If individuals 1 and 4 have a child together, the child will inherit one allele from each parent. Individual 1 has one dominant allele (D) and one recessive allele (d), while individual 4 has two recessive alleles (d). Therefore, the child will have a 50% chance of inheriting the dominant allele from individual 1 and a 50% chance of inheriting the recessive allele from individual 4. If the child inherits the dominant allele, they will not exhibit the disease. If the child inherits two recessive alleles, they will exhibit the disease. Therefore, the probability that the child will exhibit the disease is 50%.
