Can a person be a carrier for a dominant genetic disorder?
Anyone can be a carrier of a recessive genetic disorder (as long as it is not associated with the sex chromosomes) no matter what their gender since "carrier" refers to an individual that is heterozygous for the recessive allele and therefore phenotypically normal. Specifically, sexlinked genetic disorders can be "carried" by a heterozygous female but males (having only one X chromosome) cannot. Males will either be free of the defective gene or be affected.
How is a carrier different from a person who has genetic disorder?
A carrier means that you have the gene for the disorder, but because the gene is recessive (meaning that it only shows when you have two recessive genes) and you obviously have a dominant gene as well, you won't show the disorder. Someone who actually has the disorder has two recessive genes. D = dominant gene r = recessive gene Dr = carrier, no signs rD = carrier, no signs DD = not a carrier, no signs rr = has the disorder
How is carrier different from a person that has a disorder?
The carrier typically remains unaffected by the disorder.
A carrier of a genetic disorder who does not show symptoms is most likely to be to transmit it to offspring?
A carrier of a genetic disorder who does not show symptoms is most likely to be heterozygous for the trait and able to transmit it to his offspring. The term heterozygous refers to a pair of gene with one dominant trait and one recessive trait.
A person who has inherited the autosomal recessive disorder called?
A person who has inherited an autosomal recessive disorder will have two copies of the mutated gene, one from each parent. This results in the individual expressing the disorder. Symptoms can vary depending on the specific disorder.
What is a person who has recessive allele for a trait but does not express that trait?
They would be considered a carrier. ------------------------------- More precisely a heterozygote. A carrier would imply that the recessive trait causes disease.
What is the genotype of a person who is a carrier of a autosomal recessive trait?
The genotype of a person who is a carrier of an autosomal recessive trait is typically heterozygous, meaning they carry one copy of the recessive allele and one copy of the dominant allele for that trait. This would be represented as Aa, with the lowercase "a" representing the recessive allele.
Is a person who is homozygous recessive for a recessive genetic disese a carrier?
As long as a persons genotype consists of at least one recessive gene, they can pass it on to offspring to give them the disease, which makes them a carrier. Since this persons genes are both recessive, it is definite that they will pass on the recessive gene.
What is the genotype of a carrier of recessive disorder?
A carrier is someone who does not have a disorder but carries the allele on to offspring.
What is a heterozygous person called?
A heterozygous person is called a carrier for the specific trait or gene they carry. This means they have two different alleles for a particular gene, with one dominant and one recessive allele. It is important to note that being heterozygous for a genetic disorder does not necessarily mean the individual will exhibit symptoms of the disorder.
Is Tay Sachs dominant or recessive?
Tay Sachs is a recessive genetic disorder, meaning that a person needs to inherit two copies of the mutated gene (one from each parent) to develop the condition. If a person inherits only one copy of the mutated gene, they are considered a carrier but do not show symptoms of Tay Sachs.
Is a person who is homozygous recessive for a recessive genetic diseases a carrier?
No, because he or she cannot pass the gene on to his or her offspring (because he or she does not have a copy of the gene).
