C27. A sex-influenced trait in humans affects the length of the index finger. A short allele is dominant in males and recessive in females. Heterozygous males have an index finger that is significantly shorter than the ring finger. In contrast, the long allele is dominant in females and recessive in males. The gene affecting index finger length is located on an autosome. A female with short fingers has five children with a male who has long index fingers. The order of birth is: female, male, male, female, male. The oldest female offspring and a male with long index fingers have one male offspring. Draw the pedigree for this family. Indicate the phenotypes of every individual (filled symbols for individuals with short index fingers and open symbols for individuals with long index fingers.
