**Question 14:**Study the pedigree examining Huntington's Disease in a family. According to the pedigree below, what is the chance that individual A will be afflicted with Huntington's (a dominant disease)?**Diagram Description:**- The pedigree chart shows two generations.- Affected individuals are marked with filled black circles or squares, representing males and females, respectively.- Unaffected individuals are marked with open circles or squares.**Key Details:**1. The first generation consists of one affected female and one unaffected male.2. They have three children: one affected female, one affected male, and one unaffected female.3. The affected male from the second generation is labeled as "Individual A."**Question Options:**- 75%- 100%- 25%- 50% **Pedigree Analysis:**Huntington's Disease is an autosomal dominant disorder, meaning an affected individual has a 50% chance of passing the affected allele to each offspring. Individual A may inherit the affected allele from his affected parent.

Huntington's disease is an autosomal dominant disorder. Therefore, Possible genotypes of affected persons - AA or Aa And, genotype of unaffected persons - aaFrom the pedigree, The father is affected (AA or Aa) but the mother is not (aa). Since two of their children are not affected, the genotype of the father is confirmed to be - Aa. CROSS: Parents: Aa x aa Offspring: A a a Aa (affected) aa (not affected) a Aa (affected) aa (not affected) The probability of a child born tho the parents being affected is 2/4 = 1/2 or 50%. Therefore, the chance that individual A will be affected with Huntington's disease is 50%. The last option is the correct answer. All the options are not correct because from the cross, the chance of a son or daughter being affected is 50%.
