    Hello, please please help me with this, I would greatly appreciate it!!!! THANK YOU SO MUCH!!! QUESTION 3 When first presented with a pedigree, you should initially look for general trends. For example: Are there affected individuals in each generation? Are both males and females equally affected? Are traits from a father or mother passed on to all their children? Or only to their sons or daughters? Based on these general observations, you can usually make a fairly reasonable guess...

    For each pedigree below determine the most likely mode of inheritance and label each individual with a genotype. If you know they have a dominant phenotype, but don’t know the genotype, then label them with both possibilities. Please use the alleles A and a for autosomal modes of inheritance and XA, Xa and Ya for any types of sex-linkage (note: an “a” is only on the Y if the trait is Y-linked). Modes of inheritance are autosomal dominant, autosomal recessive,...
