What an allele?
An allele is an alternative form of a gene that is found at the same location on a chromosome.
Is Huntingtons disease non disjunction?
No. Hemophilia is the result of any of a number of mutations such as reversals, translations, deletions, etc. These mutations need to have occurred in a very specific segment of the coding found on the X chromosome. The replication of that X chromosome however is unaffected with the exception that the mutation on it is replicated as well.
What is Unit of inheritance present on the chromosome is called?
The unit of heredity found on a chromosome is called a gene.
Why is hemophilia more common in males than women?
this disease is caused by a recessive allele that is found only on the x chromosome. a human female has two x chromosomes. a human male only has 1 x chromosome. therefore, a male needs only one recessives allele to have hemophilia, while a female needs two recessive allele. as a result, hemophilia is much more common in males.
What is an allele inherited on a sex-chromosome?
A gene found on a sex chromosome is known as a sex-linked gene. Alleles are the different forms of a gene.
Is achondroplasia y linked?
It isn't - it's found on one of your autosomes: the 22 non-sex chromosomes. It's found on the fourth chromosome.
Who found the gene for huntingtons disease?
The hunt for the gene was accomplished by the work of many dedicated researchers working cooperatively.
How does hemophilia progress?
Hemophilia is a recessive allele condition. Men can get hemophilia alot easier than women as the allele is found on the XY Chomosome pair. With men. they do not have the extra "tail" on the Y chromosome compared to the XX with a female. If the person has the recessive allele on the X chromosome and this person is male, they will be a hemophiliac as they do not have a 'pair' allele which could be dominant to stop the condition expressing itself. On a female, if there is a recessive (hemophilia) allele on one of the X chromosomes but on the other is a Dominant (normal) allele then she will be a carrier of the faulty gene but will not suffer from the condition herself. If the female have a recessive (faulty) gene on each of the XX chromosomes, then she will be a sufferer of the disease.
What chromosome is polycystic kidney disease found?
It is a mutated gene called PKD1 located on chromosome 16.
Sex linked traits are primarily found in?
Males, because they have one X chromosome, in which the traits are carried on. Therefore, if they have one allele they will have that trait because they do cannot have another allele to affect it.
What chromosome number is affected by alzheimer's disease?
Chromosome numbers: 1, 14, 19, and 21 are affected by Alzheimer's disease.
What are some examples of allele's?
Multiple alleles means that for a specific locus on a chromosome there can be 3 or more forms of that gene (allele). Only one allele can be inherited because they are found on homologous chromosomes. Height is not a multiple allele because it is associated with many genes on several chromosomes (plus environmental factors) so this would be polygenic inheritance. Multiple allele trait is the ABO group. The allele for A B or O (3 alleles ) is found on the same locus, therefore only one of them could be inherited EXAMPLE: DNA
