Duplication provides a source of genetic material for drift, mutation and selection to act upon, making new developmental open doors conceivable. Thus, many have contended that genome duplication is a predominant factor in the advancement of unpredictability and decent variety.

Further explanation

Gene duplication

It is a noteworthy component through which new hereditary material is produced during molecular development. It tends to be characterized as any duplication of a locale of DNA that contains a quality. Quality duplications can emerge as results of a few sorts of mistakes in DNA replication and fix hardware just as through random catch by narrow minded hereditary components. Normal wellsprings of quality duplications incorporate ectopic recombination, aneuploidy, polyploidy, and replication slippage.

Mechanisms of duplication

  1. Ectopic recombination
  2. Replication slippage
  3. Retrotransposition
  4. Aneuploidy

Gene duplication as evolution

Evolution occurs by duplication of genes and we can say that is an occasion by which a gene or some portion of a gene can have two indistinguishable duplicate that cannot be recognized from one another. This wonder is comprehended to be a significant wellspring of oddity in advancement, accommodating an extended collection of sub-atomic exercises. The hidden mutational occasion of duplication might be a traditional quality duplication change inside a chromosome, or a bigger scale occasion including entire chromosomes (aneuploidy) or entire genomes (polyploidy).

<span>It is vitally important to life, any form of life. Life in it's self is what we are all striving to grasp, hold and not let escape. It is the endless search for meaning to understand and comprehend. Evolution which is the symphonic struggle of nature to overcome and create the most suitable specimen ensuring its survival within its species from its predators and the world at large. Duplication is natures way to regenerate and strengthen the gene pool of species. It allows newer generations to improve on the genes to enable it to adapt better to the current environment is is facing. It is a constant and never ending process.</span>

You know that the narrow-sense heritability of milk production in Ayrshire cattle is 0.587. You perform an experiment where you
Paha777 [63]

Answer:

Explanation:

Narrow sense heritability - h​​​​2

​​​​​​selection differential - S

Selection differential is calculated from the difference between the population average and the parental population.

Breeder's equation:

Response to selection - R = h​​​​​​2S

Mean milk production of 10% cows for experiment = 8.9L/hr

Mean milk production of parental population = 5.1L/hr

Selection differential S= 8.9 - 5.1 = 3.8 L/hr

Response to selection = 0.587 × 3.8 = 2.23

Which situations would be most likely to engage the anterior cingulate cortex?
maria [59]

Answer:

Which of the following situations would be most likely to engage the anterior cingulate cortex?

A waiter walks over to your table at a restaurant and holds an open menu in front of you.

You walk into the elevator of your apartment building and press the button for your floor.

You enter your classroom and find someone sitting in your usual seat.

A good friend asks you to remind him of your telephone number.

Explanation:

In order to meet the demand of the surrounding environment   by adjusting  the  motor outputs from the brain to the environments ,a part of the emotion control part of the brain( limbic system) called the anterior cingulate cortex is responsible for this.

Anatomically, the limbic system is made up of the primarily the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia and cingulate gyrus.

Based on the this its(anterior cingulate cortex) functions are formation of emotion in the limbic system, and  possessing  of memory and learning.

it is also a major  parts of  of pain networks for pain modulation and perception.

Therefore whenever there is  change in the environment  from the prestored condition in the brain,(e.g the usual seat  in the class room  occupied above) the anterior cingulate cortex adjust the motor input from the brain to adapt to the new environment to take an action,whih in this case  leads to the reclaiming of the seat or any other necessary proactive action.
