In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow ke
lara31 [8.8K]

Answer:

<h2>A) Yes, 12 mu</h2><h2>B) AaWw</h2><h2>C) 0.25%</h2><h2 />

Explanation:

As given,

Allele A for  blue anthocynin.

aa for yellow kernel;

at  second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are:  AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

a)

Recombinant progeny are  169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with  aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.

Sled dogs have a thick coat of hair that helps them withstand the cold temperatures of the arctic. Compare that adaption to a si
Svetradugi [14.3K]

Answer;

Population; physiological modifications at the individual level.

The adaptation of the sled dog best describes adaptation at the population level while the dog exposed to seasonal colder temperatures has physiological modifications at the individual level.

Explanation;

-The bodies of sled dogs are covered with two coats of hair that work together to provide a double layer of warmth. The under layer is very short and the dog sheds it in the spring to keep from overheating during warmer temperatures.

-During the colder winter months, this under layer works as an insulator against the dog's skin to keep his body warm and his core body temperature consistent. This adaptation best describes adaptation at the population level while the dog exposed to seasonal colder temperatures has physiological modifications at the individual level.
