Is it true or false, but for a diploid organism with three pairs of chromosomes, the number of potential gametes carrying different combinations of maternal and paternal chromosomes is eight.
00:12
Okay, so how could we work this out? let's draw out our chromosomes.
00:17
So these are homologous pairs, maternal and paternal.
00:22
How could they be rearranged in gametes? well, here we see already two potential gametes, where one has all maternal and paternal.
00:32
One has all patternal.
00:34
What other ways could we have this? well, we could switch these and have two more, for a total of four, and or we could switch these as well.
00:52
Now we have six.
00:53
If we switch these, we just get back to all maternal or paternal, but if i switch these again, we now have a total of eight.
01:02
So it is true.
01:03
Is there a way that we could perhaps write this without actually having to look at them.
01:09
Yeah, there is...
