Family members with eye cataract are shown with a solid left

Family members with eye cataract are shown with a solid left half of the symbol; those with pituitary dwarfism are indicated by a solid right half. What is the most likely mode of inheritance of each of these phenotypes? Eye cataracts (autosomal recessive) and dwarfism (autosomal recessive) Eye cataracts (autosomal dominant) and dwarfism (autosomal dominant) Eye cataracts (autosomal recessive) and dwarfism (autosomal dominant) Eye cataracts (autosomal dominant) and dwarfism (autosomal recessive)

Solution

b. Eye cataracts (autosomal dominant) and dwarfism (autosomal dominant)

Affected persons has atleast one affected parent and it leads to 50% chance of being affected. In autosomal dominant, the disease appears in every generation, whereas in autosomal recessive the disease does not appear in every generation.
