$(i)$ and $(ii)$

Vedclass · Answer

(B) Speciation is the evolutionary process by which populations evolve to become distinct species.$(i)$ Significant changes in the $DNA$ of germ cells lead to variations that are inherited by the next generation,which is a fundamental requirement for speciation.$(ii)$ $A$ change in the chromosome number in gametes (such as polyploidy) can create reproductive isolation from the parent population,leading to the formation of a new species.$(iii)$ If there is no change in the genetic material,the offspring will be identical to the parents,and no new species will be formed.$(iv)$ Mating is necessary for sexual reproduction and gene flow; lack of mating does not inherently cause speciation.Therefore,statements $(i)$ and $(ii)$ are correct.

List-$I$	List-$II$
$1$. Acquired trait	$a$. Wings of a bird and wings of a butterfly
$2$. Evidence of evolution	$b$. Wings of a bird and forelimb of a lizard
$3$. Homologous organs	$c$. Docked tail of a mouse
$4$. Analogous organs	$d$. Fossils

New species may be formed if
$(i)$ $DNA$ undergoes significant changes in germ cells
$(ii)$ chromosome number changes in the gamete
$(iii)$ there is no change in the genetic material
$(iv)$ mating does not take place
