You discover a new alien race that you decide to call the PAMMARIANS. They are different from us in that they have three sexes, called Q, R, and S. All three sexes must fuse their gametes to form a new PAMMARIAN (and you thought dating on the Earth was hardi). They have nuclear DNA and extrachromosomal organelles, similar to mitochondria, called MITOCHLORIANS, which have their own DNA. The R gender is like human females (they donate the cytoplasm during the mating). Q and S do NOT donate cytoplasm during mating, like human males. Which of the following is TRUE? A. In a mating, if only the Q gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring WILL HAVE a mitochlorian mutant phenotype.
B. In a mating, if the S and a genders have a mitochlorian DNA mutation, the offspring will be mutant as well.
C. In a mating, if only the R gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring will have NO mitochlorian mutant phenotype.
D. In a mating, if only the gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring WILL HAVE a mitochlorian mutant phenotype.
E. In a mating, if only the Q gender individual has a mitochlorian DNA mutation that causes a phenotype, the offspring will have NO mitochlorian mutant phenotype.
