GUARANTEED SUCCESS
A mutation in aromatase gene in Alligator mississippiensis such that aromatase function does
not increase with temperature will result in _____________. the majority of the offspring
being males
During sex determination in Drosophila, _______ and ____________ are _______________
proteins that regulate a cascade of male or female specific gene expression. Sexlethal,
Transformer1, splicing factors
If there is a mutation that deletes the male specific exon of sexlethal, what sex would the
Drosophila offspring be? All female
Which of the following is a mammalian gene only. Sry
A conditional Cre knockout of Sox9 was made using a Sf-1cre. This caused Sox9 to be knocked
out in the bipotential gonad. What do you expect the phenotype of XY mice to be? Female
What phenotype would you expect to find if you made an SF1 homozygous null mouse mutant?
XY and XX embryos would not form a bipotential gonad.
