When these genes are located on our sex chromosomes, the corresponding traits are known as sex-linked traits Sex-linked genes are found on our sex chromosomes. An example of this can be seen in hemophilia. Sex-linked character. With regard to Drosophila eye color, when the P 1 male expresses the white-eye phenotype and the female is homozygous red-eyed, all members of the F 1 generation exhibit red eyes.

In humans, the term generally refers to traits that are influenced by genes on the X chromosome. One of these genes is the "SRY" gene called the "sex determination region Y gene.

And so the reason why he exhibits hemophilia is that there is no other X chromosome with the dominant allele to be dominant over the hemophilia allele. Conclusion: The sex chromosomes carry Sex-linked traits In recessive sex-linked traits, the mother is usually the silent carrier Affected individuals are more often males due to one X linked chromosome Missing or extra chromosomes can produce genetic disorders.

Leave them in the comment section below. If the sperm cell contains a Y chromosome, then the resulting zygote will be XY or male.

Several traits, including red-green colour blindness , arise from the interaction of genes that are located on the X chromosome. Carrier females can manifest mild forms of the trait due to the inactivation of the dominant allele located on one of the X chromosomes.

What are some examples of sex linkage? See Article History. Females must inherit recessive X-linked alleles from both of their parents in order to express the trait. This is why males exhibit some traits more frequently than females.
