Hello everyone here we have a question that says Huntington's disease is a progressive autism. A dominant brain. This word that affects cognition, emotion and movement but only after a certain stage in the process of the genes mutation a hetero zaius man with Huntington's disease is made to a normal woman. And our goal here is to determine the likelihood that their future Children will have Huntington's disease. So it's important to note that it is autism all dominant and the man is hetero Zaha's and the woman is normal. So the man we will call capital a lowercase A. Because it is autism more dominant. And the normal woman we will call lowercase a lowercase A. So we will have capital A lowercase A. That will be an affected child. Lowercase a lowercase A. That will be a normal child capital A lowercase A. That will be an affected child. Lowercase a lowercase A. That will be a normal child. So our answer here is c half of their Children will be affected by Huntington's disease. Thank you for watching. Bye.
