Answer:
Perfectly in theory, except there is chance involved
Explanation:
The Punnet square is a diagram that allows scientists to predict the possible outcomes of the offspring when the genotypes of the parents are known. This is in line with Mendel's principles, and from a theoretical point of view would match up perfectly. However, it all works based on <em>probability</em>.
However, inheritance is always down to chance. Of your parents 2 alleles, you always have 50:50 chance of inheriting one of the allele. Overall, this is what is predicted in punnet squares.
However, think about flipping a coin. There is always 50:50 chance of getting heads, but that doesn't mean it is impossible to flip a coin and get tails 10 x in a row. It is just less likely. So in reality, observations might deviate from the theory.
Answer:
Null hypothesis: male and female spiders organized in mating pairs don't differ significantly in respect to body length
Alternative hypothesis: male and female spiders organized in mating pairs exhibit significant differences in respect to body length
The application of one statistical test in order to obtain one p-value (probability value) may provide useful evidence to support the alternative hypothesis (or reject it).
The inference procedure uses the information collected from the sample in order to obtain one conclusion. Frequentism is a type of inference procedure that can be used to test a hypothetical test case, which is here represented by male and female spiders organized in mating pairs.
