Answer:
a. Determine the allele frequencies of:
- f(T) = 0.485 ≅ 0.48
-
f(t) = 0.515 ≅ 0.52
b. Determine the genotype frequencies of the exposed generation
-
F (TT) = 0.21
- F (Tt) = 0.55
- F (tt) = 0.24
the genotype frequencies of the next generation
-
F(TT) = 0.23
- F(Tt) = 0.5
- F(tt) = 0.27

The answer is actually 4.4 billion years, but i guess you can estimate to 4.5
Answer:
Option C
Explanation:
All of the following options are correct except option C. in the Meselson Stahl experiment, after the first round of replication, the DNA molecules made consisted mainly of one parental strand and one new strand each which is the DNA molecules of intermediate density (H-L). Then future replications will produce more of the low density L-L density. This form of replication is thus termed to be the semi conservative form of replication
