Imagine a genetic cross between two people, blood type ab. what is the probability that these people will have offspring with type b blood
a)0%
b)10%
c)25%
d)50%

the right answer is c) 25%

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
