A child of normal growth can be born to dwarf parents only if his parents are heterozygous for this trait. Consequently, the gene for dwarfism dominates the gene for normal growth, and the genotypes of the parents are Aa. According to the law of splitting, the probability of the next child of normal height is 1/4, and the next two – 1/16.
