Which of the following is incorrectly paired?

Traits controlled by genes located on autosomes are said to be

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 List-$I$ with List-$II$ :

List-$I$ (Type of Inheritance)	List-$II$ (Example)
$A$. Incomplete dominance	$I$. Blood groups in human
$B$. Co-dominance	$II$. Flower colour in Antirrhinum
$C$. Pleiotropy	$III$. Skin colour in human
$D$. Polygenic inheritance	$IV$. Phenylketonuria

Choose the correct answer from the options given below :

The reason for the difference in genetic makeup in each animal species is:

$Statement A$: 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.
