Answer:
The three anatomical structures that, in order, contribute to the production of mature sperm are the epididymis, seminal vesicle and prostate.
Explanation:
The sperm and the first seminal fluid are produced and found initially in the seminiferous tubules of each testicle. From there they move on to several structures that contribute to the maturation process:
- Each <u>seminiferous tubule </u>drives the sperm to the epididymis, through the vas deferens, where the sperm can be for a long time and complete their maturation process.
- From the epididymis, the sperm pass to the seminal vesicle, which produces more seminal fluid to give nutrients to the sperm and facilitate its movement.
- Finally, and before being expelled outside, the seminal fluid receives the prostatic secretion in the prostatic urethra, a viscous and whitish liquid that completes the seminal fluid content.
The process of maturation of sperm is of importance for the process of sexual reproduction.

Explanation:
Answer:
The chance of having a Child who is a Heterozygote is 50% , The chance of having a child that will completely come down with Alpers syndrome is 0%
Explanation:
Jack has a history of Alpers in his family
Jill has no history
lets assume Jack is a carrier : Ab ( because that is how he could have survived the first 10 lethal years )
Jill : AA
Therefore the probability/chance of Jack and Jill having a child with Alpers ( carrier ) syndrome will be 50 % as shown below
AA * Ab = AA , Ab, AA, Ab
The child produced by Jack and Jill will only be a carrier of the syndrome and not completely affected by the syndrome
