Solutions For An Introduction to Genetic Analysis Chapter 9 Problem 42P

Step-by-Step Solution

Solution 1

The anemia is a condition in which the red blood cell count is very low. Consequently, the oxygen carrying capacity of the hemoglobin is reduced. It is a genetic disorder.

The events that would takes place in a sequence are arranged as follows:

f, d, j, e, c, i, b, h, a, g.

The sequence is as follows:

f. A mother (an X-ray technician) accidentally steps in front of an operating X-ray generator.

d. The ovum (female gamete) receives a high radiation dose.

j. Nucleotide-pair substitution occurs in the DNA of the gene for hemoglobin.

e. An incorrect codon is generated in the DNA of the hemoglobin gene.

c. An incorrect codon is transcribed into hemoglobin mRNA.

i. The tRNA anticodon that lines up is one of a type that brings an unsuitable amino acid.

b. The shape of the oxygen-binding site is altered.

h. The oxygen-transport capacity of the body is severely impaired.

a. Anemia is observed.

g. A child dies.
