Answer is Independent assortment.

Fraternal twins each come from their own egg and sperm. Hence, these are dizygotic. Just like any brothers and sisters, fraternal twins will share about 50  %  of their DNA. Each person receives half of their DNA from mother's egg and the other half from father's sperm. Fraternal twins may or may not share similar characteristics due to Independent assortment of genes occurs during meiosis. In meiosis the number of chromosomes in a parent cell is reduced by half to produce four reproductive cells or gametes. During meiosis, the pairs of homologous chromosome are divided in half to form haploid cells. The assortment or separation of homologous chromosomes are random.

torisob [31]

In which sections or section of the kidney is the urine formed? 

The final product of filtration, reabsorption, and secretion which is the urine is primarily formed in the renal medulla although the formation of the urine starts with the filtration of blood in the glomerulus then along the proximal tubules, descending and ascending loop of Henle, distal tubules, and collecting ducts. 


What section of the kidney collects the urine? 

The renal pelvis is the main section of the kidney that collects the urine. The renal pelvis arises from the confluence of the collecting ducts forming the renal papilla then the minor calyx and the major calyx and ultimately to the renal pelvis to be transported to the urinary bladder through the ureters.


How does the urine move from the kidney out of the body? 

The urine will be collected in the renal pelvis. With the urine collected in the renal pelvis, the urine moves from the renal pelvis to the urinary bladder through the ureters and will be stored in the urinary bladder. When there is an urge to urinate, the urinary bladder contracts and the urethral sphincter relaxes that allows passage of the urine from the bladder out of the body through the urethra.


In which main regions of the kidney are the glomerulus and the Bowman's capsule located? 

The glomerulus and the Bowman’s capsule are part of the renal cortex. These organs are responsible for the filtration of the blood from the afferent arteriole. The glomerulus and the Bowman’s capsule are not synonymous but rather the glomerulus comes from the afferent arteriole and the Bowman’s capsule functions as a filtration membrane. Together, they are called the renal corpuscle.


In which main regions of the kidney are the collecting ducts and the loop of Henle located?

The collecting ducts are located in the renal medulla whereas the loop of Henle are partly in the medulla, depending on the type of nephron. In superficial cortical nephrons, the dips only up to the outer medulla while in the juxtamedullary nephrons, the glomerulus is near the corticomedullary border wherein more parts of the loop of Henle is in the medulla.
