Using Punnett squares, calculate for each of the scenarios below, the risk each couple has to have the affected, carrier, and normal offspring. Assume that the disease is cystic fibrosis (6 points):

Carrier mother, Normal father;

  1. ? Risk of: __% AFFECTED daughter; __ % AFFECTED son; __ % CARRIER daughter; __ % CARRIER son; __ % NORMAL daughter; __ % NORMAL son

Normal mother, Affected father;

  1. ? Risk of: __% AFFECTED daughter; __ % AFFECTED son; __ % CARRIER daughter; __ % CARRIER son; __ % NORMAL daughter; __ % NORMAL son

Carrier mother, Affected father;

  1. ? Risk of: __% AFFECTED daughter; __ % AFFECTED son; __ % CARRIER daughter; __ % CARRIER son; __ % NORMAL daughter; __ % NORMAL son

Sex-linked crosses 4. Hemophilia is an X-linked disease, meaning that the gene that causes the disease is found on the X chromosome. Affected males only have to have one allele to have the disease (XhY), while affected females have to have two alleles (XhXh). Imagine that an affected male has children with an unaffected carrier female. a. What are the genotypes of the parents in this cross? b. Draw a Punnett cross to show the offspring of this couple. c....
