For a human male, what is the probability that all the maternal chromosomes will end up in the same gamete?

Oops! I ought to have thought a bit more before posting that question. Thank you. :)

Homework Statement A ray of light incident on a glass sphere (refractive index sqrt 3) suffers total internal reflection before emerging out exactly parallel to the incident ray. What was the angle of incidence? μ = refractive index of the glass sphere, i = angle of incidence, r = angle...

Thank you. :approve:

I know the answer to the question and how to answer it, but I don't have an intuitive explanation as to why I answered it like the way I did. I still don't know why E2 is added to and subtracted from E1 in the first case and second case respectively. Also, is there any other way to come up with...

I did that at first; but ended up opening the file in another tab, copying its URL, inserting it in that post, and deleting the attachment. :redface: My apologies.

Thanks for the reply. Yes, it can be viewed as a homework problem (though answering the question isn't exactly part of my homework). I have roughly drawn the following circuit diagrams in reference to the question...

I don't have a clear perception of how the following question is answered: "Two primary cells of emfs E1 and E2 respectively are joined in series with (i) the same polarity, and (ii) opposite polarities. The combination is connected through a galvanometer and a jockey to a potentiometer. The...
