laxboi33 Posted October 1, 2009 Posted October 1, 2009 I'm just learning mitosis for the first time so bare with me here. I understand that during interphase the chromosomes are difficult to see. Also they duplicate during S-phase. 1)Are they chromatin at this point or still chromosomes? 2)How are the male and female traits divided at this point? If they are chromatin how are they divided? If they are chromosomes how are they divided?
Mokele Posted October 1, 2009 Posted October 1, 2009 1) Chromatin. 2) I'm not such what you mean by male and female traits being divided.
Capita Posted October 1, 2009 Posted October 1, 2009 The male and female traits would already be predetermined by the sperm upon the creation of the zygote. If the sperm is adding a X chromosome thus XX then it is a female vice versa XY male.
laxboi33 Posted October 2, 2009 Author Posted October 2, 2009 ok, one more question. During Interphase, are the chromosomes considered chromatin at this point or are they just considered really thin chromosomes.
Mr Skeptic Posted October 2, 2009 Posted October 2, 2009 Incidentally, the DNA of eukaryotes is always in chromatin form. When they form the tight bundles that you can see as individual chromosomes it's called heterochromatin, and when it is in its normal, dispersed form it is called euchromatin.
