Many genotypic and phenotypic characteristics are linked to the X chromosome. Some of these are caused by X-linked traits, whereas others are due to X chromosome inactivation. Drag the labels on the left to the appropriate category on the right.

Answer:

X chromosome inactivation:

- Calico cats have patches of black and orange fur

- "Heterozygotes" can express the recessive phenotype

- Rett syndrome is not always fatal in females  

- Barr bodies

X linked traits:

- Color blindness is more common in men  

- Hemophilia  

Explanation:

X chromosome inactivation refers to the mechanism in which one X chromosome is randomly inactivated during early embryonic development in female mammals. The inactivated (silenced) X chromosome is condensed into a structure called Barr body. In cats, the gene encoding for the orange/non-orange fur coloring is X-linked, thereby X inactivation explains why most calico cats (i.e., those cats that have a color pattern with orange and black spots) are female. Moreover, Rett syndrome is a neurodevelopmental disorder caused by a mutation in the X-linked MECP2 gene, and therefore this disorder is much more serious in males. On the other hand, color blindness is more common in men because males have only one X chromosome. In the same way, hemophilia, which is a disorder caused due by a mutation in one gene required for synthesizing one clotting factor, is more common in males than in females because the gene responsible for this disorder is located on the X chromosome.

X chromosome inactivation:

  • Calico cats have patches of black and orange fur
  • Heterozygotes" can explicit the recessive phenotype
  • Rett syndrome isn't continually deadly in ladies
  • Barr bodie
  • X connected traits:
  • Hemophilia
  • Color blindness is greater not unusualplace in guys.

  • X chromosome inactivation refersto the mechanism wherein one X chromosome is randomly inactivated for the duration of early embryonic improvement in lady mammals.
  • The inactivated (silenced) X chromosome is condensed right into a shape referred to as Barr body.
  • In cats, the gene encoding for the orange/ non-orange fur coloring is X-connected, thereby X inactivation explains why maximum calico cats (i.e., the ones cats which have a colour sample with orange and black spots) are lady.
  • Moreover, Rett syndrome is a neurodevelopmental disease because of a mutation withinside the X-connected MECP2 gene, and consequently this disease is a whole lot greater critical in men.
  • On the alternative hand, colour blindness is greater not unusualplace in guys due to the fact men have handiest one X chromosome.

What us Hemophilia ?

Hemophilia, that is a disease triggered due through a mutation in a single gene required for synthesizing one clotting factor, is greater not in men than in ladies due to the fact the gene accountable for this disease is placed on.e accountable for this disease is placed on.

Tus it is well explained.
