Two genes ‘A’ and ‘B’ are linked. In a dihybrid cross involving these two genes,

Dominance Recessive A dominant factor or allele expresses itself in the presence or absence of a recessive trait. A recessive trait is able to express itself only in the absence of a dominant...

(i) CH3CH2OH + PCl5 => CH3CH2Cl + POCl3 + HCl (ii) CH3CH2OH + Na => CH3CH2ONa + H2

d. The allels of two genes are segregating independently.

d. phenotypes - 4; genotypes - 9

c. oncogenes

(4) Cross-linked or network polymers are usually formed from bi-functional & tri-functional monomers and contains strong covalent bond between various linear polymer chains like Melamine, Bakelite etc.

23minutes. A+B =2 minutes A returns=1 minute A+C=7 minutes A returns= 1 minute A+D=10 minutes A comes back =1 minute Leaves lamp and crosses again=1 minute Total 23 minutes.
