Early in mitosis, during prophase and prometaphase, the nucleus, nucleolus and nuclear envelope begin to dissolve in preparation for cell division. During telophase, which is the final stage in mitosis,, there is a reversal of effects of prophase and prometaphase; nucleus, nucleolus and nuclear envelope are again formed.

Please help! c:

I think I understand even without the picture. I'll add a picture of the Punnett Square filled in, but what you're crossing is

Tt x tt (heterozygous crossed with a homozygous recessive)

The ratio you get in the end is 2 heterozygous (Tt) and 2 homozygous (tt) offspring, so the ratio is 1:1.

So the percentage of offspring that are homozygous recessive is 50%.
