I believe the answer for the above question is Gene pools. Gene pools are the total number of genes of every individual in an interbreeding population; contains variations in genes, the relative gene frequencies, and also the allele frequencies. Relative frequency being the average number of occurrences of a particular event in a large number of repeated units while the allele frequency of an allele compared to other alleles of the same gene in population.
Prostatic acid phosphatase was purified from prostatic fluid. Monospecific antisera to the purified acid phosphatase was then produced in rabbits. When antibody was coupled with acid phosphatase, the enzymatic activity was markedly stabilized against pH and temperature degradation. Both acid phosphatase and rabbit anti acid phosphatase were non specifically coupled to Sepharose-4B using cyanogen bromide. Under these circumstances slight stability occurred when antibody was bound to Sepharose, and then acid phosphatase added to the gel antibody complex. When acid phosphatase was complexed to Sepharose, no stabilization occurred.
Answer:
The most important hormone involved in controlling sperm production is a steroid called testosterone. This is produced in the testis itself, by the Leydig cells (see Figure 12a). The testosterone is released from the Leydig cells between the tubules, and taken up by the neighbouring Sertoli cells.
I think it's fight or flight
