How is a carrier different from a person who has genetic disorder?

Answer 1

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

Answer 2

A carrier carries the defective allele on one of his/her homologous chromosomes, and the normal allele on the other homologous chromosome. If the normal allele is dominant, then the carrier does not have the genetic disorder. However, if the carrier has a child with another carrier, it is possible that the child will inherit both parents' defective alleles and have the genetic disorder.

Answer 3

A carrier is a person who has one copy of a gene mutation for a genetic disorder but does not show symptoms themselves. A person with a genetic disorder has two copies of the gene mutation and will exhibit symptoms of the disorder. Carriers can pass the gene mutation on to their children, increasing the risk of the disorder being present in future generations.

Answer 4

if you are a carrier, you do not have the disease, but you still can pass it on to your children. if you have the genetic disorder, then you are affected by the disease.

Answer 5

A carrier doesn't show the disease symptoms

Answer 6

the disorder allele is recessive

Answer 7

A carrier is infectious.
