What is on the worksheet

1. In a canonical double-stranded DNA sample, adenine is 34% of all bases. Find the guanine percentage, assuming A = T and C = G. Round to 3 decimal places if needed. Answer in %.

2. In the simple Aa × Aa inheritance model with independent outcomes, the probability of aa is 1/4. Among 316 offspring, find the expected aa count, not a guaranteed outcome. Round to 3 decimal places if needed.

3. In the simple Aa × Aa inheritance model with independent outcomes, the probability of aa is 1/4. Among 152 offspring, find the expected aa count, not a guaranteed outcome. Round to 3 decimal places if needed.
