Here is the way it works.

People from two different races have a child. The child will be a mix of those two races.

If that child has a baby with someone from either of those races then those children will share the genes of both parents but the children will have only 25% of the genes of one of the parents. If they have four kids it is likely that 3 will show signs of being mixed and one will not. That one will appear to be of one race.

If any of those children has children then of four children one will show signs of being mixed race and three will not. The three will appear to be of one racial background. However they do carry the genes of both races.

This means that somewhere down the line if they mate with another person who carries mixed racial heritage then there is a chance of the traits surfacing again.

How do people get Huntington's Disease?

HD is a genetic disease- you do not "catch it" from anyone. But is is inherited from a parent, just as you inherit hair color. One of the parents has a defective gene, which causes them to develop HD. If one of their children inherits that gene, they will also develop HD. However, if they do NOT inherit that gene, they cannot develop HD, and cannot pss it to their children.


If an individual expresses a dominant disease will the children always inherit the disease?

Not always. It depends if the individual is a hybrid- meaning they have both the dominant and the recessive gene. They can pass on the recessive gene instead of the dominant one, and assuming the other parents also passes on the recessive gene, the child will not inherit the disease.

What happen when both parents Carrie a ressavie of gene?

If both parents carry a recessive gene, there is a 25% chance that their child will inherit two copies of the recessive gene, leading to the expressed trait or condition. There is a 50% chance the child will inherit one copy of the gene and be a carrier like the parents, and a 25% chance the child will not inherit the gene at all. This is based on the principles of Mendelian genetics.


How can the cycle of huntingtons disease stop?

People that MAY have Huntington's can have a genetic test- IF they are positive for HD, they may choose not to have children- and no one will inherit the gene that causes HD.

If a grandfather has cystic fibrosis what is the chance his grandchild inherits it?

Cystic fibrosis is an autosomal recessive genetic disorder, meaning a child must inherit two mutated copies of the CFTR gene (one from each parent) to have the condition. If the grandfather has cystic fibrosis, he carries two copies of the mutated gene. The chance of the grandchild inheriting cystic fibrosis depends on the genetic status of the child's parents; if neither parent is a carrier of the CFTR mutation, the child cannot inherit the condition. If one parent is a carrier, the child has a 25% chance of being affected.


How do children inherit DMD?

Duchenne Muscular Dystrophy (DMD) is inherited in an X-linked recessive pattern, primarily affecting boys. The gene responsible for DMD, the dystrophin gene, is located on the X chromosome. Males have one X and one Y chromosome, so if they inherit the mutated X chromosome from their mother, they will develop the disorder. Females, having two X chromosomes, can be carriers if they inherit one mutated copy but usually do not exhibit severe symptoms due to the presence of a normal copy of the gene.


Can a person be a carrier of huntingtons disease and not show any symptoms?

Since HD is transmitted by a dominant gene, there are no "carriers", such as in sickle cell anemia. If you have HD, you can pass it along to your children. If you do not have HD, it cannot be passed on.


Which law states that organisms inherit two copies of each gene and donate one copy to each of their offspring?

Mendel's Law of Segregation states that organisms inherit two copies of each gene, and during gamete formation, these copies separate so that each gamete receives only one copy of the gene. This ensures that offspring inherit one copy of each gene from each parent.


What is the Mode of inheritance hemophilia?

Transmitted by a dominant gene. If that gene is inherited from either parent, the offspring will develop HD. If the gene is NOT inherited, then the offspring will not have HD- AND cannot pass the gene to their offspring.


What is the percentage of people in the world have Huntington's disease?

Becasue HD is carried on a dominant gene. Unlike recessive gene diseases, where you would have to inherit the gene from BOTH parents, with a dominant gene disorder- well, you will inherit one of two genes from the parent with HD. One carries HD, the other does not. Odds are 1 out of two, or 50%. For each child born to that parent.
