Two parents think their baby was switched at the hospital. Its 1982, so DNA fingerprinting technology does not exist yet. The mother has blood type "O," the father has blood type "AB," and the baby has blood type "B."

a. Mother’s genotype:

b. Father’s genotype:

c. Baby’s genotype: or

d. Punnett square showing all possible genotypes for children produced by this couple.

e. Was the baby switched?

According to the rna world hypothesis, rna acted as the genetic material and catalyzed reactions in ancient cells. what conclusion can you draw from this?               a.  this implies that dna and proteins aren't essential in cells today.    b.  this implies that rna can catalyze any chemical reaction that enzymes catalyze.    c.  this implies that if a cell has a problem with its dna, its rna can compensate for the damaged dna.    d.  this implies that dna and proteins evolved after rna.
