What is the probability of a gamete having at least one
maternal chromosome?

0.5 is the probability of a gamete having at least one

maternal chromosome in the metaphase plate.

Explanation:

Maternal and paternal chromosomes are randomly distributed on either side of the metaphase plate .

So for each pair there's a 50/50 chance as to which side the homologs will go on. We have 23 pairs each with 50/50 probabilities.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
