What is an inherited disorder that appears more often in males than females?
Those transmitted on the Y chromosome (girls don't have a Y) Examples include reg/green color blindness.
What are the unique facts about color blindness?
Not being able to see color in some cases. Mild color blindness might just be an inability to distinguish between colors like green and red. That is sometimes the case, not always. Did you know that 99% of all color blind people are not actually color blind, but color deficient? Does that help?
Is blindness a disease or a disorder?
Blindness can be caused by many diseases, but is not a disease. Therefore, it is a disorder.
Why can a man who has sex-linked disorder pass the disorder to his daughter but not to his sons?
Sex-linked disorders are passed on the X chromosome. The man supplies the Y chromosome to his sons so the disorder cannot be passed on to the sons. But the man gives his daughter an X chromosome so the disorder can be passed on to her.
This pedigree I'm working with shows the inheritance of a sex-linked disorder such as color blindness Is the father A affected or not affected by this disorder?
First of all, it important to understand that the male chromosome (the Y chromosome) basically only contains the genetic material that is required to make someone male. There isn't room on it for much more. So, the sex linked disorder genes are usually only present on the X chromosome. These genes are also usually recessive traits. So, they only manifest themselves when there is not a dominant gene of the same type to override them. This will most often happen in a male where they will only have one copy of the gene on the X chromosome. Thus, traits like red-green color blindness that are carried by the X chromosome usually only manifest themselves in the male offspring of the parents and they will receive them from their mothers. Females can only inherit these traits if they are passed on by both parents. In this case, the father WILL have the trait and the mother will be a carrier at the very least.
What disorder is likely to be inherited by more males than females?
Those transmitted on the Y chromosome (girls don't have a Y) Examples include reg/green color blindness.

What type of genetic disorder is PKU?
PKU is described as an inherited, autosomal recessive disorder.
Why are sex linked disorders seen in mostly males?
Males are most likely to have the disorder.

Red-green color blindness is a human genetic disorder cause by?
Color blindness is a sex-linked genetic disorder. The reason that it is more prevalent in males is because the disorder is linked the the X-chromasome. If a male inherits an X chromosome that is defective, then they will be color blind. However, a female has two X chromosomes which means she can receive a defective chromosome and only be a carrier of the mutation. If she receives two defective x chromosomes, she will be colorblind.
Down syndrome is an example of?
Chromosome Disorder
Is blindness a disease or a disorder?
Blindness can be caused by many diseases, but is not a disease. Therefore, it is a disorder.
Is Down syndrome a genetic disorder or a chromosome disorder?
Down syndrome is a chromosomal disorder. It is caused by having 1 extra chromosome (chromosome 21).
What causes color blindness?
This trait is carried on the X chromosome and is a recessive trait so that only men can get it but it is carried by women.Color blindness is caused entirely by hereditary traits. So in a nutshell, you can't naturally "get" color blindness during your lifetime, unless if you remove your "cones." However, if you are a male carrier of the colorblind trait, your chances of being born color blind are higher than if you are a female carrier.Color blindness most often happens because of a genetic disorder. This happens when a section of DNA is copied incorrectly from parent to offspring.Colorblindness is caused by three cones in the back of the eye.Three different colors.If these cones are not working properly,then you have trouble telling the difference between different colors.Ex.blue and purple.You become colorblind when the cones in your eye bend or misshape and stop workingMost color blindness is caused by an inherited genetic defect where the functioning of the color receptive cones in the retina is deficient - or where the cones are absent altogether. It is most commonly inherited from mutations on the X chromosome. There are different genetic defects that cause different types of color blindness. Some manifest at birth, while others are progressive, i.e. persons with some defects gradually lose their ability to distinguish some or all colors. Because males have one X chromosome and one Y chromosome while females have two X chromosomes, males are at greater risk for having color blindness. If a woman inherits a normal X chromosome in addition to the one that carries the mutation, she will not display the mutation. Men do not have a second X chromosome to override the chromosome that carries the mutation.
Which one is not a genetic disorder color blindness hemophilia cystic fibrosis down syndrome?
Down syndrome is a polyploidy (three chromosome 21s)and is considered to be a somatic disorder. The other three are genetic because they are present in the form of a defective allele on achromosome.
What is a sex-linked linked genetic disorder?
color blindness is one
