Step 8
One week later Moko returns to your office. You have not sent her the results yet, but she is leaning towards choosing for Bohapy already. Because of that she asks you to perform two to three extra calculations.
Moko lives far away from the equator of Zork, close to the south pole. Even though the climate is okay for most of the year, during winter it gets bitterly cold.
The subspecies of Zokkies that evolved at the southern hemisphere around the polar zones has adapted in several ways to their environment. Some are able to form thick layers of blubber in wintertime, a trait coded for by allele IB. Allele IN codes for a regular thickness of skin fat. Intermediate phenotypes are known to be prevalent in temperate climates.
Another adaptation is the ability to boost the production of metabolic hormone or MH during winter, allowing Zokkies to consume more lipids and immediately transform the energy content into heat. This adaptation is enabled for carriers of the Xm+ allele. Normal metabolic activity is coded for by XM.
Mokos family has roots in the south, but some family members came from equatorial Zork. Moko is heterozygous for her blubber layer and slightly blubbery, homozygous for the MH production.
Bohapy comes from the north. He cannot produce any blubber, but an ancestor left him with the ability to produce more MH.
Petei is unable to produce additional MH. He does carry a thick blubber layer.
Moko asks to know how many of their offspring would be able to survive in the deep south, where she is planning to settle after all of this. For this, they should phenotypically show both adaptations.
Use the form in source 2 to perform the two dihybrid crosses. Use a clutch size of 120 eggs for your calculations.
After a week, you send the results of your calculations to Moko.
