Genetics | X-chromosome Inactivation, Barr Bodies, and the Calico Cat

The video explores sex chromosomes, focusing on X chromosome inactivation and its role in gene expression. It explains the formation of Barr bodies and how this process affects different genotypes, including Klinefelter and Turner syndromes. The video also discusses the unique coloration of calico cats, which results from random X chromosome inactivation, and touches on the genetic basis for their patterns.

Discuss the genetic basis for the color patterns observed in calico cats.

Why are calico cats predominantly female, and what is the exception?

How does random X chromosome inactivation contribute to the appearance of calico cats?

What role does the autosome play in the coloration of calico cats?
