Huntingtons disease is inherited from your parents
Its Passed On From Your Parents Its Inherited
It can happen when both parents are a heterozygous
the chances are 1 out of 5 that you willget one to
Heterozygous means inheriting different genes from your parents. That is a heterozygous trait, not a homozygous one.
both parents could be A heterozygous or one A heterozygous and the other O
Children have similar characteristic's to their parents because when they are conceived, both of the parents genes unify to create a new set of characteristic'd depending on dominant and recessive traits. For example, Jane and Henry find out they are having a baby. Jane has homozygous blue eyes whilst Henry has heterozygous brown eyes. The chances are that their baby will either have 50% homozygous blue eyes or 50% heterozygous brown eyes.
AA could be either homozygous or heterozygous, depending on whether the individual inherited the same allele (A) from both parents (homozygous) or different alleles (Aa) from each parent (heterozygous).
Your child can be anything. It doesn't really matter what the parents are. Anything that runs through the family your child can be. The chances of being an O are very small but it is still possible. It depends on whether or not you are homozygous or heterozygous A. All O blood is genetically homozygous. If you are blood type AO then there is a 50% chance of Homozygous O (OO) and 50% chance of heterozygous A (AO). If you are Blood type AA then there is a 100% chance of heterozygous A (AO)
Huntingtons disease is a genetic/inherited diesease. It is caused by a faulty allele (a dominant one), which can be inherited by parents. Spontanoius mutations may also occur which would cause the faulty gene and therefore huntingtons disorder.
75%
There is 50% that children will be of negative blood type if parents are heterozygous positive. 25% if one parent is homozygous and other heterozygous. 0% if both homozygous.
