Beta thalassemia is a disease that causes low levels of hemoglobin. To inherit this autosomal disease, an
individual must receive two mutant alleles. Which of the following likely represents the chromosome
pairs of a healthy parent who has a child with beta thalassemia? (The yellow band represents the
mutant allele and the green band represents the normal allele.) * Correct Answer-Option 3- The
chromosomes of a healthy parent who has a child with beta thalassemia must be a carrier of the
disease, i.e. the parent must have one copy of the (dominant) normal allele and one copy of the
(recessive) mutant allele.
Your black dog and your friend's white dog have puppies. If inheritance of coat color is co-dominant, the
coat color of the puppies will be ________________, the color will be _______________ if incompletely

Freidreich's ataxia is an autosomal recessive disorder that results from multiple GAA insertions into the
FXN gene. Which of the following best illustrates the inheritance pattern of Freidreich's ataxia in a family
with the disease? Correct Answer-None of these pedigrees are consistent with an autosomal recessive
pattern.
The pedigree chart for Option 3 shows evidence of carriers, and both males and females have Friedrich's
ataxia in this chart. These properties of the chart indicate that it is for an autosomal recessive disease. [Show Less]
