Amylase enzyme acts on the starch.

Seed traits of a given plant species following genetic inheritance are:

$S=$ long, $s=$ short;
$W=$ wrinkled, $w=$ smooth;
$Y=$ yellow, $y=$ white;
$R=$ ribbed, $r=$ grooved
A cross was performed between two plants, $P$ and $Q$ of the same species; wherein, the plant $P$ bears seeds that are homozygous recessive for grooved, homozygous dominant for long trait, and heterozygous for wrinkled texture and yellow colour. The plant $Q$ bears seeds that are homozygous recessive for short and smooth traits, homozygous dominant for yellow colour and ribbed trait. Given that there are no influencing factors, state the resulting phenotype of the offspring for this cross.

The phenomenon of independent assortment refers to:

"When two pairs of traits are combined in a hybrid, segregation of one pair of characters is independent of the other pair of characters".

Which of Mendel's laws/principles explains the above statement?
