1.	Human, mice and fly males are _______ for loci on the X chromosome. -> Homozygous True False
2.	A mutant phenotype refers to -> an abnormal, degenerative phenotype True False
3.	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? -> Mitochondrial True False
4.	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? -> Genetic linkage True False
5.	If the tan creatures Z are interbred, what are the resulting phenotypic frequencies in the next generation? -> 25% black, 50% tan, and 25% yellow True False
6.	Linked genes tend to be inherited together because -> they are located close together on the same chromosome True False
7.	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? -> 46 winged and 54 wingless True False
8.	Continuous traits -> are option 1 and 3 True False
9.	A floriculturist is interested in generating roses with larger petals. He measures the following components for petal radius in a population of plants from his farm. Additive genetic variance (V_A): 5.1 Dominance genetic variance (V_D): 1.1 Interaction genetic variance (V_I): 0.5 Environmental variance (V_E): 3.0 Genetic-environmental variance (V_GE): 0.1 What is the phenotypic variance? -> 0 True False
10.	What is the broad sense heritability? -> 1.0 True False
11.	What is the narrow sense heritability? -> 5.1 True False
