Tall = TT or Tt; Short = tt
Pink body = PP or Pp; Yellow body = pp
For the trait of head height, where tall (T) is dominant to short (t), Patrick could have the genotype TT or Tt for a tall head, and tt for a short head. The presence of at least one dominant allele (T) results in the tall phenotype.
Similarly, for body color, where pink (P) is dominant to yellow (p), Patrick could have the genotype PP or Pp for a pink body, and pp for a yellow body. Again, the presence of at least one dominant allele (P) leads to the expression of the dominant phenotype.
Genotypes are representations of an individual's genetic makeup, with each gene having two alleles, one inherited from each parent. In this context, Patrick's possible genotypes for head height and body color are determined by the dominance relationships of the alleles involved in these traits.
