Consider 2 genes in peas- gene controlling seed color- yellow Vs green; gene controlling seed texture-smooth Vs wrinkled. Assume

the two genes are very tightly linked. A true breeding smooth green plant is crossed to a true breeding wrinkled yellow. All the F1 progeny were smooth yellow. The F1 generations were self-fertilized. In the F2 what is the expected ratio of the phenotypes- Smooth & yellow: smooth & green: wrinkled & yellow: wrinkled & green

Answer:

Smooth & yellow: 9

smooth & green: 3

wrinkled & yellow: 3

wrinkled & green: 1

Explanation:

Gene controlling seed color are yellow Vs green

Gene controlling seed texture are smooth Vs wrinkled

In F1 generation, A true breeding smooth green plant (SSyy) is crossed to a true breeding wrinkled yellow (ssYY)

Off spring in F1 generation are smooth yellow (SsYy)

This means smooth texture is dominant over wrinkled texture and yellow color is dominant over green  

in F2 generation, the cross is carried between SsYy

SY         Sy        sY          sy

SY SSYY SSYy SsYY SsYy

Sy SSYy SSyy SsYy Ssyy

sY SsYY SsYy ssYY ssYy

sy SsYy Ssyy ssYy ssyy

Smooth & yellow: 9

smooth & green: 3

wrinkled & yellow: 3

wrinkled & green: 1

Refer to Animation: Countercurrent Multiplication. What would you predict to be the effect on an animal species of having longer
attashe74 [19]

Answer:

The correct answers is: I would predict that animals with longer loops of Henle would be able to concentrate their urine more than animals with shorter loops, and thus they would more likely survive in desserts and other dry areas.

Explanation:

The<em> Loop of Henle</em> is a tubule system that connects the proximal convoluted tubule to the distal convoluted tubule in a nephron, the functional and structural unit of the kidney. Its primary job is to establish a concentration gradient in the kidney's medulla by creating a high urea concentration deep in the medulla using a countercurrent multiplier system that uses electrolyte pumps. Through this mechanism, <u><em>water is reabsorbed to concentrate the urine and impede dehydration</em></u>.

The length of the loops of Henle is of great importance for the countercurrent multiplier system - <u>the longer they are, the more concentrated the urine can get</u>. Therefore, animals with longer loops can survive better in habitats where there is not much water around.
