Question

A eukaryotic organism's genome contains 8 chromosomes. Assuming that no crossing over occurs, what is the probability (in percent) that a gamete of this organism will contain only the paternally-inherited chromosomes?

An organism with the genotype AaBbCC undergoes meiosis. What is the probability that a given gamete will have the genotype abc if the A, B, and C genes are on separate chromosomes? 0 1 1/2 = 0.5 1/4 = 0.25 1/8 = 0.125

00:01 In order to answer this question, let's talk about the inheritance in chromosomes.
00:05 In this case, as you can see, you have your three pairs of chromosomes.
00:08 It means that you have six chromosomes.
00:11 And it says, assume that crossing over doesn't occur, what is the probability that a cell will contain all of the maternal chromosomes? so let's suppose that this is the maternal chromosome, this is the paternal chromosome, the maternal, the maternal, and the maternal in the paternal.
00:24 So, they're asking you, what is the probability that agamid will contain all of the maternal chromosomes? so you have two chromosomes here and out of these two, you want this here, so you have one half chances of getting this one out of two.
00:39 And the same here out of two chromosomes you want this...
