Vedclass · Answer

(D) The phenomenon of dominance is significant for several reasons:$1$. Dominant genes often mask the expression of recessive,potentially harmful mutations,thereby protecting the organism from deleterious effects.$2$. Dominant alleles contribute to the overall fitness and vigor of an organism,often leading to phenomena like heterosis (hybrid vigor) in cross-breeding.$3$. Because dominant alleles are expressed in both homozygous and heterozygous conditions,they play a crucial role in the survival and adaptation of species.Therefore,all the given statements correctly describe the significance of dominance.

$(S)$ $(X+O)$	$(iv)$ Causes sickle cell anemia
	$(v)$ Causes hemophilia
	$(vi)$ Shows Klinefelter syndrome
