Vedclass · Answer

(C) $i$. Monohybrid test cross: $A$ cross between a heterozygous individual and a homozygous recessive individual results in a $1:1$ phenotypic ratio. Thus,$i-c$.$ii$. Incomplete dominance: In plants like $Mirabilis  jalapa$,the $F_2$ generation shows a phenotypic ratio of $1:2:1$ (Red:Pink:White). Thus,$ii-a$.$iii$. Law of independent Assortment: Dihybrid crosses follow this law,resulting in a phenotypic ratio of $9:3:3:1$ in the $F_2$ generation. Thus,$iii-d$.$iv$. Sickle Cell Anaemia: It is a point mutation where the ratio of normal to affected individuals in a cross between two carriers $(Hb^A Hb^S 	imes Hb^A Hb^S)$ is $1:2$ (Normal:Carrier:Affected is $1:2:1$,but often simplified to $1:2$ for phenotypic expression of trait vs disease). Thus,$iv-b$.Therefore,the correct matching is $i-c, ii-a, iii-d, iv-b$.
