Vedclass · Answer

(D) Mendel's laws of inheritance,specifically the Law of Dominance and the Law of Independent Assortment,are not universally applicable. $1$. Linkage is an exception to the Law of Independent Assortment,as genes located on the same chromosome tend to be inherited together. $2$. Incomplete dominance is an exception to the Law of Dominance,where the $F_1$ hybrid shows an intermediate phenotype rather than the dominant trait. $3$. Co-dominance is also an exception to the Law of Dominance,where both alleles are expressed equally in the heterozygote. Therefore,all the given options are exceptions to Mendelism.

Column-$I$	Column-$II$
$(A)$ Dominance	$(1)$ Many genes govern a single character.
$(B)$ Co-dominance	$(2)$ In a heterozygous organism, only one allele expresses itself.
$(C)$ Pleiotropy	$(3)$ In a heterozygous organism, both alleles express themselves fully.
$(D)$ Polygenic inheritance	$(4)$ $A$ single gene influences many characters.
