AI Thread Summary
The discussion focuses on determining the frequencies of gametes from two parents with specific genotypes, Cd/cD and cd/CD, given a recombination rate of 0.25. Participants clarify that the task involves calculating gametic frequencies rather than using Punnett squares, which are typically used for predicting offspring genotypes. The correct approach involves understanding homologous recombination and how it affects gamete formation. The gametes identified include Cc, CD, cd, dD, cC, cD, Cd, and dD. The conversation emphasizes the need to apply knowledge of recombination to derive the correct frequencies of these gametes.

Homework Statement


2 parents, one has genotypes Cd/cD and the second has cd and CD
possible gametes and if r=.25 what are frequencies of gametes


Homework Equations


punnent square


The Attempt at a Solution


So the gametes came out to be Cc, CD, cd, dD and cC, cD, Cd, and dD but I am not sure how to get the frequency

This isn't about Punnett squares. Punnett squares are for predicting the genetic makeup of progeny, when given gametic frequency.

You are given a recombination frequency and are asked to find gametic frequencies. This is about homologous recombination.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
