Step 8
One week later Sin returns to your office. You have not sent her the results yet, but she is leaning towards choosing for Yan already. Because of that she asks you to perform two to three extra calculations.
Sin lives on a large plain where you can find the local subspecies of field bugs, parasitic organisms that live from blood..
She and Yan have both been tested for the presence of alleles for thick (t) and medium to thin (T) skin and for the presence of the allele that enables a Zokky to produce an alkalic compound as part of their sweat (S). Both turn out to be heterozygous for both characteristics. Secunda would like to know what ratio to expect in their possible offspring : How many children would be able to make it hard for the bugs to get through their skin, how many should be able to deter the bugs with alkalic sweat and how many should be able to do both (and thus be able to safely live on the plain without additional precautions)?
Use the form in source 2 to perform a dihybrid cross. Use a clutch size of 140 eggs for your calculations.
After a week, you send the results of your calculations to Sin.
