Alleles segregate during gamete formation.

One allele can be dominant over another.

Genes on different chromosomes assort independently.

Genes on the same chromosome are always inherited together (linkage).

All the transition metals except scandium form MO oxides which are ionic.

The highest oxidation number corresponding to the group number in transition metal oxides is attained in $ext{Sc}_2ext{O}_3$ to $ext{Mn}_2ext{O}_7$.

Basic character increases from $ext{V}_2ext{O}_3$ to $ext{V}_2ext{O}_4$ to $ext{V}_2ext{O}_5$.

$ext{CrO}$ is basic but $ext{Cr}_2ext{O}_3$ is amphoteric.
