LAW OF DOMINANCE
The law of dominance states that one of the pairs of inherited traits will be dominant and the others recessive unless both the factors are recessive.
The dominant allele masks the effect of recessive allele. It explains the expression of only one of the parental characters in a monohybrid cross in F1 and expression of both in F2.
- Characters are controlled by discrete units called factors.
- In a dissimilar pair of factors one member of pair dominate the other. For example: allele of tallness (T) is dominant over allele of dwarf (t).

The inert pair theory was proposed by Sidgwick. He along with Powell accounted for the shapes of several molecules and correlated the shapes with some of their physical properties.
nert pair effect is defined as The non-participation of the two s electrons in bonding due to the high energy needed for unpairing them.

R = {(a, b) : 2 divides a – b}
where R is in the set Z of integers.
(i) a – a = 0 = 2 .0
∴ 2 divides a – a ⇒ (a, a) ∈ R ⇒ R is reflexive.
(ii) Let (a, a) ∈ R ∴ 2 divides a – b ⇒ a – b = 2 n for some n ∈ Z ⇒ b – a = 2 (–n)
⇒ 2 divides b – a ⇒ (b. a) ∈ R
(a, ft) G R ⇒ (b, a) ∈ R ∴ R is symmetric.
(iii) Let (a, b) and (b, c) ∈ R
2 divides a – b and b – c both ∴ a – b = 2 n1 and b – c = 2 n2 for some n1, n2 ∈ Z ∴ (a – b) + (b – c)= 2 n1 + 2 n2 ⇒ a – c = 2 (n1 + n2 )
⇒ 2 divides a – c
⇒ (a, c) ∈ R
∴ (a,b), (b,c) ∈ R ⇒ (a, c) ∈ R
∴ R is transitive
From (i), (ii), (iii) it follows that R is an equivalence relation.

Throughout his life, the peddler had never known respect. He was always treated coldly by the world. For the first time in his life, he was honoured and respected as if he were a captain. Even after the truth was exposed, the daughter continued to treat him in a similar way. The way he was treated encouraged him to behave in a like manner. He signed the letter as Captain von Stahle so as to underline the impact of Edla's goodness on him.

What is Occupational Structure?
The occupational structure of a nation refers to the percentage of its workforce employed in various economic ventures. To put it in other words, articulating how many of the total working population are employed in agriculture and associated activities and how many of them are involved in manufacturing and service sector can be identified from the occupational structure of the nation.
Occupational Structure in Colonial India
During the colonial period, the occupational structure of India, i.e., the allocation of working people across various industries and sectors, explicated small hint of change. The agricultural sector valued for the highest share of the workforce, which normally prevailed at a high of 70 – 75 % while the manufacturing and the services sectors estimated for only 10 and 15-20 % sequentially. Another outstanding perspective was the growing geographical variation. Parts of the then Madras Presidency (including areas of the present-day states of Tamil Nadu, Kerala, Andhra Pradesh and Karnataka), Bombay and Bengal observed a drop in the dependence of the workforce on the agricultural sector with a corresponding increase in the production and the services sectors. However, there was an increase in the share of the workforce in agriculture during the same time in states such as Rajasthan, Odhisa and Punjab.
