5. A man with a specific unusual genetic trait marries an unaffected woman and they have four children. Pedigrees of this family are shown in parts (a) through (e), but the presence or absence of the trait in the children is not indicated. For each type of inheritance, indicate how many children of each sex are expected to express the trait by filling in the appropriate circles and squares. Assume that the trait is rare and fully penetrant. If the trait is an autosomal recessive trait If the trait is an autosomal dominant trait If the trait is an X-linked recessive trait If it is a Y linked trait

1. Please consider the following pedigree. I 1 2 II 1 a) Assume that colour is controlled by a single sex-influenced gene where orange is expressed preferentially in females. Individuals I-1 and I-2 are homozygous for orange and blue respectively. Which individual/s in generation II will be blue? b) If colour is a controlled by cytoplasmic DNA, which individual/s in generation II will be orange?
9. We will determine if the pedigree below can be for a trait that is autosomal dominant. Use "A" and "a" where A represents the dominant allele and "a" is the recessive allele. Darken symbol means the individual exhibits the dominant trait.e a) Write the genotype of each individual next to the symbol.e b) Is it possible that this pedigree is for an autosomal dominant trait?e
