Explanation The carotid arteries originate in the neck from the aortic arch present over the surface of the heart. This artery extends to form the external carotid artery and the internal carotid artery. The external carotid artery transports blood to the neck, esophagus, pharynx and the larynx. The internal carotid artery supplies blood to the brain after passing through the canal...

Chapter 21, Problem 20CP

Summary Introduction

To determine:

The reason, as the compression of the common carotid arteries cause a person to lose consciousness.

Introduction:

The carotid artery transports blood in the neck region after arising from the aortic arch. The application of pressure decreases the flow of the blood to the neck and the brain. This occurs due to the closing of the aperture of the blood vessels. The supply of the oxygenated blood to the brain decreases leading to the feeling of unconsciousness in the person.

In a natural population of outbreeding plants, the variance of the total number of seeds per plant is 16. From the natural population, 20 plants are taken into the laboratory and developed into separate true-breeding lines by self- fertilization-with selection for high, low, or medium number of seeds-for 10 generations. The average variance in the tenth generation in each of the 20 sets is about equal and averages 5.8 across all the sets. Estimate the broad-sense heritability for seed number in this population.
