Q. In a sci-fi movie, a telekinetic man has all telekinetic daughters but sons with no telekinetic abilities. Their mother is just a regular human. What is a likely genetic basis for telekinesis in this plot?
Not enough information provided
Q. Coat color in creature X is determined by a single locus. When a true breeding black creature X and a true breeding yellow creature Y are crossed, all the resulting offspring are tan. What type of allelic relationship does this example represent?
Q. If the tan creatures Z are interbred, what are the resulting phenotypic frequencies in the next generation?
50% black and 50% yellow
33.3% black, 33.3% yellow, and 33.3% tan
25% black, 50% tan, and 25% yellow
Q. Linked genes tend to be inherited together because
they are epistatic
they are located close together on the same chromosome
they are at the same locus
they have a high penetrance
they are pleiotropic
Q. In the fruit fly Drosophila melanogaster, a mutation in the wingless gene produces flies missing wings, and the mutant allele is recessive. What is the most likely outcome of a cross between two heterozygote flies?

9 winged and 91 wingless
74 winged and 26 wingless
1 winged and 99 wingless
30 winged, 24 with intermediate wings, and 46 wingless
