Explanation:
The expected phenotype ratio is 9:3:3:1 for a BbFf x BbFf cross.
Explanation:
Data given:
Black fur dominant = BB, short fur dominant FF
brown fur recessive = bb, long fur ff
genotype of parents:
BbFf and BbFf
The cross between these two genotype of parents is shown in the below punnet square:
BF Bf bF bf
BF BBFF BBFf BbFF BbFf
Bf BBFf BBff BbFf Bbff
bF BbFF BbFf bbFF bbFf
bf BbFf Bbff bbFf bbff
phenotype ratio:
black fur and short guinea pig = 9
black and long fur = 3
brown and long fur = 3
brown and short fur-1
The expected phenotypic ratio is 9:3:3:1
Answer:
<em>Nephrostomy</em>
Explanation:
<em>Nephrostomy is a surgical procedure usually performed when there is difficulty for produced urine to leave the kidney and find its way to the urinary bladder. The difficulty happens as a result of blockage around the kidney.</em>
When blockage happens and urine cannot leave the kidney, it results to a damage to the kidney. Hence, those experiencing kidney blockage which could be as a result of kidney stone or ovarian cancer usually undergo nephrostomy.
During nephrostomy, a small incision is made on the patient's skin and the nephrostomy tube or catheter is passed through the skin into the urinary tract. The other end of the tube is connected to a urinary bag.
