When you finger gets pruning because they were in water to long
Answer: P(p and f) = 0.23
Explanation: The frequency of a specific trait is also the probability of that trait appearing in that population. So:
Probability of purple pollen cones: P(p) = 0.34
Probability of four needles per fascicle: P(f) = 0.67
Using multiplication rule:
P(p and f) = P(p)*P(f)
P(p and f) = 0.34*0.67
P(p and f) = 0.23
The probability of having both purple and four needles is 0.23
Well I assume you are talking about a human being. Stem cells can turn to any kind of cell the body needs. Babies have the most stem cells because their bodies are still being formed. In an adult there is little to no stem cells found for they have fully developed. But if your question is based on the life cycle of a cell, there are many different types of cells with different beginnings or bases.
