After mutation by PX-41, minions exhibit several new traits, such as purple skin instead of yellow, and being indestructible (as opposed to not indestructible). You notice that purple skin (P) is dominant to yellow skin and being indestructible is recessive to destructible (D). As these phenotypes are the result of a mutagen you hypothesize that the genes for skin color and destructible-ness are very close to each other on one chromosome, and therefore linked. In order to test this hypothesis, you first cross a true-breeding purple indestructible minion with a true-breeding yellow destructible minion in order to generate a female minion heterozygous for both traits which you perform a test cross with. You observe the offspring and see following results:





Purple and Indestructible : 137



Purple and Destructible: 111



Yellow and Indestructible: 109



Yellow and Destructible: 143



Which of the following phenotypes represent recombinant gametes in the mother? (check all that apply)


Purple and Indestructible


Purple and Destructible


Yellow and Indestructible


Yellow and Destructible

Using the information above, what is the recombination frequency between the "P" gene and the "D" gene?

Does this mean that the "P" gene and the "D" gene are likely linked or likely independently assorting?
