In humans, short fingers (F) and a widow's peak (H) are dominant over long fingers and continuous hairline. A man and a woman, both heterozygous for the two characteristics, plan on having a child. The table below shows the possible genotypes of the offspring. ☐ Gametes FH FhfHfh FH FFHH FFHh FfHH FfHh Fh FFHh FFhh FfHh Ffhh fH FfHH FfHh ffHH Z fh FfHh Ffhh ffHh ffhh 1.6.1 State the genotype at Z.
