A deadly genetic disease that is cause by a recessive allele in a sex-linked gene can basically never strike women (save for a new mutation). Why not?
Homework Answers
Because a women gets its dominant X allele from male which is normal, and gets its recessive allele from carrier female. So a female can be carrier of the x-linked recessive disease but cannot be diseased.
As this gene require homozygous recessive condition to express itself, which basically is not present innormal females

39 of 45 Why are sex-linked conditions more common in men than in women? Women simply do not develop the disease regardless of their genetic composition. Men need to inherit only one copy of the recessive allele for the condition to be fully expressed. The sex chromosomes are more active in men than in women. Men acquire two copies of the defective gene during fertilization. Men have more linked genes.

10. In humans Wiskott–Aldrich syndrome (WAS) is a rare sex-linked recessive disease characterized by eczema, thrombocytopenia (low platelet count), immune deficiency, and bloody diarrhea. This disease is due to a sex-linked recessive allele. a. Examine the statement below. Is this statement true or false? Why? Explain. Boys usually inherit sex-linked recessive disorders from their fathers. Sarah is healthy and but her brother has WAS. Her mother and father both have healthy phenotypes. Sarah marries Fred, a healthy man without WAS....

10. Red green colorblindness is an X-linked recessive disease. That means that it is carried on the X chromosome, so men have just one copy of the gene while women have two. In women, both copies must be the recessive disease allele in order to show the disease phenotype, but because men only have one allele, just one recessive allele causes the disease phenotype. Matt and Kate both have normal vision, but Kate's father is colorblind. Use X for the...

Green-weakness partial color blindness, or deuteranomaly, is a sex-linked recessive trait. The green-weakness allele, g, is recessive to the allele for normal color vision, G. Another form of abnormal vision is total color blindness which is due to an autosomal gene, t, which is recessive to its counterpart allele, T, for normal vision. A man with a normal phenotype marries a woman with green-weakness partial color blindness. Both individuals are heterozygous for autosomal color blindness. What phenotypes and phenotypic frequencies...

In drosophila (fruit flies), male is the heterogametic sex. This means that if a recessive disease is linked to the X chromosome, males will express the disease when: O both mother and father pass the allele that codes for the disease O any of the parents express the disease. O the mother passes the allele that codes for the disease O any of the parents present the allele

*why do sex-linked traits (X- linked traits) such as red-green colorblindness (which is recessive) display a different pattern of genetic inheritance from autosomal recessive traits? and does it make a difference whether the sex-linked trait is dominant rather than recessive? how? *what are the chances a boy will be colorblind if his mothers father was color blind?

3. Sickle-cell disease is a genetic condition caused by an autosomal recessive allele which al- fects one in every 500 African American children born in the U.S. One in every ten African Americans is a carrier for the recessive allels. Although sickle cell disease is caused by a single human gene, it is expressed through many different effects throughout the body. The presence of a recessive sickle-cell allele in humans causes the red blood cells to produce abnormal hemoglobin protein...
