Answer:

75% chance of purple, 25% of white

Explanation:

Heterozygous means having two different alleles of a gene

This must mean they are Purple dominant and white recessive

This will be represented as Pw

$\left[\begin{array}{ccc} &P&w\\P&PP&Pw\\w&Pw&ww\end{array}\right]$

This, called a punnet square, calculates the probability of the gene outcome. The top <em>Pw </em>represents one parent and the <em>Pw</em> on the left side represent the other.

In the diagram, each combo of letters ( <em>PP, Pw, Pw, ww </em>) represents a 25% of what gene the offspring will have. <em>PP </em>means it'll be purple, and so does both <em>Pw's</em>. <em>ww</em> means white flowers though because there is no dominant trait and only recessive. This is the only way for a recessive trait to appear in a child.

Therefore there is a 75% chance of the offspring having purple flowers and a 25% chance of the offspring have white flowers.
