what happened to the urine volume when the solute gradient in the interstitial space was increased?

Answers

The urine volume decreased when the solute gradient in the interstitial

space was increased.

The solute gradient in the interstitial space being increased means more

absorption of compounds into the bloodstream and vice versa. When this

occurs, the constituent of urine decreases.

The decrease in the urine components brings about a decrease in its

volume also due to increased absorption taking place.

For each offspring genotype in the Punnett square you just completed, determine the phenotype. In other words, what is the predicted fur color and eye color of the offspring? Using your Punnett square from the last step, fill in the predicted fraction for each phenotype in the data table below.

Black Fur and Black Eyes Black Fur and Red Eyes White Fur and Black Eyes White Fur and Red Eyes
Predicted Fraction
/16
/16
/16
/16

Answers

Assuming diallelic genes, expressing complete dominance and not interacting, the predicted fractions are 4/16 Black Fur, Black Eyes - 4/16 Black Fur, Red Eyes - 4/16 White Fur, Black Eyes - 4/16 White Fur, Red Eyes

Available data:

Two traits are involved in this cross  ⇒  fur color and eye color.

Black fur color is dominant over white fur color

Black eyes is dominant over red eyes

The cross is between a h0m0zyg0us recessive parent with a dihybrid one.

What can we deduct about this information?

Assuming diallelic genes coding for each trait, expressing complete dominance, and no interaction between genes, we can propose the following genotypes and phenotypes.

         Genotype                               Phenotype          

BBEE, BbEE, BBEe, BbEe        Black fur, Black eyes

bbEE, bbEe                              White fur, Black eyes

BBee, Bbee                              Black fur, Red eyes

bbee                                         White fur, Red eyes

How to perform the cross?

Cross: h0m0zyg0us recessive parent with a dihybrid parent

Parental phenotypes)    White fur, Red eyes   x   Black fur, Black eyes

Parentals genotype)    bbee     x     BbEe

Gametes)  be, be, be, be        

                 BE, Be, bE, be

Punnett square)       BE             Be            bE           be

                     be     BbEe        Bbee         bbEe       bbee

                     be     BbEe        Bbee         bbEe       bbee

                     be     BbEe        Bbee         bbEe       bbee

                     be     BbEe        Bbee         bbEe       bbee

F1)

4/16 = 1/4 = 25% of the progeny is expected to be dihybrid, BbEe, expressing black fur and black eyes

4/16 = 1/4 = 25% of the progeny is expected to be heter0zyg0us for fur color and h0m0zyg0us recessive for eye color, expressing black fur and red eyes.

 

4/16 = 1/4 = 25% of the progeny is expected to be heter0zyg0us for eye color and h0m0zyg0us recessive for fur color, expressing white fur and black eyes.

4/16 = 1/4 = 25% of the progeny is expected to be h0m0zyg0us recessive, bbee, expressing white fur and red eyes.

Predicted fraction per phenotype

Black Fur and Black Eyes  ⇒  4/16 BbEeBlack Fur and Red Eyes  ⇒  4/16 BbeeWhite Fur and Black Eyes  ⇒  4/16 bbEeWhite Fur and Red Eyes  ⇒  4/16 bbee
