I am very confused about how to find the critical value of the test statistic.

I have found the test statistic of 5.636, with 1% significance level and two degrees of freedom. How do I calculate the critical value?

Geneticists examined the distribution of seed coat color in cultivated amaranth grains, Amaranthus caudatus. Crossing black-seeded and pale-seeded A. caudatus populations gave the following counts of black, brown, and pale seeds in the second generation.
Seed Coat Color black brown pale
Seed Count 347 68 36

According to genetics laws, dominant epistasis should lead to  
12
16
  of all such seeds being black,  
3
16
  brown, and  
1
16
  pale. We want to test this theory at the 1% significance level.

Hello, I am studying and I am a bit confused about registers. There are segments registers, data registers, pointer registers, index registers. But I do not really understand where these are found. Are they found in 8086 architecture? For instance if I ask what type of registers are found in 8086 architecture what will be the answer? All of these or only segment registers?
