Cross over is the first way genes are shuffled to give rise to genetic diversity. Cross over takes place in sexual reproduction. The normal way that cross over occurs is chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other.
If they break the pieces at the same locus in the sequence of base pairs, the result is an exchange of genes called genetic recombination and it ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity occurs.
If this is a true or false question, the answer would be true. Hemodilution means an increase in blood plasma that would result in a dilution of the blood's cellular content.Hope this is the answer and would be of help.
<h2>Regional specialization of Human Nervous System</h2>
Explanation:
The statements that illustrate the regional specialization of human nervous system are-
a. Sensory information may be processed in the occipital lobe or the temporal lobe.
c. Reading a printed word out loud and then thinking of a related word involves the visual cortex, Broca’s area, and the frontal and temporal lobes.
Humans have the most developed nervous system among all the living organisms. Various parts of the nervous system has been specialized for various function. The human brain has been divided into different parts like cerebellum, cerebrum , medulla oblongata etc which are further divided into specialized parts. Each part is specialized to carry out particular function. Moreover, the nervous system has different types of neurons like motor neuron, sensory neurons and interneurons. Each type of neuron has specialized function.
