- Sperms are normally produced in the seminiferous tubes. After production sperms are stored in the epididymis where they get to mature. During ejaculation sperms travel from the epididymis along tubes known as the vas deferens. When sperms pass by the seminal vesicle and the prostate fluids get added to the sperms. The sperms then pass by the Cowper’s gland where even more fluids are added. The semen then reaches the urethra through which it exists the human body as semen. The fluids added to the semen are very necessary because they ensure travel of the sperms. They give the sperms a medium to swim in.
- The ovarian cycle is chiefly associated with the process of the maturation of the coyote and its eventual discharge from the ovary after which it passes through the oviduct and eventually reaches the uterus. The uterine cycle involves shedding of the uterine wall and the discharge of the shedded product from the uterus. The ovarian cycle influences the uterine cycle because the wall of the uterus begins to thicken after production of the coyote.
- In males LH stimulates production of testosterone
Testosterone enables the development of male sexual organs and the development of secondary sexual characteristics.
In females LH stimulates ovulation.
FSH stimulates growth of ovarian follicles
Estrogen is responsible for development of secondary sexual characteristics in females
Progesterone initiates the female menstrual cycle.
- The placenta allows the developing embryo to take up nutrients as well as the elimination of wastes and gaseous exchange. The umbilical cord connects the embryo to the placenta.
- Dominant and recessive alleles help to determine the phenotype expression of an individual depending on whether or not the individual is homozygous. If homozygous then the recessive alleles stand out but if not then the dominant ones do souse linked inheritance works in terms of chromosome inheritance. If a person inherits two x chromosomes the person becomes female but an x Y chromosome inheritance results in a male. Both males and females can develop x linked diseases.
