Question
Complete the following paragraph to learn about X-linked inheritance.
expressed, men, sex-linked, repressed, X, Y, autosomal, two, one
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 X chromosome and not the Y chromosome.
That means that females can pass down diseased alleles to offspring through ____________ ____________ chromosomes, while males can pass down alleles through ____________ ____________ chromosome.
For this reason, it is more likely that ____________ are afflicted with sex-linked diseases, because whatever allele is carried on their ____________ ____________ chromosome is ____________ .
Explanation / Answer
1) Autosomal
Autosomal inheritance genes located on autosomes both males and females are affected with equal frequency by this mode.
2)Sex linked allele
Due to presence of allele on X chromosome both males and females are affected.
3) X chromosome
Female as passed down disease through X chromosomes if both the allele X from male and female are affected then the offspring can be diseased.
4) Y chromosome
Males can passed disease through X chromosome as they have only one pair of Y chromosome if it is defected there is no another Y chromosome to replaced it while in case of females they have two XX chromosomes.
5) Men
Most of sex linked disease are seen in men due to faulty Y chromosome which they recieve from male parent if it defected then there will be no other Y chromosome to repelace its funtion
6) Sex Linked, Expressed
In males the sex linked chromosome is expressed causing the disease condition
7) Autosomal Chromosome, repressed
the other chromosomes derived from female parent is repressed leading to disease
