X-linked genes are found on the sex X chromosome. X-linked genes just like autosomal genes have both dominant and recessive types. Recessive X-linked disorders are rarely seen in females and usually only affect males. This is because males inherit their X chromosome and all X-linked genes will be inherited from the maternal side. Fathers only pass on their Y chromosome to their sons, so no X-linked traits will be inherited from father to son. Females express X-linked disorders when they are homozygous for the disorder and become carriers when they are heterozygous. An infamous recessive X-linked disorder is Hemophilia A. Hemophilia is a disorder where blood does not clot properly due to a shortage of clotting factor VIII. This disorder gained recognition as it traveled through royal families, notably the descendent's of Britain's Queen Victoria. X-linked dominant inheritance will show the same phenotype as a heterozygote and homozygote. Just like X-linked inheritance, there will be a lack of male-to-male inheritance, which makes it distinguishable from autosomal traits. One example of a X-linked trait is Coffin-Lowry syndrome, which is caused by a mutation in ribosomal protein gene. This mutation results in skeletal, craniofacial abnormalities, mental retardation, and short stature. X chromosomes in females undergo a process known as X inactivation. X inactivation is when one of the two X chromosomes in females is almost completely inactivated. It is important that this process occurs otherwise a woman would produce twice the amount of normal X chromosome proteins. The mechanism for X inactivation will occur during the embryonic stage. For people with disorders like trisomy X, where the genotype has three X chromosomes, X-inactivation will inactivate all X chromosomes until there is only one X chromosome active. X inactivation is not only limited to females, males with Klinefelter syndrome, who have an extra X chromosome, will also undergo X inactivation to have only one completely active X chromosome.
What else can I help you with?
If a characteristic is X-linked it?
If a characteristic is X-linked, it is located on the X chromosome. This means that the inheritance pattern of the characteristic will follow X-linked inheritance, and it can affect males more commonly than females because males only have one X chromosome.
What is the a pattern of inheritance in which certain characteristics carried on the X chromosome inherited from the mother are transmitted differently to her male and female offspring called?
This pattern of inheritance is called X-linked inheritance. It involves genes located on the X chromosome, leading to different inheritance patterns in males (who have one X chromosome) and females (who have two X chromosomes).
What is X-linked and Y-linked inheritance?
These are traits that are linked to the sex chromosomes. Only males can get Y-linked traits because only males have a Y chromosome. (Note: it's a bit more complicated that even this explanatin, but this is the general idea) If the father has the X-linked trait he can only pass it down to daughters. If the mother has the trait, the daughter might not have the trait because the father's donated X-chromosome might have a gene that masks it. If a son gets donated an X-chromosome from the mother with the trait, he will definitely show the trait.
What is the impact of the Hardy-Weinberg equilibrium on the inheritance patterns of X-linked recessive traits?
The Hardy-Weinberg equilibrium does not directly impact the inheritance patterns of X-linked recessive traits. Hardy-Weinberg equilibrium is a principle that describes the genetic makeup of a population when certain conditions are met, while X-linked recessive traits follow specific inheritance patterns based on the X chromosome.
Which type of inheritance involves genes found on the non-autosomal chromosomes?
These are called sex linked genes since they are on the genes that code for sex.
Which type of inheritance involves traits linked to a sex chromosome?
Sex-linked inheritance involves traits that are linked to genes on the sex chromosomes (X and Y). Traits carried on the X chromosome are typically expressed differently in males and females due to differences in the number of X chromosomes they inherit. Examples include color blindness and hemophilia.
What is the opposite of independence?
Linked gene inheritance. In humans, it is called x-linked inheritance; sex-linked inheritance is when the trait is carried on the X chromosome.
In X-linked recessive inheritance what sex is the affected?
There are 2 X-linked recessive inheritance where Only Male or Men are the only people who inherits these kind of trait.
What are the four complex patterns of inheritance?
Autosomal dominant, Autosomal recessive, X-linked recessive and X-linked dominant
If a characteristic is X-linked it?

What is sex-linked inheritance?
Sex-linked inheritance is things you(Or any other species) recieve from parents, diseases/disorders like being colorblind or having hemophillia are examples of a sex-linked trait. Males have XY and Females have XX, these traits can only occur on the X chromosomes meaning males have a much higer chance to recieve these effects.
What is X-linked and Y-linked inheritance?
These are traits that are linked to the sex chromosomes. Only males can get Y-linked traits because only males have a Y chromosome. (Note: it's a bit more complicated that even this explanatin, but this is the general idea) If the father has the X-linked trait he can only pass it down to daughters. If the mother has the trait, the daughter might not have the trait because the father's donated X-chromosome might have a gene that masks it. If a son gets donated an X-chromosome from the mother with the trait, he will definitely show the trait.
What are the names of some genetic inheritance patterns?
Some common genetic inheritance patterns include autosomal dominant, autosomal recessive, X-linked dominant, and X-linked recessive. These patterns describe how traits are passed down from parents to offspring.
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.
What is the impact of the Hardy-Weinberg equilibrium on the inheritance patterns of X-linked recessive traits?
The Hardy-Weinberg equilibrium does not directly impact the inheritance patterns of X-linked recessive traits. Hardy-Weinberg equilibrium is a principle that describes the genetic makeup of a population when certain conditions are met, while X-linked recessive traits follow specific inheritance patterns based on the X chromosome.
What are the probable mode of inheritance from a pedigree diagram showing phenotypes?
The modes of inheritance are y-linked, x-linked, and mitochondrial. Inherited traits can then be recessive, dominant, or autosomal depending on how they are inherited.
