Because males have an X and Y chromosome. If the trait is X-linked (recessive), there is nothing to mask the expression. On the other hand if a woman has an x-linked recessive allele and a dominant one, the dominant trait is the one that will be expressed.

What are three sex-linked diseases?

Three examples of a sex-linked disease are; Hemophilia, Wiskott-Aldrich syndrome, and androgen insensitivity syndrome. HIV, gonorrhea, and syphilis are examples of sexually transmitted diseases, which is something totally different.


Why are sex linked recessive conditions more likely in males then females?

Sex-linked recessive conditions are more likely to occur in males because they only need to inherit one copy of the affected gene in order to exhibit the condition (as they have one X chromosome). Females, on the other hand, have two X chromosomes, so they need to inherit two copies of the affected gene to exhibit the condition.


How do you know if a trait is sex linked dominant or sex linked recessive?

A trait is sex-linked dominant if it appears in every generation and affects both males and females. It is sex-linked recessive if it skips generations, more common in males, and passed from carrier females to affected males. Mendelian inheritance patterns can help determine if a trait is sex-linked dominant or sex-linked recessive.


I what conditions is caused by a sex-linked gene klinefelters syndrome down syndrome muscular dystrophy?

Klinefelters is sex chromosome trisomy. Down Syndrome is trisomy. One of the most common forms of MD is sex-linked and affects boys more frequently than it does girls.


What is the process for calculating probabilities in pedigrees of X-linked conditions?

To calculate probabilities in pedigrees of X-linked conditions, you need to consider the inheritance pattern of the X chromosome. Males inherit their X chromosome from their mother and their Y chromosome from their father, while females inherit one X chromosome from each parent. By analyzing the family tree and identifying carriers and affected individuals, you can determine the likelihood of passing on the X-linked condition to future generations. This involves understanding the chances of a carrier mother passing on the affected X chromosome to her children, and the different probabilities for males and females inheriting the condition.


Is breast cancer a sex linked gene?

absolutely not, these cancer cells can attack both men and women I don't know the answer to the question, but the previous answer, "absolutely not, these cancer cells can attack both men and women" does not answer it. Sex-linked traits/genes can appear in both men and women.


What is a is a sex-linked trait?

If a gene is found on the X chromosome ( and, less commomly on the Y chromosome), it is said to be a sex-linked trait. Because the gene controlling the trait is located on the sex chromosome, sex linkage is linked to the gender of the individual. Usually such genes are found on the X chromosome. The Y chromosome is thus missing such genes (See Diagram above.). The result is that females will have two copies of the sex-linked gene while males will only have one copy of this gene. If the gene is recessive, then males only need one such recessive gene to have a sex-linked trait rather than the customary two recessive genes for traits that are not sex-linked. This is why males exhibit some traits more frequently than females.


How x linked traits affect the inheritance of sex linked traits?

Females have 2 X chromosomes so the X-linked genes follow the same rules of dominance & recessivity as the genes on the autosomes.


Do males or females often suffer from bad sex-linked traits?

Often is certainly the wrong word. Such 'bad sex-linked traits' are considered rare.


How are the alleles for sex-linked traits inherited?

Sex-linked traits are inherited through alleles located on the sex chromosomes, specifically the X and Y chromosomes. In humans, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). Since sex-linked traits are carried on the X chromosome, they are inherited differently in males and females. Males inherit sex-linked traits from their mothers, as they receive their only X chromosome from their mother. Females can inherit sex-linked traits from both parents, as they receive one X chromosome from each parent.


What gender inherits the y-linked trait?

male, their sex chromosomes are XY, females are always XX
