How are sex linked genes expressed differently in the phenotypes of males and females?
i dont know.. im looking for the answer... XD
Sex linked disorders are caused by males' having?
Sex-linked disorders are caused by genes located on the sex chromosomes, particularly the X chromosome. Since males have only one X chromosome, mutations in genes on this chromosome are more likely to be expressed in males compared to females who have two X chromosomes. This is why sex-linked disorders are more commonly seen in males.
X-linked traits are rare in females?
X-linked traits are rare in females because they have two X chromosomes, which allows for compensation of any defective genes on one X chromosome with the normal genes on the other X chromosome. In contrast, males only have one X chromosome, so any defective gene on that chromosome will be expressed. This is why X-linked traits are more commonly observed in males.
What are sex-link genes and their effects?
Since males are the only sex to have a y chromosome, only males can get genes that are linked to the Y chromosome. This means that some genetic diseases and conditions are more likely to be male such as color blindness.
What is a trait that is passed from parent to child on the X chromosome called?
Recessive traits on X chromosome are expressed in males because they have only one copy of X chromosome. If they have any recessive gene it will be expressed. In female both the genes should be recessive then only the recessive character will be expressed.
Which genes are expressed even when present on only one chromosome?
Genes located on the X chromosome in males are expressed even when present on only one copy. This is because males have only one X chromosome and it is always active. In females, one of the two X chromosomes is randomly inactivated during early development, ensuring balanced gene expression.

Why is colour blindness more common in males?
The genes that produce photopigments are carried on the X chromosome; if some of these genes are missing or damaged, color blindness will be expressed in males with a higher probability than in females because males only have one X chromosome (in females, a good gene on only one of the two X chromosomes is enough to yield the needed photopigments).
What are the genes that travel on the X chromosome and how do they impact inheritance patterns?
Genes that travel on the X chromosome are called X-linked genes. These genes can impact inheritance patterns because males have only one X chromosome, so any genetic mutations on that chromosome will be expressed. In contrast, females have two X chromosomes, so they may carry a mutated gene on one X chromosome but have a normal copy on the other, reducing the likelihood of expressing the mutation. This can lead to different inheritance patterns for X-linked traits between males and females.

What alleles do females carry but not males?
Females carry two copies of the X chromosome, while males carry one X and one Y chromosome. This means that females can have two different alleles for genes located on the X chromosome, while males can only have one allele for those genes.
What is a trait that is passed from parent to child on the X chromosome called?
Recessive traits on X chromosome are expressed in males because they have only one copy of X chromosome. If they have any recessive gene it will be expressed. In female both the genes should be recessive then only the recessive character will be expressed.
A gene located on the X or Y chromosome is a?
Genes located on the X or Y chromosome are referred to as sex-linked genes. This is because the inheritance of these genes is dependent upon the sex of the individual. For example, only males can inherit genes located on the Y chromosome (because males have XY and females have XX).
Under what condition is a single recessive allele expressed in a male?
A single recessive allele will be expressed in a male if he inherits that allele on his only X chromosome, as males have one X and one Y chromosome. This is because the presence of the recessive allele on the X chromosome has no dominant allele to mask its expression.
Why is colorblindness found to be inherited into males more than females?
Most color deficiencies are sex linked, meaning the defective genes are on the sex chromosome. In this case, the X chromosome is affected. Since males only have one X chromosome, all males with this particular defective genes will have this condition. Females have 2 X's, it's unlikely that both X's have bad genes at the same time.
