Ans:-
Mendel's Law of Dominance states that in a heterozygote, the dominant allele

visible in the phenotype. Both alleles are transmitted unchanged to the
offspring, but the recessive trait reappears in the homozygous recessive
condition.
(v) In what

Ans:- The
Upper Palaeolithic industries showed progress with the development of blade and
