In $Drosophila$,during organ differentiation,if one organ is transformed into another (e.g.,legs instead of wings),what is the gene responsible for such transformation called?

Match the following columns correctly:

Column-$I$	Column-$II$
$(a)$ $1 : 2 : 1$	$(i)$ Test cross
$(b)$ $3 : 1$	$(ii)$ Law of Dominance
$(c)$ $9 : 3 : 3 : 1$	$(iii)$ Incomplete Dominance
$(d)$ $1 : 1 : 1 : 1$	$(iv)$ Law of Independent Assortment
	$(v)$ Law of Segregation

$Statement A$: For a particular character in an individual,each gamete gets only one allele.
$Statement B$: Chromatids of a chromosome split (separate) and move towards opposite poles during anaphase of mitosis.

Read all the given statements carefully and determine the number of correct statements.
$(1)$ Mutations are not hereditary.
$(2)$ Male $Drosophila$ flies do not show crossing over.
$(3)$ In honeybees,the male bee is diploid.
$(4)$ In a frame-shift mutation,one nitrogen base is replaced by another nitrogen base at a specific position.
$(5)$ Genes are responsible for inheritance.

Which of the following statements are false?
$I.$ $A$ dominant allele determines the phenotype when paired with a recessive allele.
$II.$ $A$ recessive allele is weaker than a dominant allele.
$III.$ $A$ recessive allele does not show its effects when paired with a dominant allele.
$IV.$ $A$ dominant allele is always better for an organism.

Match the terms in column-$I$ with their description in column-$II$ and choose the correct option.

Column-$I$	Column-$II$
$(A)$ Dominance	$(i)$ Many genes govern a single character
$(B)$ Codominance	$(ii)$ In a heterozygous organism only one allele expresses itself
$(C)$ Pleiotropy	$(iii)$ In a heterozygous organism both alleles express themselves fully
$(D)$ Polygenic inheritance	$(iv)$ $A$ single gene influences many characters
