In mice, a male and female are mated, both with long ears. All female have long ears but half the males bave short ears and half

rjkz [21]

If you have both parents with long ears and some of the offsprings have short ears, you can say both parents are heterozygous for this. Both have a dominant (long ear), and a recessive allele (short ear).

To prove this, you can draw a Punnett square, and you'll see the probabilities of the offsprings.

Cattle on an open range, in some areas, may compact fragile soils while grazing. This can damage plant roots, leading to fewer,

sp2606 [1]

Answer:

The given situation is an example of the Positive feedback loop.

Explanation:

Positive feedback is the phenomenon in which the effects of the small disturbances on a particular system can result in an increase in the perturbation magnitude. Positive feedback increases the input and causes instability in the system. Therefore, it refers to positive loop gain about closed loop of the cause and effect.

Therefore, the given situation is an example of the Positive feedback loop.

The purple spots on colorless background of corn kernels observed by barbara mcclintock were the result of _______.

vitfil [10]

The purple spots on the colorless background of corn kernels observed by Barbara McClintock were the result of the transposition of the Ds elements out of the color gene.

<h3>What are the genetic elements found in corn?</h3>

A transposable element is removed from one spot in the DNA and inserted into a different site in the DNA during the process of genetic transposition, which allows genes to shift their location on chromosomes.
The first recognized genetic instability was caused by genetic transposition.
The size of the tissue patch displaying the reversion phenotype increases as a reversion event happens earlier in the kernel development.
Barbara McClintock saw purple dots on maize kernels with an otherwise colorless background.
These spots were caused by the Ds components of the color gene being transposed.
The wild-type (purple) phenotype manifests itself in cells where Ds from the color gene "C" sequence has been lost.

Hence, Barbara McClintock discovered purple patches on the colorless backdrop of maize kernels due to the transposition of the Ds elements out of the color gene.
