The red kernel color in wheat is caused by the presence of at least one dominant allelefrom each of two independently segregatin

g gene pairs (e.g.,R-B-). Wheat plants withrrbbgenotypes have white kernels, and plants with genotypesR-bbandrrB-have yellowkernels. You cross a plant true breeding for red kernels with a plant true breeding forwhite kernels.a. What is the expected phenotype(s) and ratios of the F1plants?

Answer:

100% red kernel color

Explanation:

R_B_ = Red kernel color

R_bb and rrB_ = yellow kernel color

rrbb = white kernel color

True breeding red kernel x true breeding white kernel = RRBB x rrbb

F1 genotype ratio = 100% RrBb

F1 phenotype ratio = 100% red kernel color plant.

<em>The expected phenotype of the F1 plant is 100% red kernel color.</em>

What kind of exercise should you do during a warm-up?
vitfil [10]
<span>If jogging you should start off with a brisk walk and transition after about 1 minute to a slow jog. Then pick up your pace as your legs become warm with increased blood flow. If biking you should do a few static calf and thigh stretches but don't extend too far as muscles are cold. Then start off your cycling at a very slow comfortable pace. After about a minute you can start to slowly increase your pace until you reach your goal.</span>

Andrew is lactose intolerant. what happens to water movement in the presence of the double sugar, lactose, which remains in the
Juli2301 [7.4K]
When someone is lactose intolerant, it means its intestine cannot absorb lactose, which will stay in the lumen and be consumed by intestinal bacteria and produced gases, that's why intolerant lactose people have flatulence and abdominal pain while eating food with lactose in it.
Let's go back to the question, before being consumed, lactose in the lumen intestine will attract water from the enterocytes to its side by oncotic pressure.

Do not confound oncotic pressure (which concerns macromolecules like sugar or proteins) and osmotic pressure (which concern micromolecules like small ions (sodium potassium and chloride...)).
