Lets say that your dad has brown hair, and your mom has red hair. The brown would be the dominant gene (B) and the red hair would be recessive (b). So you would most likely have brown hair since it is dominant. But if both parents had red hair (b) it would still be recessive. So the genes you inherited would be bb. You would then have red hair. If they both had brown (BB) then you would have brown. But if your parents did have brown and red hair, then you would have Bb. You would still then have brown hair since brown is the dominant color. But then if you have children, They would get one of each, so if you married someone with red hair, there is a possibility of your child of having red hair. I am not entirely sure if this answers the question, so I am sorry if it didn't. Hope it helped.
Genes that are expressed even when inherited from only one parent are called dominant genes. These dominant genes typically mask the expression of recessive genes when present. Examples of dominant genes include the gene for brown eyes and the gene for attached earlobes.

Is the Huntingtons gene inherited as a dominant or ressisive gene?
The Huntington's gene is inherited as a dominant gene. This means that a person only needs to inherit one copy of the mutated gene from either parent to develop the condition.
What are alleles and how are they inherited from parent cells?
Alleles are alternative forms of a gene that can occupy the same position on a chromosome. When an organism inherits alleles from its parents, one allele is typically inherited from each parent. This process occurs during sexual reproduction, where each parent contributes one allele to the offspring.
When both alleles of gene are different what is individual?
The individual is heterozygous for that gene. This means they have two different alleles for the gene, one inherited from each parent. The individual will express the dominant allele if present.
What term defines a gene made up of two diffrent alleles?
A gene with two different alleles is called a heterozygous gene. This means that an individual has inherited two different versions of the gene, one from each parent.
How many alleles is a gene controlled by?
A gene is controlled by two alleles, one inherited from each parent. These alleles can be the same (homozygous) or different (heterozygous), influencing the expression of the gene and determining an individual's specific traits.
Is the Huntingtons gene inherited as a dominant or ressisive gene?
The Huntington's gene is inherited as a dominant gene. This means that a person only needs to inherit one copy of the mutated gene from either parent to develop the condition.
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.
Is inherited from only one parent the offspring Will have that genetic?
Recessive gene
What are characteristics passed from parent to offspring called?
genetic traits
When a gene inherited from one parent masks the expression of the gene inherited from the other parent that gene is said to be?
That gene is said to be dominant. Dominant genes will be expressed over recessive genes in a heterozygous individual.
How do traits get inherited?
Through genetics, you have two alleles(different versions for a gene) for each gene, one from each parent
Which parent passes parkinsons disease?
A parent may only pass the gene for Huntington's if they HAVE Huntington's. It is transmitted on a Dominant gene. If you do not HAVE Huntington's. it is not possible to pass it to your children. My wife inherited the gene from her father. Our sone and daughter inherited from their mother. It can be from either parent, but only if that parent has HD.
How many many parents have to have the allele for huntingtons to affect there children?
Either parent. Since HD is carried on a dominant gene, if the gene is inherited from either parent, the offspring will develop HD.
Why can Cystic fibrosis be inherited even if neither parent has the disease?
Cystic Fibrosis is an example of a disease inherited as an autosomal recessive genetic disorder. Both parents of a baby who has Cystic Fibrosis have one abnormal recessive gene and one normal dominant gene and are therefore, Cystic Fibrosis carriers. Carriers are said to be heterozygous because they contain one normal copy of the gene and one abnormal copy. A baby who inherits cystic fibrosis has inherited the abnormal gene from both parents and is therefore said to be homozygous recessive.
How many alleles does each person have for an autosomal gene?
Each person has two alleles for an autosomal gene, one inherited from each parent. These two alleles together determine an individual's genotype for that gene.
How' linkage is used to make gene maps?
A gene map is a chromosomal map, which shows the location of genes. Based on inherited genes, a linkage can be used to create a gene map.
How is Treacher Collins Syndrome passed from parent to offspring?
This syndrome is caused by a new mutation in one or two genes in 60% of the cases. These are not inherited. The other 20% are inherited if one parent carries the mutated gene. In the final 20% both parents have to carry a different gene for their offspring to have the syndrome. In this case neither parent show any signs or symptoms.
