrophy.  This disease is autosomal dominant.  An autosomal dominant disease can not skip a generation so they don't have to worry about passing it on to  their children.  The next disease they approached was factor VIII deficiency.  This disease is sex linked.  In a sex linked disease it can only be carried by the male because these diseases are on the X chromosome.  This means that the disease will only affect a boy if it is passed down.  The las thing they talked about was cystic fibrosis.  This is an autosomal recessive disease.  This means that it can skip generations.  Some people can be carriers of a disease like this.  It is a slight chance that their child can get it though.  Some races have more people that carry it over others too.  Their baby ended up having a 1 in 16, 560.  In the end the kid has a very slim chance of getting any diseases even though there are diseases in the family.
