In humans , the allele for brachydactyly ( abnormally short fingers ) is dominant . The normal finger condition is the recessive trait . Both parents are heterozygous . Use the letter " B " for the brachydactyly allele and letter " b " for the normal allele . 1. What is the genotype of the father ? 2. What is the phenotype of the father ? 3. What is the genotype of the mother ? 4. What is the phenotype of the mother ? 5. What is the predicted genotypic ratio in the offspring of these two people ? 6. What is the predicted phenotypic ratio in the offspring of these two people ? 7. What is the chance ( as a percentage ) that their children will be heterozygous like their parents ? 8. What is the chance ( as a percentage ) that their children will have brachydactyly like their parents ? Perm Reply
