Answer:
b. average heterozygosity
Explanation:
From the available options:
a. nucleotide variability
b. average heterozygosity
c. average number of loci
d. geographic variability
Nucleotide variability represents a form of genetic variation that occur as a result of difference in nucleotide sequence of deoxy ribonucleic acid.
The locus is a region on the chromosome where genes are located. Average number of locus thus refers to total number of loci per total number of individuals in a population.
Geographic variability refers to difference in genetic traits across the various geographical distribution of a population.
Average heterozygosity is the percentage or proportion of heterozygous individuals for a trait within a population. It is a common measure of genetic variation in a population.
When a mutation occur within a population and this leads to the introduction of a new allele at a locus for which some individuals within the population are homozygous, it will directly affect the average heterozygosity of the population because more individuals will lose their homozygosity and become heterozygous.
<em>The correct option is b.</em>
Answer:
The correct answer is: True.
Explanation:
- The writing of a person is controlled by an region located in the left part of frontal lobe of the brain which is known as the Broca's area.
- Writing is a motor impulse send by the brain to the hand and fingers.
- However, no two individual can have the same hand-writing.
- This is because hand-writing is not only dependent on the brain to hand motor co-ordination.
- It also depends upon the psychology, mentality, thought process, state of mind, nature of the person and also the influence of the surroundings on the person.
- It also depends on the preference of the person to keep his writing artistic or simple or illegible.
- All these factors can never match between two persons.
- This is the reason, no two persons can share the exactly same hand-writing.
