Sexual Selection in Crawfish
Storyboard Text
- I'm starting to finally understand! Therefore we can conclude that there is variation for sexual selection to act upon and that sexual dimorphism for claw size is seen in crayfish!
- Exactly, so females are likelier to mate with bigger-clawed males. Additionally, sexual selection continues to occur because there will always be variation in a natural population for it to act upon!
- Wow! Sounds cool! How will we assess this?
- 3. Fill out the class spreadsheet with your data, then watch your TA plot the frequency histogram of the raw data in RStudio.The figures will demonstrate sexual dimorphism and the distribution of male claw sizes!
- 1. Measure the greatest length of the propodite of three crayfish with a caliper .2. After figuring out each crayfish's sex, return them to their original container.
- And what about in the second plot?
- In Figure 2, we can observe that the population of crayfish did show sexual dimorphism as as the p-value of 1.85e-15 states there is a significant difference between the claw lengths of the females and the males.
