Epinephrine is popularly known as adrenaline. It is a water-soluble natural hormone that is secreted by the adrenal glands in the brain (Rushton, 2009). Acute stress triggers the release of epinephrine into the bloodstream. In return, the heart rate, blood pressure, sugar metabolism, and heart rates spike allowing a person to react quickly (George, 2020).

Abstract The determination of sex for several species has been genetic with females and males bearing different genes/alleles specifying their sexual morphology. Sex determination in animals in most cases goes hand in hand with differences in chromosomes through haplodiploidy or chromosomal combination of ZW, ZO, XY, and XO. This difference is often accelerated by a
