REMEMBER: color blindness is carried on the X chromosome only! The male has to inherit the mutated gene from his mom and her X chromosome to be color blind. Because the male has only 1 X, he has a greater chance to be color blind than a daughter who would have to inherit a bad X chromosome from each parent!
If you follow the family tree, the person 12 (the daughter of 4x5) could be either XX or XX (I'm using bold to indicate the color blind gene on the X chromosome). You cannot tell from this family tree what she is (except that we know her mom (4) is definitely a carrier!
So you need to do two potential crosses:
1. Daughter 12 is not a carrier; so she is XX
Cross XX with XY; you get the possibility of all daughters as carriers XX, or all normal sons XY.
2. Daughter 12 is a carrier; so she is XX
Cross XX with XY; you get the possibility of daughters that are color blind (XX), daughters as carriers (XX), color blind sons (XY) and normal sons.

the last time that there was an earthquake there was in 1895! that was a long time ago! it was one of the most devastating earthquakes in america! The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers (750 mi) through California.[1] It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal). The fault divides into three segments, each with different characteristics and a different degree of earthquake risk. The slip rate along the fault ranges from 20 to 35 mm (0.79 to 1.38 in 1895 as I said before!
The fault was identified in 1895 by Professor Andrew Lawson of UC Berkeley, who discovered the northern zone. It is often described as having been named after San Andreas Lake, a small body of water that was formed in a valley between the two plates. However, according to some of his reports from 1895 and 1908, Lawson actually named it after the surrounding San Andreas Valley. Following the 1906 San Francisco earthquake, Lawson concluded that the fault extended all the way into southern California.
Answer: Use Analogies You tell a story to a second person who tells it to a third person, and so on. As the story is retold, changes are introduced. Over time, the number of changes increases.
