A DNA fingerprint using gel electrophoresis is able to determine what two things? I also need help with question 12 if possible

DNA fingerprinting can be used to determine a crime suspect and for paternity testing.

12.

A karyotype can be used to determine the sex of the fetus and chromosomal disorders like down syndrome.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

bacterium is not correct
