The correct answer is B. A hypothesis can be proven incorrect through experimentation

Explanation:

In science, a hypothesis refers to a prediction or educated guess about a certain phenomenon. This is part of the scientific method that aims at explaining phenomena in the world. Moreover, hypotheses are only validated through experimentation; indeed, scientists carry out different experiments following certain standards and then they can conclude a hypothesis is correct or incorrect.

On the other hand, a hypothesis differs from a theory or law because these are proven explanations or rules about a natural phenomenon that can be disproven through new evidence or experiments. According to this "a hypothesis can be proven incorrect through experimentation" is the true statement.

The genealogy tree which is missing from the question is in the attachment.

Answer: 1) P1 = $\frac{1}{2}$ ; 2) P2 = $\frac{1}{2}$ ; 3)P3 = $\frac{1}{16}$

Explanation: 1) According to the genealogy tree, the individual III-3 has a P1 = 1/2, because each of the parents are heterozygous for the condition, since one of the ofspring is affected.

2) For individual III-4, one of the parents is heterozygous for the condition, so the probability of being a carrier is P2 = 1/2.

3) Now, for individual IV-1 be affected, the parents has to be carrier. So, this probability, depends on the probability of each parent being heterozygous and that the individual will be carrying the condition, which means:

P3 = 1/2 · 1/2 · 1/4 = 1/16.

The probability of having the condition is 1/16 or 6.25%.
