Nondisjunction event during meiosis
Nondisjunction is a
process whereby sister chromatid or homologous chromosomes failed to separate
during cell division. During meiosis, Nondisjunction produce eggs or sperms
cell that don’t have the normal number of chromosome. However, there are three
forms of Nondisjunction which were:
<span> a) Failure of sister chromatids to separate during
meiosis II</span>
b) Failure of a pair of homologous
chromosome to separate in meiosis I
c) Failure of sister
chromatids to separate during mitosis.
You would associate sunny weather with the high pressure system
There would be no humidity in the low pressure system and the air motion would be very fast and the density of the pressure in the air would be high.
I do believe that it is C. crossing over :) I hope that is correct, it seems like the only plausible answer.
