1. Glucogenic amino acids- which are degraded to pyruvate, α-ketoglutarate, succinyl-CoA, fumarate, or oxaloacetate and are therefore glucose precursors

2. Ketogenic amino acids- which are broken down to acetyl-CoA or acetoacetate and can thus be converted to fatty acids or ketone bodies

BAFF-R expression is first detected in T1 B cells and increases steadily there after.

Signaling through the BAFF/BAFF-R axis promotes survival of transitional B cells by inducing the synthesis of anti-apoptotic factors such as Bcl-2, Bcl-xl, and Mcl-1

Genetic drift 

Genetic drift is an evolutionary force, in which allelic frequency change over generation Just by chance (sampling error). 

The deviations from the expected ratios are random, the direction of change is unpredictable.
