Angiosperms have a vascular system and can live is harsher environments which means they can reproduce a lot more often and faster.

LINKAGE
Independent assortment refers to the allele segregation of two different genes. They are expected to be segregated from each other independently.This is not seen in monohybrids, they are usually heterozygous for an allelic pair only. Link genes cannot assort independently. These are inherited together during meiosis phase of sexual reproduction. Usually genes that are close together will tend to stick together resulting into inheritance of genes as pairs.
