Assertion :Mendelian disorders may be dominant or recessive.
Reason : By pedigree analysis it can be easily interpreted that trait is dominant or recessive. a. If both assertion and reasons are true and the reason is the correct explanation of the assertion. b. If both assertion and reason are true but reason is not the correct explanation of the assertion. c. If assertion is true but reason is false. d. If both assertion and reason are false.

Sure, here are the step by step solutions: 1. Determine the inheritance pattern of the trait - whether it is dominant or recessive. 2. Analyze the pedigree by observing the pattern of inheritance of the trait across generations. 3. If the trait is dominant, it will be present in every generation of the pedigree and will be seen in both heterozygous and homozygous individuals. 4. If the trait is recessive, it may skip generations and will only be present in individuals who are homozygous for the trait. 5. Look for clues in the pedigree such as consanguinity (related parents), affected siblings, and affected parents to help determine the inheritance pattern. 6. Use Punnett squares to help predict the likelihood of the trait being passed on to offspring. 7. Repeat the analysis with multiple pedigrees to confirm the inheritance pattern. 8. Once the inheritance pattern is determined, use this information to help diagnose and treat individuals affected by the disorder.
