The trait represented by the colored circles and squares below is inherited as a dominant allele. This is not a sex-linked trait. Shaded individuals show the dominant trait.

The trait represented by the colored circles and squares below is inherited as a dominant allele. This is not a sex-linked trait. Shaded individuals show the dominant trait. What is the probably genotype of each individual? Are there any homozygous dominant individuals in the pedigree above? How do you know? What is the probability of the trait appearing in offspring if 7 should marry 9? What is the probability of the trait appearing in offspring if 8 should marry 10?

The accompanying figure is a pedigree of a fairly common human hereditary trait in which the boxes represent males and the circles represent females. Shading symbolizes the abnormal phenotype. Given that one gene pair is involved: a) Is the inheritance pattern X-linked or autosomal, recessive or dominant? b) If the two individuals marked with an asterisk (*) had a child, what is the probability that he/she would be affected? *List answers as an unsimplified/non-reduced fraction!

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. a. Autosomal recessive trait b. Autosomal dominant trait c. X-linked recessive trait d. X-linked dominant trait e. Y-linked trait
