Assertion: Family has a group of related orders and classes. Reason: Families are characterised on the basis of only vegetative characters not by reproductive characters:

Assertion : Number of chromosomes in one genome is equal to number of linkage groups. Reason : Linkage groups give important information about the location of genes in the chromosomes.
