Question

Complete the following paragraph to learn about x-linked inheritance. Options may be used more than once. two sex-linked X men women y one repressed trait autosomal Sex-linked alleles have a different pattern of inheritance compared to those found on __________ chromosomes. This is because on ________ alleles, the allele is only carried on the _________ chromosome and not the __________ chromosome. That means that females can pass down mutated alleles to offspring through __________ X chromosome(s), while males can pass down alleles through ___________ X chromosome(s). For this reason, it is more likely that _________ are effected with sex-linked diseases, because whatever allele is carried on their _________ X chromosome(s) is expressed.

Explanation / Answer

Sex linked alleles have a different pattern of inheritance compared to those found on autosomal chromosomes.

This is because, on sex linked alleles, the allele is only carried on the X chromosome and not the Y chromosome.

That means that females can pass down mutated alleles to offsprings through two X chromosomes while males can pass down alleles through one X chromosome.

For this reason, it is more likely that men are affected with sex linked diseases because whatever allele is carried on their one X chromosome is expressed.
